Crew of Edens Zero
- Badass Crew: The main characters establish themselves as this before their adventure officially begins. Shiki is a Gravity Master with superpowers from a bygone age; Rebecca is The Gunslinger with twin blasters and uncanny marksmanship; Happy, who is really an alien cat android, transforms into said twin blasters; Weisz is a Technopath and Ace Pilot; and Homura is a Master Swordswoman.
- Cool Starship: The Edens Zero is an extravagant black-and-gold dreadnought with a demonic-looking dragon's head at its prow. It also includes various luxuries such as a massive bathhouse with a cosmic skylight and superpower-inducing water, an Unlimited Wardrobe factory, a kitchen that automatically provides whatever food the crew wants, and a built-in fireworks launcher. Its Skull Fairy form is also impressive with a similar-looking dragon head.
- Faster-Than-Light Travel: The ship has a fast travel function that warps immediately to any location it's already been to. This would totally remove the need to travel through Dragonfall if Ziggy didn't already delete all of the ship's stored coordinates beyond the Sakura Cosmos.
- Fun with Acronyms: The first half of "Edens Zero" is an acronym for "Ether Drive Eternal Navigation Ship".
- Living Ship: The ship is technically alive according to Sister, but only when all Four Shining Stars are present and accounted for.
- No Waterproofing in the Future: Averted. The Spa of Eden has bathwater that is tailored for robots just as much as humans.
- Ragtag Bunch of Misfits: The core crew members consist of a castaway with No Social Skills who was Raised by Robots; a wannabe web celebrity with little online talent and presence; an alien cat who was made into an robot after a fatal accident; a self-centered thief and womanizer trapped in another timeline; an android with no memories and a desire for humanity; and a socially awkward samurai who habitually vocalizes her every thought.
- Spell My Name with a "The": The official translation flip-flops between this with the Edens Zero itself.
Debut: Chapter 1
Homeworld: Granbell, Sakura Cosmos
Ether Gear: Gravity Ether Gear
The adoptive grandson of Demon King Ziggy, and the sole human inhabitant of Planet Granbell, where he was raised in an abandoned theme park run by robots. He gets swept up on a space-faring adventure with Rebecca and Happy to explore new worlds across the cosmos and make as many friends as he can along the way, but a lifetime without human contact has left his social skills somewhat lacking. To overcome this, he has made it his life's goal to find the legendary goddess Mother, using the Edens Zero—his birthright from his late grandfather—to do it.
- Adorkable: He might creep some people out with his friend-making advances, but he's just so earnest in his determination and enthusiasm that it makes him quite endearing.
- All of the Other Reindeer: Upon leaving Granbell, almost everyone else he meets besides Rebecca and Happy either thinks he's some kind of friend-obsessed nutjob, or wants to hunt him down to exploit his powers for personal gain.
- Anti-Hero: He starts out as a mildly Pragmatic Hero, but as he grows more attached to his friends, he begins to straddle the line between that and an Unscrupulous Hero: he will do whatever he can to save as many lives as possible, but when it comes down to a Sadistic Choice between saving his friends or a bunch of strangers, he will pick his friends and not give a damn about what anyone else thinks.
- Barbarian Longhair: He is introduced with long, messy, greasy hair that has never been cut in his entire life, since none of the robots he grew up with ever saw it as a problem. It bugs Rebecca so much that she cuts it off in his sleep, giving him his standard Shonen Hair look. He later gives this hairstyle to his Digital Avatar on Digitalis as a memento to his old home, but it gets chopped off again by Jamilov's scythe.
- Berserk Button: As is standard for a Hiro Mashima protagonist, he will never tolerate anyone who harms his friends or makes them cry.
- Bodyguarding a Badass: He feels this way about Rebecca, who recruits him as her "bodyguard" on her adventures, despite being a perfectly capable fighter on her own with her Happy Blasters.
- Chivalrous Pervert: While it's treated as one of his lesser character traits, he openly shows a lustful attraction towards attractive girls, mixed with a sense of curiosity towards human women since he hadn't interacted with any before meeting Rebecca. Nevertheless, this doesn't stand in the way of his protective and supportive stance towards them.
- Clothing Damage: When using the full extent of his Ether Gear, the gravity around him becomes so intense that it rips his shirt to shreds until he's a Walking Shirtless Scene.
- Corrupt the Cutie: It's heavily implied that Weisz had a hand in Shiki's growing awareness of the opposite sex, since it doesn't start until after Weisz officially sticks around.
- Country Mouse: Having spent his entire life on an island filled with century-old robots, he has trouble grasping the basics of modern space travel, and is mesmerized by the universe's more up-to-date, futuristic technology.
- Deconstructed Character Archetype: He serves as one for the Stock Shōnen Hero, though it also leads to a Decon-Recon Switch on several accounts:
- His utter obsession with making new friends makes him come across as more of an annoying and creepy weirdo than an inspiring figure, while his Hot-Blooded nature tends to scare away any potential friend he wants to make. However, it also means he views everyone equally regardless of whether they're human or bot, which, in a universe chock full of mutual prejudices, ultimately earns him a loyal group of True Companions from both sides in the end.
- His need to put his friends before himself nearly gets him marooned forever on his home planet when all his robot friends are about to shut down permanently, as the robots know he would dedicate his entire life trying to fix them if he knew what would happen.
- His dedication to protecting his friends causes him to prioritize their safety above anything else, which leads him to outright ignore a villain's threat of harming Innocent Bystanders if Shiki stands in the way of hurting his friends—which he fully admits is something a "hero of justice" would never do.
- Doomed Hometown: Although he never realizes it, Granbell is already doomed by the time Rebecca and Happy arrive, as the other robots are on the verge of breaking down for good. It's also revealed that their attempt to kill him and Rebecca after seemingly coming down with a virus was actually a covert evacuation operation meant solely for him.
- Energy Ball: His Gravity Cannon is a ball of concentrated gravity that he hurls at enemies. He's later inspired by Rebecca fighting style to compress these balls into smaller bullets that he fires from his knuckles like a shotgun.
- The Engineer: Subverted. He thinks the robots on Granbell need him around to make sure they're in working condition, even though his skill amounts to Percussive Maintenance at best, but they reveal later on that they have an automated self-repair function, and led him to believe he was the one fixing them as they didn't have the heart to tell him their batteries were Secretly Dying, and that there was nothing he could do about it.
- Face of a Thug: Downplayed. Weisz describes him as having the face of a Beetle Maniac, but Shiki is extremely kind and friendly. He's also afraid of bugs, ironically.
- Famed In-Story: Not from the outset as he starts out as an outcast from human society, but the first chapter indicates that Shiki's name will eventually become known across the universe.
- Fantastic Fighting Style: His "Magimech Attack" style, which is only possible for a Gravity Ether Gear user such as himself.
- Friend to All Living Things: Exaggerated; he considers himself a friend to any sentient being that wouldn't normally be considered "alive", including robots and digital lifeforms.
- Goggles Do Nothing: The outfit he wears in the Guilst arc comes with a pair of goggles, but they're just there to make him look cool.
- Gravity Master: His Gravity Ether Gear lets him alter the gravity of himself or any person and object he touches, allowing them to float, run along walls, and "fall" sideways across great distances when in midair. His weight-shifting abilities also create the illusion of Super Strength, making his punches hit with the force of a speeding truck, or making a spaceship about as light as a beach ball. According to Shiki, however, there's a limit to how light he can make things.
- Hurricane Kick: His Gravity Windmill Kick is a justified example, as he lightens his own personal gravity to stay in midair.
- I Am Who?: Shiki is astonished to learn that his grandfather was not merely a theme park animatronic, but a well-known interstellar traveler who found him on his return journey after failing to find Mother, and left him quite the inheritance of a massive warship and a stewardess who regards him as "the new Demon King".
- Idiot Hero: He's a bit of a dunce and his most complex strategies boil down to: "Hit it hard. If that doesn't work, use a different move and hit it harder." He also asks to break open a window in space so he can shout back down to Granbell. Most of this can be chalked up to how sheltered he is, having grown up among robots designed to run a fantasy theme park.
- I Just Want to Have Friends: He desperately longs to make new friends after spending over a decade living among robots who encouraged him to do just that. However, his commitment to the robots holds him back from doing so. Once he overcomes this issue, he officially makes it his Goal in Life to make 100 friends in the universe, with Rebecca and Happy starting as his first.
- Lightning Bruiser: Shiki is easily the fastest, hardest-hitting, and toughest member of the team thanks to his Ether Gear. He creates massive craters with his punches, can slide and fly around fast enough to catch up to hoverbikes, and has taken a number of attacks from bounty hunters and criminals.
- Loser Protagonist: He's a castaway Raised by Robots who starts at the bottom rung of the adventurers guild, where everyone besides his closest friends think he's a total nutcase for claiming to have seen Mother.
- Mad Libs Catchphrase: "X is/are awesome!"
- Magnetic Hero: His kindness and willingness to befriend anyone regardless of their race ends up winning over a number of people once they get over his social quirks. Lampshaded by Rebecca, who is perturbed that Shiki managed to make two new friends in the brief time she was kidnapped on Guilst.
- Meaningful Rename: Since he doesn't know his own last name, if he has one at all, Rebecca decides to register him into Shooting Starlight as "Shiki Granbell", naming him after his home planet. Shiki loves it so much that he keeps it for himself.
- Megaton Punch: His Gravity Fist strikes his enemy with such strong gravitational force that it completely shatters the ground hundreds of feet around him.
- Mysterious Past: Much about Shiki's life before he was found by the Demon King and raised on an abandoned robot planet remains a mystery, especially since he is recognized by a being believed to be the goddess of the cosmos.
