Dragon Keepers in General

"We are...the Dragon Keepers!"

The 5 Dragon Keepers who protect Earth from the alien Invaders of the Evil Kaijin Army. Following the defeat of the Evil Kaijin Army's top Executives, the Dragon Keepers have been putting on a show for the past 12 years by constantly beating down the Invaders' immortal footsoldier Dusters before large audiences to show that the Dragon Keepers are forever there to keep humanity safe.

However, it's made quite clear early on that these "heroes" protecting humanity aren't the greatest of people beneath their ranger uniforms. Thus, making Footsoldier D's objective to eventually defeat the Dragon Keepers all the more necessary.

---

• Broken Pedestal: They become this big time to the populace in Chapter 88, to the point where even the Sunday battles end up being cancelled and many of their subordinates, most of them being from Red Battalion, desert en masse.
• The Chosen People: Shinya mentions throughout history there have always been people capable of wielding the Dragon's divine power with the Keepers being no exception.
• Corrupted Character Copy: Of Super Sentai teams in general, playing up the worst traits or being the opposite of each color.
  • While Red remains in the leader position, Red Keeper's heroism is fickle at best and is largely an outlet for his Blood Knight tendencies.
  • Blue Keeper maintains the public appearance of a Red Oni, Blue Oni dynamic with Red Keeper in public as he remains cool and quiet but is actually an ill-tempered Sir Swears-a-Lot.
  • Green Keeper comes off as the boisterous, silly member of the group during the Sunday battles but is a serious workaholic when out doing his real job.
  • Yellow Keeper does not fill the role of The Big Guy, instead being the brains of the group.
  • Pink Keeper plays up the role of being The Heart of the team for the camera but in actuality is aloof and only has eyes for her brother.
• Colourful Theme Naming: As expected from a Sentai team really. The Red Keeper is Akabane, Blue Keeper is Aoshima (this also extends to the previous Blue Ranger as they are relatives) and Pink is Sakurama.
• Heroism Won't Pay the Bills: Not only do the Dragon Keepers have salaries but they're also apparently on par with the average office worker's. Souma estimated since the Keepers are effectively always on the clock, they practically make less than minimum wage on an hourly basis.
  • Chidori mentioned private sponsors are the backbone for a Keeper's finances as without any he's stuck paying a 10-year loan for his new car.
• Immortal Breaker: The 5 Dragon Keepers are wielders of powerful weapons invented specifically for them known as the 5 Divine Tools. Such trump card weapons allowed humanity to defeat the Invaders as the 5 Divine Tools are capable of damaging and killing beings that were thought to be immortal. Replicas of these 5 Divine Tools were then created for the lower batallion rangers in order to give them a means to damage the immortal as well.
• Instant Costume Change: As long as a Keeper has their Divine Tool, they're able to instantly suit up. Red Keeper loses this ability with his Tool when D swipes it from him, so he has to manually put his clothes on. He doesn't seem to mind, anyway.
• The Leader: While Sosei's the overall leader of the Dragon Keepers due to his #1 ranking amongst all rangers, each of the Dragon Keepers serve as the leader of the ranger battalions of their respective color.
• Legacy Character: The title of "Keepers" can be passed down to successors and considering the known rangers look fairly young odds are they're not the same group as the one who fought the original invaders 13 years ago. So far only the previous Blue was shown through a flashback. As it would turn out, they were assuming the roles of a super sentai-themed TV show that originally ended almost seven years before the Invaders had even arrived.
• A Lighter Shade of Black: While the Dragon Keepers consist of morally twisted fame junkies, con artists, and murderous sociopaths, they're still arguably better than the Executives who work to obtain world domination however they can and see their own minions as nothing but expendable pawns.
• Pretender Diss: Yakushi calls them out for being nothing but knockoff wannabes and such a disgrace to the original Dragon Keepers that no real fan of the Tokusatsu Edition would ever accept them.
• Secret Identity: Though they make constant media appearance, they all keep their identities a secret aside from Sosei as he's simply that much of an Attention Whore. As of chapter 88, their faces are all known to the public as a sign of trust.
• The Team: The 5 of them are usually seen fighting as a team, particularly during the show matches against the Footsoldiers. In chapter 5, the five of them appear together when they confront D during his theft attempt to steal away Red Keeper's Divine Tool.
• Villain with Good Publicity: The group has enslaved the survivors of an alien race, and forced them to play as villains for the public so that they can be seen as heroes by the public, who still believe they're being invaded and saved every Sunday by them. No longer the case as of Chapter 88 thanks to Sosei being tricked into revealing his true colors to the public, to the point where several Rangers desert the organization en masse and the Sunday battles end up being cancelled.