- Naïve Newcomer: He reacts to every new person and place he comes across with total awe and wonder, to the degree that he fails to immediately read tense situations or danger.
- Named After Their Planet: He's had Only One Name for his entire life, as far as Shiki and Rebecca are concerned, so when Rebecca registers him into Shooting Starlight, she decides to give him the surname "Granbell" after the planet she found him on.
- No Sense of Personal Space: Having never interacted with another human being in his life before meeting Rebecca, his first instinct upon meeting a new person is to squish their face, and boobs if they have them.
- No Social Skills: Since he grew up living among robots, he has no idea how to interact with real people. The scary and intense faces he makes, not to mention the unwanted touching, nearly drives away the first friend he makes.
- Not Quite Flight: Whenever he needs to get across long distances in a hurry, he leaps high into the air and changes his own personal gravity to "fly" by falling sideways.
- Otaku: He's a huge geek when it comes to fantasy role-play, likely cultivated by his home planet's LARP attraction. He also mentions Fantasy Character Classes when thinking about getting a whole party together for the voyage to Mother, and declares he's changed his job to "thief" when stealing Young Weisz's briefcase.
- Pre-Asskicking One-Liner: Gets a character-defining one when he faces Garrot, solidifying who he is after Mother wonders whether he'll be a legendary hero or a havoc-wreaking Demon King:Shiki: I don't follow your rules. My friend is more important. I'm not some hero fighting for justice. If you hurt my friends...then I'm willing to be the Demon King!!!
- Raised by Robots: He was raised from childhood by the robotic attractions and employees at the Granbell Kingdom theme park, with the one who first discovered him being his "grandfather", the Demon King. They were friendly with him and gave him a good home, but this meant he never really interacted with real humans until Rebecca came along. Once off planet, he has trouble adjusting to talking and meeting with other people.
- Rapid-Fire Fisticuffs: His Gravity Fist Frenzy becomes this when used against a single opponent, delivering a No-Holds-Barred Beatdown in no time flat.
- Shonen Hair: After Rebecca gives him his first haircut in a decade, Shiki keeps his hair messy and spiky.
- Slide Attack: He can change his gravity to slide across the floor as if it were down a vertical wall.
- Stock Shōnen Hero: Much like his predecessors, Shiki is a cheerful and kindhearted teenager with a wide-eyed look on life. He's excitable and is deeply invested in any friendships he makes, but his attempts to make friends are hampered by his poor social skills. In battle, he's a Close-Range Combatant who makes up for his lack of complex strategy with extreme brute force.
- Swiss-Army Superpower: His ability to manipulate gravity comes with a wide variety of applications. He can manipulate gravitational force to emulate Super Strength, slide along the ground at high speeds, fly by falling sideways, Wall Run, and much more.
- Temporal Theme Naming: Shiki's name is Japanese for "four seasons". This is in keeping with Mashima's personal tradition of naming main characters after seasons, following Haru (spring) from Rave Master, Natsu (summer) from Fairy Tail, Aki (autumn) from Monster Soul, and Mafuyu (winter) from the one-shot Fighting Force Mixture. Incidentally, Mashima's Monster Hunter adaptation, Monster Hunter Orage, also stars a protagonist named Shiki.
- Tragic Dream: He convinced Ziggy to teach him Ether Gear so he could defeat him in a fair fight. That dream came to a crashing halt when Ziggy broke down from age before he could finish teaching Shiki everything he knew. When Shiki finds out that Ziggy had a Tragic Dream of his own, however, Shiki realizes he has another way to "defeat" him and commits himself to fulfilling that dream.
- Trauma Button: Though it's mostly Played for Laughs, Shiki breaks down in tears whenever anything reminds him of his old friends on Planet Granbell, whether it's remembering the way they betrayed him and chased him away, or wondering if they all turned back to normal.
- Unscrupulous Hero: When Homura is about to get punished while she and Shiki are imprisoned in Sun Jewel's labor district, none of the other prisoners are willing to help her under threat of retribution on the whole community. This sits very poorly with Shiki, who decides to stop playing nice and focus on getting Homura back no matter the cost, summed up in this very threatening Badass Boast to the warden:
- Wall Run: One of his Gravity Ether Gear powers involves running across walls like they're horizontal floors.
- Why Did It Have to Be Snakes?: He's deathly afraid of bugs, which causes him to completely freeze up whenever he's anywhere near a huge number of them. To get around this, he and his friends try to get him to think of bugs as any other creature, such as octopi, cats, and birds.
- The World Is Just Awesome: Because he's so sheltered, Shiki jumps for joy whenever he learns something new and is constantly in awe of all the things he's encountering with Rebecca.
- Would Hit a Girl:
- He publicly humiliates Labilia for bullying Rebecca by flipping her upside-down in the air with his gravity powers, and likely would've done worse had Rebecca not pulled him away to avoid making more of a scene.
- He has no issue targeting the fake Sister, who, despite having no combat ability herself to speak of, sufficiently pissed him off for using one of her own men as a Bulletproof Human Shield.
- Wrong Genre Savvy: He seems to think the world works like it does in Fairy Tail, going by the lengths he goes to make friends and expects the Shooting Starlight guild to be like one big family, and he's sorely disappointed when all the people he meets either run away from him, mock him, or generally try not to pay him any attention. He's also under the impression that the adventures they go on are like an Eastern RPG, which he uses to justify stealing when he spontaneously decides to undergo a "class change".
Debut: Chapter 1
Homeworld: Blue Garden, Sakura Cosmos
An amateur B-Cuber from Planet Blue Garden who wants to hit one million subscribers for her obscure video account, Aoneko Channel, by traveling to different planets and recording whatever interesting thing she can find. As the first human friend Shiki makes, she ends up saving his life when all his robot friends suddenly turn on him, taking him with her to explore the cosmos. When Shiki decides to search for Mother, Rebecca eagerly goes along with his suggestion to record never-before-seen evidence of her existence, thinking this is the perfect ticket to online fame.
- Affectionate Nickname: A few of her fellow B-Cubers have taken to calling her "Becky" in Kodansha's translation as a sign of their growing admiration for her.
- Animal-Eared Headband: She keeps a pair of fake cat ears around, which she wears for her videos.
- Badass in Distress: During the Guilst arc, she's captured along with dozens of other B-cubers thanks to being ambushed without warning. While in captivity, she leads the other women in figuring out a way to escape. She does end up needing to be rescued when Illega spots her, thanks to her having no weapons and falling victim to his paralytic toxin, but the next time they cross paths, she's able to swipe Illega's gun at the first opportunity and take him down herself.
- Badass Normal: While she lacks the Ether Gear powers most of her companions have, being The Gunslinger with Improbable Aiming Skills makes her just as capable of clearing out a room of enemies so long as she has access to an Ether gun. She becomes a temporary Empowered Badass Normal whenever she bathes in the Spa of Eden, which enhances her Ether flow into a rudimentary Ether Gear.
- Bathtub Bonding: She gets a fair bit of this Happy, and joined later by Homura, since they always share the Spa of Eden together.
- Beware the Nice Ones: She might be a friendly teenager, but she's a friendly teenager with a pair of guns, and she knows how to use them.
- Big Eater: She'll eat anything that looks delicious, no matter how much there is or how much she's already eaten. Just saying the word "delicious" will start her salivating.
- Boom, Headshot!: She prefers to deal with her opponents by shooting them in the head with her Happy Blasters. Luckily, these Ether bullets aren't lethal, but she gets her points across by putting a gun up to someone's head.
- Broken Pedestal: Downplayed. She's shocked and a bit disappointed to learn that Professor Weisz, her and Happy's beloved Parental Substitute, used to be a thief and overall scumbag when she sees his younger self in person. However, she fully understands that these issues are long behind him, and is pleased whenever she sees Young Weisz act Not So Different from the Professor.
- Cloudcuckoolander: Downplayed. Her head isn't always in the clouds, but she can get lost in them easily when she sees something new or peculiar.
- Dangerously Short Skirt: Deliberately wears one typically to entice viewers for her web videos.
- Does Not Know Her Own Strength: Her first attempt at using Ether Gear causes her to carelessly fire a Kamehame Hadoken through the Edens Zero's skylight, nearly getting herself sucked out into the vacuum of space.
- Friend to All Living Things: She will accept any friendship whether it's with an animal, a robot, or both, owing this mindset to how she was able to continue her friendship with Happy after he was run over by a truck and revived as a machine when she was just a little girl.
- A Friend in Need: After Shiki saves her life from his rogue robot friends on Granbell, Rebecca proves herself to be a true friend by taking him aboard her ship to escape without any obligation to do so, even though he already offered to stay behind and hold them off.
- Gamer Chick: She's a self-admitted gamer who spent most of her time playing with Happy over actually adventuring and working. An omake chapter also shows her dealing with the frustration of being mistaken for a G.I.R.L. in an online game.
- Genki Girl: She can get very excitable at times, especially when she discovers new inspiration for a video, with Happy being there to keep her grounded.
- Goal in Life: Hers is getting one million subscribers on B-Cube, the in-series version of YouTube. She has a long way to go as she starts out with barely over 100.
- Guns Akimbo: To accommodate for her twin Happy Blasters.
- The Gunslinger: She's a deft shot with just about any Ether gun she has her hands on, namely her Happy Blasters, dishing out headshots against at least a dozen thugs in a row, and a storm of bullets when a single shot won't cut it.
- High Hopes, Zero Talent:
- Despite her lofty aspirations to be a famous B-Cuber, she is a complete amateur who relies almost exclusively on recording whatever random thing catches her interest at that moment, which results in videos that are too scattershot and unstructured, making her an easy target of mockery from Labilia. As for what she considers to be "good" content, it ranges from letting Shiki fly her ship with no experience to having him dance in a bunny girl costume, which gives her friends a firm grasp of why her videos are so unpopular.
- Aoneko Channel sees a boost in popularity after Rebecca gets a shout-out from the B-Cubers she helped rescue from Guilst, yet all the reactions to her videos turn out to be negative. This doesn't faze Rebecca, who is only happy that she's finally getting more attention and vows to make better videos, but does nothing to actually improve her craft. Labilia later calls her out on this, accurately assessing that she didn't become popular because anyone actually cares about her content.
- Holographic Terminal: Her necklace die contains a B-Cube terminal that lets her record, upload, and watch videos.
- Honor Before Reason: Her pride as a gamer leads her to strongly resist using cheats against Jamilov in the Digitalis arc, despite Young Weisz's sound argument that Jamilov is using cheats to thrash them himself, though she makes an equally strong counterpoint that they'd risk getting themselves banned from the game before they have a chance to save Hermit.
- I Know Mortal Kombat: It's all but stated that she got her Improbable Aiming Skills from playing First-Person Shooter games for Mother knows how long.
- Improbable Aiming Skills: Her ability to perform no fewer than a dozen headshots within a matter of moments is an uncanny skill for a marksman, since a person's head is too small and evasive to serve as a practical target.
- Interspecies Friendship: She is a believer that whether one is human, animal, or machine doesn't matter when it comes to being friends, which stems from her own friendship with Happy, an alien cat who was turned into a machine.
- Kindhearted Cat Lover: While she has a mean temper, she's a sweetheart who is dear friends with Happy and melts over anything that remotely looks like a cat.
- The Lad-ette: Normally a Genki Girl, she adopts a much more crass attitude when shooting people up with her Happy Blasters.
- Let's Get Dangerous!: She often gives the impression of an ordinary teen out of her depth, but the instant she takes hold of her Happy Blasters, she turns into a master-class marksman.
- Loser Protagonist: Like Shiki, she's at the bottom rung of the Shooting Starlight guild, and she's spent most of her time either making weird online videos or holing herself up playing games.
- Mood-Swinger: When the opportunity to fight arises, she turns from a Genki Girl into a Hot-Blooded Lad-ette and back in the bling of an eye.
- Ms. Fanservice: Shots of Rebecca tend to be set up to emphasize her large breasts, butt, and legs. It veers slightly into Shameless Fanservice Girl when Happy lampshades how she's wearing her skirt slightly shorter than usual to get more views for her channel, but she draws the line at unwanted groping and peeping, and she censors her holographic videos for whenever someone tries getting a look up her skirt.
- Mysterious Past: Apart from being an avid B-Cuber who was abandoned as a child and grew up with an android cat, she's kept much about herself a secret from the people she knows.
- Nice Girl: She becomes quick friends with Shiki after a short bit of friction, is wholly unbiased in his relationship with the Granbell robots—largely due to her own experiences with Happy—and brings him along on their journey across the universe when he wants to make more friends beyond his planet.
- No Such Thing as Bad Publicity: Rebecca gets a huge popularity boost following a shout-out from all the popular B-Cubers she had a hand in rescuing from Guilst. She's not bothered in the slightest that her videos are getting downvoted due to their trashy content, seeing it as the perfect chance to make better videos now that she has the attention.
- Parental Abandonment: She's been living on her own with Happy since she was just a little girl, reasoning that she was abandoned by her parents.
- Plucky Girl: She's capable of pulling through just about any hardship with a smile on her face in the end. She does, however, come close to getting broken after getting kidnapped and suffering a Trauma Conga Line in the Guilst arc, though she's emotionally resilient enough to remain strong for the other kidnapped B-Cubers until they're all safe.
- She's Got Legs: Several of her fanservice shots are centered around her legs and buttocks. She herself is aware of this, as she has a shorter skirt for when she wants to attract viewers.
- Small Name, Big Ego: Rebecca fancies herself as an internet celebrity who needs to go Clark Kenting in public, even though she hardly has any views on her channel.
- Street Urchin: She grew up on the streets of Blue Garden after being separated from her parents, if not abandoned by them, and used to live in a shack on the outskirts of the city, with only Happy to keep her company.
- The Team Normal: She's the only human member of the core team who doesn't have Ether Gear, but makes up for it by being a Badass Normal Gunslinger. She also actively works to break out of this by learning her own Ether Gear.
- Too Kinky to Torture: Plays the part out of defiance while she's captured. When being blasted by her bindings from Ganoff in an attempt to break her and curb any rebellion from the other B-Cubers, Rebecca endures it pretty well and starts talking about how she could use this scene for a video and the potential of this being flagged for "inappropriate content."
- Trauma Conga Line: She suffers pretty badly in the Guilst arc, where she's enslaved, sexually harassed, stripped of her clothes, paralyzed, and forced to kneel under Illega's foot. While she seems to pull through it all mostly unaffected, she suffers a brief and sudden emotional breakdown from her experiences once she's safe and sound on the Edens Zero.
- Verbal Tic: When in full Guns Akimbo mode in Japanese, Rebecca ends her sentences with "zeyo", a comically super-masculine particle. Kodansha's translation opts to capture that level of weirdness by having her call people "ducky", which is essentially the British equivalent of "darling" or "honey".
- Weak, but Skilled: Despite her expert firearm prowess, she still sees fit to recruit Shiki as a bodyguard on account of his superior strength.
- Wide-Eyed Idealist: She firmly believes Androids Are People, Too, and is brought to tears when she sees people and machines commit terrible acts against each other just because they don't believe friendship is possible between them.
Debut: Chapter 1
Homeworld: Excede, Sakura Cosmos
Rebecca's lifelong friend and companion, who also happens to be a talking blue cat bot. Once a regular alien feline from the planet Excede, he was rebuilt as an android—courtesy of Professor Weisz Steiner—after a near fatal traffic accident horribly maimed his body. He has long since adjusted to his robotic form, which can be converted into a pair of "Happy Blasters" that Rebecca uses to fire compressed Ether bullets upon her enemies.
- Animal Jingoism: Zig-Zagged. He seems perfectly fine with robot dogs as seen on Granbell, but "real" dogs like Nikora (supposedly) freak him out. This is in total contrast with Fairy Tail's Happy, who is freaked out by most dogs but totally fine around Plue/Nikora.
- Bathtub Bonding: Frequently shares bath scenes with Rebecca in the Spa of Eden.
- Brain Uploading: Happy's robot body is 100% mechanical, with his mind and memories transferred into it fully intact via Professor Weisz's Machina Maker after his accident.
- Catchphrase: "Aye!" and "Aye, sir!"
- Charged Attack: His Ether Bullet Full Burst technique is a powerful charged shot of Ether that leaves him exhausted afterward.
- Childhood Friends: He and Rebecca met as children living on the streets of Blue Garden, and have been inseparable ever since.
- Cloudcuckoolander's Minder: He helps Rebecca keep her feet on the ground whenever she starts acting out.
- Equippable Ally: As a robot, he can transform his entire body into a pair of Ether blasters for Rebecca to fight with.
- Expy: He is identical to Happy from Fairy Tail in name and most of his appearance (having a black-tipped tail instead of white-tipped), and the name of his home planet is a play on the original Happy's Cat Folk race, the "Exceed". The major things that set them apart is that Edens Zero's Happy is more of a Straight Man than The Gadfly, lacks the ability to fly, is a robot who can turn into guns, and is the female lead's Non-Human Sidekick instead of the male lead's.
- Funny Animal: He's a talking, perfectly civilized cat alien.
- Half the Man He Used to Be: The full extent of the damage to his original body is mostly obscured, but just enough of his lower body is shown to suggest it was totally ripped off.
- Heroic RRoD: He's left burned out after he and Rebecca perform a Charged Attack.
- Killer Rabbit: He may look like an ordinary cat, but he's really a robot who can morph into a pair of powerful Ether blasters.
- Meaningful Name: Just like his home series, Rebecca gave him the name "Happy" because that's how she felt when she met him after being alone for so long.
- Ninja Pirate Zombie Robot: He's an alien cat android who can also turn into a pair of energy guns.
- Parental Abandonment: He doesn't know what happened to his parents, but he is certain that they abandoned him at an age young enough that he doesn't know if they gave him a name.
- Ray Gun: His weapon form is a pair of blasters that fire non-lethal yet very painful Ether bullets.
- Ridiculously Human Robot: More along the lines of "Ridiculously Feline Robot"; he has a completely robotic endoskeleton, but his skin makes him look exactly the way he did before the car accident.
- Robot Buddy: He's been a Non-Human Sidekick for Rebecca for most of their lives, but he doesn't become this until after his accident and rebirth.
- Satellite Character: His entire role revolves around being both Childhood Friends and an Equippable Ally to Rebecca, with Happy getting little to no focus for himself.
- Straight Man: Happy always questions Rebecca or rolls his eyes whenever she does something strange.
- Street Urchin: Like Rebecca, he grew up on the streets of Blue Garden after losing his parents.
- Swords Set To Stun: He turns into a pair of Happy Blasters that fire Ether bullets. These can inflict injury and knock people out, but they can't kill anyone, allowing Rebecca to fire them at people's heads without worry.
- Talking Weapon: He can still communicate while in his blaster form.
- We Can Rebuild Him: Happy was reborn in a robotic body after getting run over by a drunk cargo truck driver.
Weisz Steiner (Year X442)
Debut: Chapter 4
Homeworld: Norma, Sakura Cosmos
Ether Gear: Machina Maker
An alternate version of Professor Weisz's past self who came into the present after a Chronophage ate fifty years of time from his home planet, Norma. Far from the respected scientist his future self would become, Young Weisz is a degenerate thief who steals and smooth-talks his way through life. He doesn't get along especially well with the crew, but tags along with them anyway so he can fully indulge in what the future has to offer.
- Ace Pilot: He knows his way around a spaceship, and proves to be a more effective pilot than Rebecca thanks to his ability to upgrade the Aqua Wing to his advantage in mid-flight. Elsie also commends his skill in getting past the wall of spacetime clouds surrounding Norma, though she proceeds to mock him for failing something comparatively simpler like avoiding a Tractor Beam.
- Alternate Self: He's not merely Weisz from the past, but an entirely new person from a planet whose time was stolen, which allows him to co-exist with his "future" self totally free of time paradoxes that would impact the other's life. It also means he won't necessarily become a professor in 50 years, nor is he guaranteed to live that long.
- Always Save the Girl: He springs into action when he hears a girl is in trouble. As he is a noted Casanova Wannabe, though, it's a given that he does this for less than altruistic reasons.
- Baldness Angst: When Rebecca shows Young Weisz a picture of how he'll look in fifty years, he's shocked and upset by how thin his hair will become.
- Casanova Wannabe: He fancies himself a smooth ladies' man who'll do whatever he can to get his way with them. So far, every girl he's met has been thoroughly unimpressed with him.
- Equivalent Exchange: His Machina Maker requires a pre-existing source of machinery or metal, or else there'd be nothing for him to rebuild.
- Everyone Has Standards: Although he isn't much better than the rest of his old gang of thieves, seeing how he also shares their idea of using Pino's EMP to make money, he draws the line at their callous mistreatment of her.
- Fire-Breathing Weapon: Atlas Flame, an assault rifle instantly modified into a flamethrower. Its name is also a Shout-Out to the dragon of the same name from Fairy Tail.
- Fire-Forged Friends: He initially starts off wanting nothing to do with the crew, only helping them escape from Norma so he can go on the lam, and almost selling them out to Elsie for his own safety right afterward. After coming back to introduce Homura to the crew purely for the sake of using her to model outfits in the ship's Dress Factory, he winds up unwittingly earning their trust through small acts of kindness he does along the way, and proves that he has come to care for them in his own way.
- Fish out of Temporal Water: Thanks to the Chronophage rewinding his planet's time, he's fifty years behind where he should normally be, and thus amazed and confused by all the advancements and changes he would've yet lived through.
- Former Teen Rebel: Minus the "former". Young Weisz embodies the less than model citizen Old Weisz was before his maturation, being an ex-organized crime member who struck out alone to conduct his own dirty work.
- G.I.R.L.: In the virtual world of Digitalis, Weisz decides to have some fun and makes himself a sexy female avatar with Stripperific clothing. He soon regrets his decision when he starts suffering from stiff shoulders on account of heavy breasts, and switches back to his usual appearance.
- Greed: This is a prime motivator for Young Weisz, who sees it as reason enough to steal from someone. Going by what Old Weisz tells Rebecca about how stealing is wrong, however, he appears to outgrow this later in life.
- Hidden Depths: Although he does it for perverted reasons, Weisz shows he has an unexpected eye for costume design when he makes a Asian-style Playboy Bunny outfit for Homura, who is pleasantly surprised by how much she likes it after dreading the thought of having to model for him.
- Jerk with a Heart of Gold: For all his unrepentant greed and lechery, he treats robots like Happy and Pino very well, and he grows to care for the rest of the crew as they do for each other. He does get embarrassed whenever someone calls him a good person, however.
- Kick Them While They Are Down:
- Once Sibir is beaten in the Norma arc, Weisz points his Ether gun at him and pulls the trigger without hesitation, only to find it's been accidentally disabled by Pino's EMP.
- Played for Laughs during the Mildian arc, where he viciously stomps on an Ether Gear user after rendering him helpless with Pino's EMP.
- More Dakka: His "Million Bullets" technique is Exactly What It Says on the Tin: a series of hidden turrets that mercilessly perforate his enemies with a barrage of bullets.
- Nominal Hero: While he has occasional flashes of decency, he largely looks out for his own skin, and often just helps out when he sees how it would benefit himself.
- Not So Different: Young Weisz appears to be a total far cry from his more dignified and respectable older self, but once the crew spends more time with him, they're pleased to find he still has the same kind and considerate heart behind all his scumminess.
- Pet the Dog: He shows he's much kinder than he lets on when he saves Pino from his old gang and restores her torn leg for nothing in return, and giving Happy a slight repair job from getting banged up because he "felt bad seeing him".
- Pragmatic Hero: He typically resorts to dirty tactics when he has to fight, as demonstrated during the Mildian arc, where he bends the tournament's "no outside help from friends" rule by using Pino's EMP on an Ether Gear user, whom he proceeds to vicously stomp on.
- Revolvers Are Just Better: Young Weisz carries an old-fashioned revolver in a world where people carry more futuristic-looking guns. Justified due to coming from an age decades before the present.
- Shadow Archetype: This Weisz embodies everything Professor Weisz grew beyond. Whereas the professor is charitable, caring, and charming, Young Weisz is greedy, selfish, opportunistic, and shamelessly lecherous. However, Young Weisz proves to be Not So Different from Old Weisz when he shows he cares for humans and machines deep down.
- Technopath: His Ether Gear lets him interface with machines and rebuild them instantaneously, ranging from physical repairs to upgrading ships and weapons. By his own admission, he's nowhere near the level of his older self, who could build a lifelike android body for Happy that's completely indistinguishable from his organic form.
- Toxic Friend Influence: It's implied that some of his perverted views towards women rubs off on Shiki, who gradually becomes more vocal about wanting to see girls in skimpy clothes after Weisz officially joins the crew.
- You Can't Go Home Again: His ultimate justification for joining the crew. From his perspective, he and his entire planet were irreversably thrust into a new time period. Since going back would mean cutting himself off from the rest of the universe behind a spacetime wall, or at the very least facing up to the police hunting him for being part of Sibir's gang, he realizes he can't go back to his old life and disavows Norma as a "dead" planet.
Debut: Chapter 6
A tiny "anti-bot" android who specializes in using EMP to disable technology and Ether Gear. She was built by Ziggy some time between his retirement and death to serve as the so-called "Light of Edens", but lost all memory of her past after it was cruelly erased by a gang of thugs. After being rescued by Shiki, Pino pledges him as her new master and friend, joining him to discover the true meaning of her existence.
- An Arm and a Leg: Her left leg is cruelly torn off by Sibir and replaced with a screw when she can't dance for him. Weisz later restores her leg using his Machina Maker.
- Art Evolution: Her design—namely her head, eyes, and mouth—quickly transitions from blocky and robotic to soft and more distinctly human over the course of the series. Her antennae also immediately jump from angular to ovular between the Digitalis and Mildian arcs.
- Awesomeness by Analysis: She can analyze people and their surroundings to determine their advantages and weaknesses. This gets Played for Laughs when her constant analysis of everything end up sucking all of Shiki's fun out of a sightseeing tour.
- Because You Were Nice to Me: She betrays Sibir after Shiki speaks about her like a living person who needs to be loved and cared for, not a toy to be played with and disposed of.
- Become a Real Boy: Following her experiences in a human Digital Avatar on Digitalis, Pino makes it her dream to become a human for real, believing that Mother has the power to grant this wish.
- Blessed with Suck: Her EMP has many uses that could come in handy in battle against enemies who use Ether Gear and mechanical weaponry, except it also affects her allies nearby, including Shiki and Happy, so she tends to hold her powers back unless she deems it necessary.
- Broken Bird: She was terribly abused by Sibir, who berated her, ripped off her leg, and forced her to make him her master by erasing her memories of her old one. While she musters the courage to defy Sibir, her amnesia leaves her with an existential crisis once she learns her original master is already dead.
- Characterization Marches On: Pino acts very serious and matter-of-fact when first introduced in the Norma arc, which is a far cry from subsequent arcs where she becomes more cheerful and inquisitive.
- Corrupt the Cutie: Played for Laughs when she eagerly learns from Captain Connor how to say "Screw you", which she misinterprets as "Screws for you." And that's just the Bowdlerized version by Kodansha; in Japanese, she learns to say something much naughtier:Pino: Fax you!
- The Cutie: Despite suffering her own degree of physical and emotional abuse, Pino is the most innocent and cheerful member of the crew.
- The Dog Bites Back: After all the abuse she endures as Sibir's toy, she strikes back against him by shutting down his Knight Gear before Sibir's bird can kill Shiki with it, firmly putting the gang behind her.
- EMP: She can generate relatively harmless electromagnetic pulses that disable all other machinery (electronics, robots, etc.) in an area around her for a few seconds. This can also shut down Ether Gear, including her nearby allies.
- Fairy Companion: Although actually a Robot Buddy, she evokes this image due to her resemblance to a fairy, and she becomes a trusty Sidekick for Shiki. For bonus points, she also dresses up in a fairy costume during the Mildian arc.
- Gender-Blender Name: "Pino" is a masculine name, yet it's used here for a feminine android.
- Humanity Ensues: Downplayed. She chooses a Little Bit Beastly humanoid form for her avatar on Digitalis, and takes a moment to admire her reflection when she catches a glimpse of it in a window.
- Identity Amnesia: Ever since her memory was damaged by Sibir, she has forgotten everything about her original master, Ziggy, including the purpose of her existence.
- Laser-Guided Amnesia: Sibir has her memory of her former master removed so she'd be loyal to him, though she retains her memory of her own functions.
- Living MacGuffin: Sibir holds her hostage so he can use her EMP abilities to steal military-grade robots and take over the city. Shiki and his friends want to rescue her because she's a friend who doesn't belong in Sibir's era, while Weisz wants her just to get rich off of her.
- The Needs of the Many: Downplayed. When faced with getting a group of B-Cubers off of Guilst, Pino deems it most "efficient" to abandon The Load who'd fallen behind when going back for her would endanger the group's chances of escape, and struggles to grasp Rebecca's decision to go back for her, even though they barely know each other. Once Rebecca does so, however, Pino assures her that she is happy with the outcome.
- The Noseless: Zig-Zagged. She is drawn without a nose most of the time, but there is one instance where she has visible nostrils before breaking into Tears of Joy.
- One Degree of Separation: Before her appearance in the story, she was fixed up by Professor Weisz, Rebecca and Happy's Parental Substitute. When they get in touch with him, the professor says that her original master was the Demon King who raised Shiki.
- Pinocchio Syndrome: While visiting Digitalis, Pino chooses a humanoid Digital Avatar for herself, and takes a moment to admire her own appearance in a mirror. Once she returns to the real world, she is disappointed to go back to being a bot, and shortly thereafter declares her intent to become human for real.
- Punny Name: "E.M. Pino" is a fitting name for a robotic EMP generator.
- Ridiculously Human Robot: She's an advanced android who can feel joy, fear, and sadness, and is capable of crying on all accounts. Shiki takes this as proof that she, like all other machines, has a heart.
- Robot Buddy: She becomes Shiki's Non-Human Sidekick, and is the primary Series Mascot of Edens Zero.
- Robot Girl: She's an android designed to resemble an adorable little fairy girl.
- Rose-Haired Sweetie: The "hair" in this case is actually metalic pink plates, but they reflect her overall innocence.
- Series Mascot: The latest in Mashima's long tradition of mascot characters, with her design clearly demonstrating the Science Fantasy setting of the series. Somewhat uniquely, Pino isn't introduced until a few chapters in, and was kept out of any promotional material.
- The Smart Guy: She is the most intellectual member of Shiki's field team, and is responsible for analyzing situations, devising strategies, and serving as a relay between them and Mission Control.
- Tears of Fear: After everything Sibir put her through, she gets these when she thinks about what will happen if she doesn't do as he says.
- Tears of Joy: She's moved to tears when Shiki fights Sibir for her sake and overlooks his own injuries in favor of her.
- Trapped in Villainy: In the Norma arc, Sibir forces her to designate him as her master and go along with his crimes after deleting her memories of Ziggy and tearing off her leg. Although she'd rather be with her real master despite forgetting him, she can't bring herself to ignore his orders, both because she's terrified of the further abuse she'd suffer from him, and because he'd take his anger out on other androids. Experiencing Shiki's kindness and concern convinces her to defy Sibir.
- What Is This Thing You Call "Love"?: Downplayed. She's capable of understanding the concept of friendship, and considers herself a friend of Shiki. However, she doesn't understand the actions friends take for each other when it's "inefficient", such as going back for a lost friend when it decreases the survival rate of the majority.
- Wistful Amnesia: Despite getting her old memories of Ziggy deleted by Sibir, she still knows that she can't remember him and is deeply troubled by it.
Debut: Chapter 18
Homeworld: Oedo, Sakura Cosmos
Ether Gear: Soul Blade
A young samurai in training from Planet Oedo who has the unfortunate habit of blurting out every thought that crosses her mind. She was mentored by the Four Shining Stars' Valkyrie, whose disappearance leads Homura to join the Edens Zero crew in the hope of finding her. She also sees this as an opportunity to test her own mettle by challenging the current Demon King, Shiki, to an honorable duel.
- All of the Other Reindeer: She endured just as much gossip and harassment on her homeworld for being raised by a machine as Valkyrie did just for being a machine. This factors largely into Valkyrie's decision to leave in search of Homura's real mother, since Valkyrie felt Homura deserved better.
- Always Someone Better: Although she comes across as a Master Swordswoman to her friends and enemies, and has skills no ordinary human is capable of, she is still just a student to the significantly more experienced Valkyrie, and is prone to mistakes when faced with someone stronger than her.
- Ambiguous Disorder: She shows signs of social disability often associated with Asperger Syndrome, such as a near total lack of a social filter, only mild changes in facial expressions, a slight struggle with friendly interaction, and a tendency to lose focus on other people around her when talking to one person. She is also extremely sensitive to heat, considering a bath in an ordinary hot spring to be rigorous training.
- Animal Theme Naming: Her techniques all have some kind of animal mentioned in their name:
- Leopard: Leopard Stance, Leopard Claw Frenzy
- Dragon: Dragon Flash
- Snake: Snake Strike, Snake Bite
- Antiquated Linguistics: She speaks with a formal tone like someone out of the Edo period in Japanese, which Kodansha translates into slightly medieval English.
- Badass in Distress: Very briefly during the Sun Jewel arc, where she's temporarily held hostage by Garrot and rendered helpless for insubordination while she and Shiki are sent to work in the labor district. Shiki quickly saves her before Garrot can do anything unsavory.
- Bathtub Bonding: She bathes frequently in the Spa of Eden with Rebecca and Happy, which quickly leads the two girls to becoming friends.
- Beauty Mark: She has a small one directly under her left eye.
- Berserk Button: She despises any slight or insult levied against her master, whether it's someone who calls her less than human for being an android, or a supposed replica designed to mimic every detail of her.note
- Bilingual Bonus: In Japanese, she always says "Ether" and "Ether Gear" in hiragana, the written letters for words of Japanese origin, rather than the usual katakana for loanwords.
- Blade Spam: Her Snake Strike technique is a split-second variety of this attack.
- Boobs of Steel: She is the strongest female member of Shiki's team by a long shot, and has an equally impressive bust size.
- Broken Pedestal: She is horrified to discover that her own mother—whom she spent much of her childhood waiting to return—is actually Madame Kurenai, the Evil Overlord of Sun Jewel, and the main reason why Valkyrie has been kept away for five years.
- Brutal Honesty: Her habit of voicing her innermost thoughts has led to her voicing some unflattering opinions towards people, namely Young Weisz, who is always informed of how uncomfortable he makes her.
- Character Tics: She usually covers her mouth with her sleeve whenever she's saying something that's supposed to be a secret.
- The Comically Serious: Despite her perpetually solemn face, her tendency to blurt out her thoughts for no reason lends itself to some humorous and awkward situations.
- A Day in the Limelight: She gets more focus out of anyone in the team during the Mildian and Sun Jewel arcs, which focus primarily on her past and search for Valkyrie.
- Did I Just Say That Out Loud?: While she doesn't always say so, she is wholly aware of her habit to openly say what she means to keep to herself.
- Doomed Hometown: She comes from a village that was attacked by bandits that apparently claimed her father's life. Valkyrie saved her from a trio of them who were on the verge of kidnapping her and selling her to slavery.
- Dual Wielding: Her Leopard Stance splits her sword into two short blades.
- Emotionless Girl: Downplayed. Her default expression is a distant, contemplative gaze, but she still shows emotion; it just comes across in less extreme changes than other characters, even when she becomes embarrassed or upset.
- Everything's Better with Samurai: Invoked. She admits she was going for a "knight" theme, but ended up looking like a samurai, which Shiki thinks is way cooler.
- Fatal Flaw: Her complete lack of a social filter inevitably becomes problematic when facing against enemies, who end up catching wind of her thought processes and secrets without her meaning to.
- Fantastic Fighting Style: Unlike other Ether Gear users, she has two separate style names: "Five Sword Fencing", when she has assumed her Leopard Stance; and "Warrior Maid Single-Sword Attack", when using her sword's default form.
- Friendly Rivalry: Her desire to battle and defeat Shiki is purely out of a good-natured desire for a Worthy Opponent, since they become quick friends not long after they meet each other.
- I'll Never Tell You What I'm Telling You!: Every time she says something she ought to be keeping to herself, such as her secret agendas or unflattering opinions towards others, she usually caps it off by saying she won't comment on it.
- Implausible Fencing Powers: She first demonstrates her Ether Gear's power by slicing a high-speed missile clean in half with her sword. She's also capable of Parrying Bullets from unlikely distances.
- Keigo: She speaks with a formal register in Japanese, reflected by her Antiquated Linguistics in English.
- Kimono Is Traditional: Her nigh-exclusive outfit is a kimono, which makes her stand out as the most old-fashioned looking character in a predominantly Science Fiction setting.
- Lady of War: A female samurai who wears a floral kimono and carries herself with a calm, dignified air. Using her Leopard Stance and Soul Blade, she defeats a group of armed soldiers with almost effortless grace.
- Laser Blade: Her Ether Gear gives her the power to create a katana from her own Ether, allowing it to change shape to suit her fighting style. It also has the power to momentarily transfer Ether into other people.
- Master Swordswoman: Downplayed. She has Implausible Fencing Powers that the best real-life swordsmen can only dream of having, such as slicing missiles, deflecting bullets, and single-handedly decimating groups of enemies...but she's still a young, growing student who cannot begin to compare to her mentor, and she gradually faces more challenging enemies that showcase just how much experience she still lacks.
- No Social Skills: She has certain lapses when it comes to talking to others, in part because of her habit of always speaking her innermost thoughts in public. At one point in the Sun Jewel arc, she also instinctively shouts out loud for someone who's seen her mentor in the middle of a crowded building, and continues to do so against Pino's advice until Rebecca finally admonishes Homura.
- One-Woman Army: She is such a skilled swordswoman that she can wipe out an entire squadron of trained gunmen with ease.
- Orphan's Plot Trinket: The stuffed animal she received from her mother before she left, which she was told to always hold on to so her mother could recognize her. While it has no purpose or appearance outside of a flashback, the fact that Homura was clutching it at the lowest point in her life is what inspired Valkyrie to leave to find her mother.
- Parental Abandonment: She has lost both of her parents: her father is implied to have died in the same war where she met Valkyrie, and her mother left before the war started to provide for their family, only to become the Evil Overlord of another planet.
- Parrying Bullets: She's capable of using her Soul Blade to deflect bullets back at their firers with impeccable precision, and from across great distances.
- Red Herring Mole: Homura apparently betrays the crew on Digitalis to form an alliance with Jamilov for the sake of finding Drakken Joe, calling her story about finding Valkyrie a lie and threatening to kill her "friends" if they stand in her way. Moments later, the real Homura shows up and ousts the mole as an imposter who took her place to infiltrate the crew.
- Shrinking Violet: She used to be the exact opposite of the way she is now before she met Valkyrie, being so timid that it was a struggle just to introduce herself.
- Spirited Competitor: Although she is very modest about it, she openly admits to getting excited whenever she is about to face strong adversaries. It's for this reason why she wants to fight Shiki, because to her, anyone worthy enough to inherit the title of "Demon King" from the one Valkyrie was never able to defeat must be a Worthy Opponent.
- Super Speed: Her Leopard Stance drastically increases her speed, allowing her to attack multiple enemies in an instant.
- Too Dumb to Live: Deconstructed. Her tendency to blurt out things she ought to be keeping secret in front of her enemies is not because she's dumb, but because she has a persistent social disorder. Unfortunately, making such simple, life-threatening mistakes makes her come across as rather dim to other people, which touches a nerve with Shiki.
- When You Coming Home, Dad?: Homura's mother left their planet to earn money for her family, unintentionally leaving Homura alone when war broke out and her father was killed. While Homura doesn't resent her mother for this, Valkyrie decided to bring her mom back by any means necessary when she felt Homura desperately needs a real parent's unconditional love. This is complicated when they find out her mother has since become the Evil Overlord of Sun Jewel.
- Worthy Opponent: She considers Shiki to be one, not because she's fought him personally, but because she swore to battle the "Demon King" of Edens Zero, and he's been deemed fit for the title by the last Demon King and his followers.
- Wrecked Weapon: Her Soul Blade can be broken against a hard enough surface, and will remain in a broken state when summoned until Homura has time to reforge it.
Demon King's Four Shining Stars
- The Ageless: Because they are androids, they all look exactly the same during their debut appearance as they did when Shiki was a baby.
- Breaking the Fellowship: Upon retiring, Ziggy split them up with one final order for them to each live their own lives as they saw fit until Shiki came of age. Shiki's goal upon getting the Edens Zero is to get them back together, helping them overcome the physical or emotional hurdles keeping them from doing so.
- Dub Name Change: Their name translates directly from Maō Shikōsei (魔王四煌星).
- Elite Four: A heroic example, despite what their master's title would indicate; they are state-of-the-art androids with unique functions and capabilities that, when brought together aboard the Edens Zero, turn it into one of the most formidable, spaceworthy ships in the entire cosmos.
- Gotta Catch Them All: Shiki and the gang are required to gather all four androids in order to bring the Edens Zero to full travel capacity and brave Dragonfall, a swarm of dragons that stands between the Sakura Cosmos and Mother.
- His Name Really Is "Barkeep": The descriptive titles they're called by are their primary ID codes, which are more or less the casual "names" of androids. While Sister and Valkyrie are shown to have names attached to their "titles"—Ivry and Yuna, respectively—they're treated more as surnames than anything.
- Living MacGuffin: These fully sentient androids are also Plot Coupons required to pave the heroes' way to Mother.
- Ms. Fanservice: With the exception of Hermit, the Four Shining Stars are all highly attractive, busty Robot Girls who have their share of suggestive scenes, despite having comparatively less screentime than girls like Rebecca and Homura.
- One Degree of Separation: They were all built by Ziggy on Granbell, the same planet where he retired to raise Shiki.
- Ridiculously Human Robot: Their emotional behavior is practically identical to that of any ordinary human, and they have the physical ability to cry and bleed as if they were flesh and blood. Given that their creator believed that all robots are alive in the same way that humans are, these features were likely implemented to take full advantage of that.
- Robot Girl: All four of them are built to be female, and three of them are physically attractive young women, with the fourth being a cute young girl.
- Uniqueness Value: Each of the Four Shining Stars is entirely unique and can never be fully replicated by another android. Because of this, Homura becomes downright furious when Xiaomei pits her against a training bot holographically disguised as Valkyrie and passes it off as a replica with the same memories and personality as her, as Homura views the idea of a second Valkyrie to be an insult to the original.
Debut: Chapter 14
Homeworld: Granbell, Sakura Cosmos
The "Shield of Edens", tasked with defending and maintaining the Edens Zero. She is completely subservient to her master, the Demon King, and follows his orders without question. Witch is the only Shining Star to remain aboard the ship after Ziggy's retirement, dutifully waiting for Shiki's return and succession as Demon King.
- Absolute Cleavage: Her more traditional Hot Witch costume features nothing but a pair of sashes covering her chest, leaving everything in between and around them completely bare.
- Berserk Button: She rarely shows any anger, but the one thing guaranteed to set her off is going into an unauthorized part of the Edens Zero.
- Cleavage Window: Her first outfit features a cut in the upper center that exposes quite a bit of her well-endowed chest.
- Does Not Like Shoes: She remains barefoot at all times.
- Even the Girls Want Her: Witch's face is so beautiful that when she unmasks herself for the first time, Rebecca and Homura are just as captivated as Shiki and Weisz.
- Flat Character: She's one of the less developed members of the Four Shining Stars, as her personality revolves around her willing subordination to the Demon King.
- Happiness in Slavery: Downplayed. Only Witch considers herself to be the Demon King's property due to her status as an android, which Ziggy and Shiki heavily discourage. Nevertheless, she is at her most content when following her master's wishes, no matter what her personal feelings may be. It's also indicated by Ziggy's orders for the Four Shining Stars to live their lives as they see fit that her subservience is entirely her own choice.
- Hot Witch: Her android body is very shapely, and she wears a dress which reveals a lot of leg and cleavage. For extra measure, she switches out her usual outfit with a classic wizard hat and staff during the voyage to Mildian.
- Magitek: Fittingly for someone called "Witch", she employs some manner of magic energy when purging the Edens Zero of its parasite infestation.
- One-Way Visor: For her initial outfit, the entire upper half of her head is covered by a helmet with a black visor, with only one of her eyes becoming visible when she expresses dread.
- Sarcasm-Blind: She follows each and every kind of order Shiki gives her to the letter without question, including his joking order to bark like a dog, much to his disturbance.
- Spaceship Girl: Unlike the other Shining Stars, Witch is networked directly into the Edens Zero's mainframe at all times, essentially making her a part of the ship and allowing her access to its defense and surveillance systems. As such, despite having no physical connection to the ship at all times, she is unable to leave it.
- Surveillance as the Plot Demands: A benign example. As she is connected with the Edens Zero, she is capable of hearing every conversation on the ship as she pleases, and provides advice as necessary.
- Tranquil Fury: On the rare occasions when she gets angry, she remains just as calm as always, but with a terrifying Death Glare.
- Vapor Wear: Her first outfit's Cleavage Window indicates she has no bra; her second outfit's Absolute Cleavage confirms it.
- You Gotta Have Blue Hair: Her hair is colored green.
Debut: Chapter 24
Homeworld: Granbell, Sakura Cosmos
The "Life of Edens", a crude-mouthed nun with the miraculous ability to heal wounds and repair broken machines, including the Edens Zero itself. She wound up having her identity stolen by another android for ten years after getting caught during a mission to the planet Guilst, leading to some confusion until the real Sister is finally rescued.
- Anger Born of Worry: Sister gets Hermit to take responsibility for nearly getting the ship destroyed while she was acting like Achilles in His Tent, despite knowing that she was still deep in a Heroic BSoD at the time. However, Sister makes it clear soon afterwards that she was concerned the whole time and is just happy to have her back.
- Battle Strip: She takes off all her clothes when activating her healing powers on Illega's petrified victims, revealing a bikini-like body pattern. Lampshaded when a flabbergasted Shiki wonders what the point of it was, while Weisz flat out doesn't care.
- Berserk Button: Her biggest pet peeve is when someone tries pushing the button on Mosco's belly, especially Mosco himself.
- Big Sister Bully: She has this sort of dynamic with Hermit, whom she teases often and gives a harsh scolding whenever she causes trouble. That said, Sister has no ill will behind it and genuinely loves Hermit like the others.
- Chubby Chaser: While not romantic, she keeps Mosco around because she thinks he's adorable, despite verbally putting him down 95% of the time.
- The Dog Bites Back: She's in no mood to listen to excuses when she's freed from her imprisonment in Rogue Out's basement and finds that Rogue Out's leader has been using her powers and name to build her own reputation for ten years, taking the imposter down in a matter of moments.
- Flat Character: Like Witch, Sister is less developed compared to the other Shining Stars, since she only plays a minor role in her own introductory arc and sticks to a supporting role thereafter.
- Good Is Not Soft: She's extremely unforgiving to her imposter for thinking she can get away with impersonating her for ten years, first threatening to remodel her into one of the Demon King's latrines, and then promising to break and fix her endlessly until she tires of it. She only spares the imposter once Weisz tells Sister to lay off and focus on escaping the then-doomed planet.
- Jerk with a Heart of Gold: She's crass and makes fun of everyone in the crew, including her new master, but she's also a dedicated healer and admires Shiki's friendliness.
- The Lad-ette: She is an Ore Onna who has a crude mouth, beats the crap out of anyone who slights her, and gets excited when stuck in the middle of life-threatening peril.
- The Medic: Her role as the "Life of Edens" amounts to this, as she can magically heal both humans and machines, including the Edens Zero itself. However, her powers can only work on "living" things, and the ship technically isn't "alive" until all Four Shining Stars are present.
- Mystical White Hair: Her hair is silvery white, and she has mystical healing powers despite being an android.
- Nun Too Holy: She dresses like a nun, but talks like a thug and strips down to her skivvies to cast her magic.
- Ore Onna: She refers to herself with the almost universally male Japanese pronoun ore, sounding extremely butch.
- Shameless Fanservice Girl: She performs a Battle Strip when using her powers, seemingly for no reason at all and not caring what anyone around her things.
- Unwanted False Faith: She doesn't give a damn when her imposter claims to have always revered her as a god for her healing powers, as she doesn't take kindly to being taken hostage and impersonated for ten years.
- Walking Techfix: Her healing powers work not just on organic beings, but broken machines as well. However, it only works on a physical level, and only if the machine in question is "alive".
- White Mage: Her powers revolve around healing and restoration of any living thing, whether they are organic or mechanical. Her powers also work on petrification, as she demonstrates when she revives all of Illega's stone victims.
Debut: Chapter 29
Homeworld: Granbell, Sakura Cosmos
The "Mind of Edens", an ace programmer and gamer who manages the ship's security systems. She is found in the virtual world of Digitalis following a traumatic incident on Planet Newton that left her with a seething hatred of humans, but Shiki's kindness inspires her to come out of isolation and learn to trust her new human crew.
- Achilles in His Tent: She resists Shiki's attempts to bring her back to the Edens Zero in favor of remaining on Digitalis, which she owes to her distrust of them. When she finally relents, she just holes herself up in the Dress Factory when the ship comes under attack by Spider, telling everyone to go without her. She only comes around after Shiki and the others help her realize that she wants to trust them, but can't trust herself after humans used her to destroying a planet of androids.
- Big "NO!": Shrieks out a chilling one during her backstory when she witnesses Planet Hook suffer an Earth-Shattering Kaboom before her very eyes after getting blasted by the Ether Accelerator she helped Newton's scientists build.
- Break the Cutie: She suffered horrifically at the hands of malicious humans she thought were her friends, leaving her in a fifteen-year Heroic BSoD of neverending anger and self-loathing, simply because she wanted to do something nice for them.
- Broken Bird: She was once a Cheerful Child who dreamed of being friends with humans, but her love for them was shattered after getting manipulated and abused in the most horrific ways, leaving her bitter, hateful, and distrusting of everyone she meets. Thanks to Shiki, she eventually recovers enough to regain her smile and sense of fun, but still retains something of a cynical streak.
- Broken Pedestal: She calls Ziggy a liar for his creed that both humans and machines have hearts, as her life experiences have convinced her that the former certainly don't. It becomes a Rebuilt Pedestal after she finally meets humans unwilling to take advantage of her (i.e., Shiki and his friends), which allows her to see the meaning behind Ziggy's words.
- Broken Tears: As Spider is destroying the Edens Zero, she just curls up in the Dress Factory and cries, too deep in self-doubt and denial over how kind the crew has been to her to do anything. The fact that the crew refuses to leave her despite her telling them to leads to the emotional breakthrough she needs to go back to her old, cheerful self.
- Cheerful Child: Her pre- and post-Broken Bird personality is a cheery and helpful girl who loves playing games and making costumes in the Dress Factory.
- Cry Cute: She fails to hold back her tears when her cynical facade crumbles and openly shares her deeply broken heart to the crew for the first time, realizing she wants to be their friend despite everything that happened to her.
- Cynicism Catalyst: Ever since she was used as a pawn and guinea pig for humans' horrific experiments for two years, she became deeply disillusioned with the idea of humans having hearts and being friends with robots. Meeting Shiki and his crew, however, has the opposite effect.
- Dark and Troubled Past: Her initial distrust of the crew and hatred of humanity is fully understandable once her past is revealed. After leaving the crew fifteen years ago, Hermit was approached by a team of human scientists on Newton who acted like they supported human-machine relations, but were secretly a group of Evil Luddites who tricked her into helping them build a Doomsday Device, which they used to destroy a planet of robots. The only reason they let Hermit live was to serve as a lab rat, resulting in two years of hellish torture until they were finally arrested and/or killed by the military, leaving her dead on the inside.
- Dull Eyes of Unhappiness: She sports these during her Heroic BSoD as an indicator that her heart and mind have been damaged by her horrific past. They light back up when she slowly but surely begins to return to her old self.
- Expy: Hermit bears an almost identical appearance to Hatsune Miku, with the same style and color of hair, a similar outfit, and a headset. For bonus points, the nickname Rebecca gives her in Japanese, Hami-chan, is a shorthand version of Miku's full name.
- Facial Markings: She has a pair of red lines shaped like whiskers on her cheeks. They turn pale when she's in the middle of her Heroic BSoD, and go missing entirely in some panels.
- Gamer Girl: She is a reported fan of the MMORPG Rogue Fantasia, where she has hidden herself away by the time the crew find her.
- Headphones Equal Isolation: She always wears a headset, reflecting her status as The Hermit.
- The Hermit: "Hermit" is her actual name, guys. And true to that name, she's first found far away from all society both in the real world and on Digitalis, and typically enjoys activities that involve holing herself away to play games.
- Heroic BSoD: She spends the bulk of the Digitalis arc—and the past 15 years—in the middle of one, having lost her "heart" after suffering severe psychological trauma at the hands of humans, and completely giving up on life in general. This makes it all the more difficult to get Hermit to rejoin the crew, but they manage after finally getting her to open up and talk about her problems.
- Hollywood Hacking: Once she's given access to a computer's data, she has complete freedom to manipulate it however she wants with just a few keystrokes.
- Humans Are the Real Monsters: Although she comes around after meeting Shiki and his friends, she is introduced despising humans and any machines who sympathize with them, believing that humans have no hearts after witnessing and suffering from their cruelty firsthand. Namely, getting manipulated by seemingly kindhearted humans into helping them obliterate a planet full of robots, and subsequently being made into a test subject.
- Hypocrite: Despite being an android who knows how poorly machines are treated, she doesn't see the point in worrying about the fully sentient video game characters on Digitalis when they're put in danger, since they're "just data". She's immediately taken aback when Shiki argues that they're alive because they can still think and feel like anyone else, which persuades her to help save them.
- In-Series Nickname: Rebecca gives her the nickname "Hermy" (Hami-chan in Japanese), which Sister finds extremely weird.
- Little Miss Snarker: She's usually a Cheerful Child, but she has something of a sarcastic streak whenever she's in a bad mood.
- My Greatest Failure: Beyond despising humans for their cruelty towards her and other machines, the reason she refuses to help the crew is because she feels responsible for the destruction of Planet Hook, which the human scientists she befriended blew up with the Ether Accelerator cannon she helped them build, rather than save it like the cannon was designed to do.
- No Good Deed Goes Unpunished: Hermit's two years of suffering and thirteen subsequent years in a Heroic BSoD all began when she volunteered to help a team of human scientists and their robot partners save a dying bot planet, only to unwittingly help them destroy the planet instead and get used as a lab rat.
- Not Afraid to Die: Has this mindset during the Digitalis arc, having completely given up on living after the horrible things humans did to her in the past. She thus doesn't react when a horde of monsters attacks her, saying it's better than getting killed by humans, and tells the Edens Zero crew to just abandon her and the ship when it comes under attack by Spider.
- Older Than They Look: She has the physical appearance of a preteen girl, but she's actually older than Shiki and his friends, on account of being an ageless Robot Girl.
- Playful Hacker: Regardless of her mood, her manner of hacking always comes with a style of childlike mischief, such as turning Shiki into a Kaiju when he's fighting Jamilov/Spider, or trolling Spider by threatening him with a switch to the ship's long-range cannons (actually a fireworks switch).
- Pride: While she's ordinarily a sweet girl, she aso has a very high opinion about herself when it comes to hacking and programming, especially around those who think they're her superior, and deems the Edens Zero's security to be airtight so long as she's on board.Hermit: No radar will ever find this ship.
Weisz: (smirking) You're awfully confident.
Hermit: (smirking back) Who do you think I am?
- Rapunzel Hair: Her hair is styled in twintails that reach down past her waist.
- Restored My Faith in Humanity: Double Subverted. Shiki's kind and selfless acts towards her and the digital people of Digitalis initially push her further into denial about humans, as she struggles to reconcile the idea of a kind-hearted human after being exposed to nothing but the ugly side of humanity. It's only when Shiki and Rebecca help her realize that she still wants to be friends with them deep down that she finally brings herself to trust and love humans again.
- Teeth-Clenched Teamwork: She begrudgingly sets her hatred of humans aside to team up with Shiki's crew on Digitalis to get rid of Jamilov, though she has no issue doing anything that would result in anyone in the crew getting banned. This ends when she ultimately becomes their friend.
- Took a Level in Cynic: A former Wide-Eyed Idealist towards humans who was exposed to the horrors humanity is capable of would certainly do this. Deep down, however, she knows humans aren't all as horrible as the ones she met, which helps Shiki restore some of her old idealism.
- Troubled Fetal Position: Her default body position during her Heroic BSoD, both in the real world and on Digitalis.
- Unwitting Pawn: She was one for the scientists of Planet Newton, whom she helped complete an Ether Accelerator designed to provide energy for the dying robot planet Hook. They never told her that they would use said accelerator as a Doomsday Device meant to destroy the planet via Phlebotinum Overload.
- Used to Be a Sweet Kid: She's introduces in an angsty and bitter state due to her Dark and Troubled Past instilling her with a hatred of humans, a far cry from her sweet and chipper personality in flashbacks. After finally opening up to the crew, she goes back to her original sweet personality, though not without a bit of a sarcasic streak.
- What the Hell, Hero?: Downplayed. Although most of the crew doesn't blame Hermit, Sister gives her a hard time for choosing to sulk when the ship came under attack by Spider, nearly resulting in their deaths, despite knowing that she'd been through a lot of hardship and had much to process. However, Sister only tells her this because she was worried for her, and Hermit apologizes to the crew for giving them all such a hard time.
- When She Smiles: Witch comments that she has the most beautiful smile, and is deeply saddened to see it replaced with a sullen and angry frown from her poor experiences with humans. Almost inevitably, she gets her old smile back once Shiki and his friends help restore her faith in humanity.
- You Gotta Have Blue Hair: Her hair is sky blue.
Debut: Chapter 39
Homeworld: Granbell, Sakura Cosmos
Ether Gear: Soul Blade
The "Sword of Edens" and Homura's mentor, whom Homura inherited her Soul Blade from. Valkyrie went missing for five years amidst growing concerns on Oedo over her relationship with her pupil. She is eventually found on Sun Jewel, where she leads a revolution against the tyrannical Madame Kurenai for reasons that are tied deeply to Valkyrie's departure.
- All of the Other Reindeer: Apart from Homura and an understanding magistrate, the people of Oedo have a generally negative view of Valkyrie for being a machine, let alone one who raises a human girl as if she's the girl's mother, while those who can look past this still see her as an irresponsible caretaker. Valkyrie can put up with it just fine on her own, but it's when the people's prejudice starts to negatively reflect on Homura that she feels troubled by it.
- Ambiguously Brown: She has tan skin, but given that she's an android, it likely means nothing about her ethnicity.
- Badass Teacher: She mentored Homura in her Ether Gear, which turned Homura into the budding Master Swordsman she is today.
- Broken Ace: She is one of the greatest fighters of Ziggy's crew, and a source of great inspiration to Homura, but she also secretly feels inadequate to be Homura's mentor, largely influenced by prejudice from a society that could never fully accept a robot like her raising a human, let alone someone who isn't her own flesh and blood.
- Cool Teacher: Homura admires Valkyrie and her teachings very much, despite not seeing her in five years.
- Gone Horribly Right: Valkyrie is the one who encouraged Homura, a former Shrinking Violet, to use her words more in the first place. She never anticipated that Homura would completely lose her social filter in the process.
- Hero with Bad Publicity: The people of Oedo are largely an Untrusting Community towards Valkyrie for her rough and violent nature, despite her efforts to settle the war on their planet.
- I Want My Beloved to Be Happy: A familial example with Homura. She realizes that continuing to raise Homura would only lead to problems, since society on Oedo frowns upon the idea of robots rearing humans and people rearing non-blood relatives, leading Valkyrie to search for her real mother. Unfortunately, Homura's real mother is also evil as sin, and Valkyrie spends the next five years trying to stop her.
- Laser Blade: She uses the same form of Ether Gear as Homura, creating an Ether broadsword rather than a katana.
- Master Swordsman: Her mastery of the sword is so great that Homura—a One-Woman Army capable of slicing missiles and parrying bullets—struggles to beat a training robot copying Valkyrie with less skill and power than the real one.
- Parental Substitute: Deconstructed. Although they don't view each other as mother and daughter, Valkyrie is the closest thing Homura has to a parent, since Homura's real mother left and her father was killed. However, the constant reminder that they aren't blood-related—especially on a planet that's largely prejudiced against machines raising humans—causes Valkyrie to feel unfit to care for Homura, leading her to search for her real mother. This ends far more disastrously than intended when she discovers that Homura's mother, Madame Kurenai, is an Evil Matriarch.
- Poor Communication Kills: Valkyrie left Homura a note that fully explained her reasons for (temporarily) leaving, and was mortified when Xiaomei informed her that the note was snatched by a neighborhood cat before Homura could find it. If Valkyrie didn't vastly underestimate how long she'd be gone for, she could have spared Homura five years of searching and wondering why her beloved master vanished seemingly without a word.
- Rebel Leader: She leads La Résistance against Madame Kurenai on Sun Jewel, which is heavily implied to be why she hasn't returned to Homura in five years.
- Tomboyish Ponytail: The warrior of the Shining Stars, and also the only one who arranges her hair into a ponytail.
Debut: Chapter 18
Sister's overweight android minion who performs various odd jobs around the ship. He was once reprogrammed into a member of the mercenary squad Rogue Out before Sister restored him to his original self.
- Ascended Extra: Very quickly goes from a one-shot villain to a tertiary Series Mascot by the end of the arc he was introduced in.
- Brainwashed and Crazy: The fake Sister reprogrammed him into joining an infamous mercenary group.
- Don't Touch It, You Idiot!: He has a button on his navel labeled "DON'T PUSH", which he tries pushing on numerous occasions. It's unclear what it would do if pressed, except that Sister gets incredibly peeved whenever he or anyone else makes the attempt.
- Flight: He has the ability to fly...by rapidly thrusting his arms into the sky. Illega's men question the physics that make this possible.
- Gonk: He has a box-shaped head and a fatty frame that's wider than two averaged-sized people standing next to each other.
- Good All Along: He initially appears as a member of the fake Sister's mercenary squad, Rogue Out. After getting shot up by Weisz, he's repaired by the real Sister and goes back to being the friendly robot he always was.
- Good Costume Switch: He goes from a Walking Shirtless Scene to wearing a business suit that hardly fits him after returning to the Edens Zero crew.
- Harmless Villain: Apart from kidnapping a similarly Gonk girl for human trafficking, Mosco poses no threat as a Rogue Out member, and gets shot up by Weisz without putting up a fight.
- Pungeon Master: He's prone to using phrases that allude to his own fatness in the English translation, such as calling Rogue Out "heavyweight knights" and saying the similarly chubby B-Cuber Couchpo is "massively adorable".
- Series Mascot: Mainly serves as a lesser mascot behind Happy and Pino, the main mascots.
- Verbal Tic: He says the word "Moscoy" or some variation thereof, usually as a figure of expression, almost to the point of PokémonSpeak. In Japanese, he ends his sentences with "gowasu" whenever he does speak normally.
- Visual Pun: His belly button is an actual button on his belly.
- Walking Shirtless Scene: He goes completely shirtless as a Fan Disservice during his time with Rogue Out.
Debut: Chapter 49
Homeworld: Aoi Cosmos
A mysterious space captain from the Aoi Cosmos that the Edens Zero crew bring aboard their ship.
- Accidental Pervert: He climbs into the Spa of Eden with Rebecca and Homura not because he's a pervert, but because he saw Happy with them and assumed it was a mixed bath. Rebecca kicks him into the air and boots him out for his error.
- Ace Pilot: Connor shows he has real piloting chops by flying the Edens Zero straight through a hazardous debris field none of the ship's crew would dare to enter, all without a single bump or scratch. The fact that the crew didn't notice his death-defying stunt shows just how much of a cakewalk he made it seem.
- Antiquated Linguistics: He speaks with a formal and archaic register in Japanese, and uses the antiquated pronoun wagahai.
- Badass Grandpa: He appears to be middle-aged at the youngest, but despite his age, weight, and mannerisms, he remains one of the finest warship pilots the Edens Zero crew has ever seen.
- Bunny-Ears Lawyer: He is a pompous man of many oddities and poor habits who grates the crew's nerves, but he's also a bona fide Ace Pilot when he puts himself behind the helm of the Edens Zero (with or without the crew's permission).
- The Captain: He was in charge of his own ship before falling overboard and getting picked up by the Edens Zero. By some strange twist of fate, his old ship is known as the Edens One, and he has piloting skills to match Demon King Ziggy, the Edens Zero's original captain.
- Crouching Moron, Hidden Badass: He looks and acts like a pompous and self-entitled oaf most of the time, but when he puts himself at the helm of the Edens Zero, he proves to be an Ace Pilot whose skills astound the Demon King's most experienced crewmates.
- Dirty Old Man: Downplayed. He admires Rebecca and Homura's beauty, and ends up sharing a bath with them because he mistook it for co-ed, but he makes sure they know he isn't hitting on them and always keeps his distance—not that this makes them any more comfortable.
- Going Down with the Ship: He certainly tried doing this when he lost his old ship, evidenced by the fact that the Edens Zero crew finds him still clutching his ship's wheel while drifting in space.
- Insistent Terminology: He insists that everyone call him "Captain", including those who aren't part of his crew or who'd otherwise contest his rank.
- Talk Like a Pirate: Kodansha's translates his Antiquated Linguistics in Japanese by making him talk like a sophisticated sailor.
- Sophisticated as Hell: Despite his formal manner of speaking, he isn't afraid to swear like a sailor, such as when he teaches Pino how to say "Screw you"—a Bowdlerization of what they say in Japanese. On a lighter note, he also teaches her how to flap her lips like a horse.
- Sesquipedalian Loquaciousness: He slips into this when he finds himself starving, telling the crew his stomach is "beset by extreme emptiness".