The Five Dragon Keepers

Red Keeper / Sosei Akabane

Voiced by: Yuichi Nakamura

"We're the good guys!"

The First Class Dragon Keeper of the Red Battalion, and overall leader of the Dragon Keepers. Born Soshi Abakane, Sosei is a handsome man with unparalleled charisma and is the main public figure of the Rangers. He claims to fight for justice and against the Evil Kaijin Army but harbors an extremely twisted view on what justice really is. He originally carried the Sword Divine Tool before it was stolen by Yumeko and D.

---

See his page for tropes relating to Sosei.

Blue Keeper / Keisuke Souma

The former Junior First Class ranger of Blue Battalion. Souma had retired from the Ranger Organization for a time before being dragged back to act as Blue Keeper.

---

• 0% Approval Rating: His subordinates didn't seem keen on waiting for him to suit up, dismissively saying they'll be going on without him.
• A Day in the Limelight: Chapter 98 is almost entirely focused on him, which delves into his Backstory as a member of Blue Battalion.
• Always Someone Better: Towards Shougo.
• An Ice Person: Souma's divine tool can encase anything and everything in ice. Even Executives are helpless from being frozen solid.
• Arrogant Kung-Fu Guy: As Rikuto's JFC, he was brash and convinced himself following Rikuto's retirement he would succeed him as Blue Keeper.
• Bare-Fisted Monk: His divine tool of choice during his JFC days was a pair of spiked brass knuckles.
• Colorful Theme Naming: "Keisuke Souma". "Sou" means "azure", a type of blue.
• Fallen Hero: A non-evil example. His ego took a major hit after Rikuto's son was chosen to succeed him as the next Keeper despite Souma undergoing the Dragon Keeper surgeries. Shougo's blunt personality would frequently clash with Souma's until it culminated with their battle against Andrega where Souma came to terms with the fact he'll always be second fiddle. It's implied not long after that Souma resigned from the Rangers and became a convenience store cahsier.
• Only in It for the Money: Played With. Souma has a genuine disdain for being a Ranger again, never mind being one of the Keepers, and says the salary is awful despite the long hours and health risks. However he's not entirely above it as he had to negotiate with the Footsoldiers to make a Staged Shooting of Hwalipon personally attacking the city all so Souma could get a bonus since he claimed money is tight for him this month. Even when the entire city is at risk of being overrun by monsters he complains about how they're not getting paid for it.
• Refusal of the Call: Claims Blue Battalion has been trying to pull him out of retirement in order to replace the deceased Blue Keeper. He eventually agrees to make one appearance for the Sunday battle, though it seems his fellow Keepers won't let him get away after that,
• Retired Badass: Previously the Junior First Class of Blue Battalion, though his retirement doesn't last for long as he's eventually dragged back to be the new Blue Keeper.
• Screw This, I'm Outta Here: Tries to pull this following Blue Keeper's return to the Sunday Battles. Apparently he was only to play Blue Keeper for the one time but the other Keepers reneged on the agreement as there's another role he needs to fill.
• Took a Level in Cynic: After Blue Keeper was credited for slaying Andrega, what remained of his ego as the JFC of Blue Battalion was shattered as he came to terms he'll always be second best to Blue Keeper.
• Took a Level in Idealism: Despite his own self doubt, he regained the resolve to stand and fight against the Executives as its something Shougo would have wanted.

Yellow Keeper / Shinya Kiritani

Voiced by: Kensho Ono

"C'mon, keep your act together. Nobody asked for your opinion."

The First Class Dragon Keeper of the Yellow Battalion, and Yumeko's boss. A man who's always showing a cheeky smile, no matter the situation. Relaxed and with an easy-going attitude.

---

• 24-Hour Armor: In contrast to the rest of the Keepers, Shinya tells the new recruits that he never takes his suit off, just in case of an emergency. It took 88 chapters just to see his face.
• A Day In The Lime Light: After appearing multiple times in rather minor scenes, Yellow (and his Battalion as a whole) is center focus of Chapter 84.
• Aloof Archer: Fitting as he's the brains of the Keepers, has a slim figure, and maintains a cool, if somewhat smug, demeanor at all times.
• Big Bad: The mastermind behind the Kaijin War as Shinya created the Executives.
• Cheshire Cat Grin: His perpetual smile leans into this territory after Yumeko exposes the involvement of Yellow Battalion in past experiments that lead to the creation of the Monsters.
• Everyone Calls Him "Barkeep": Always referred to his title by both subordinates and his fellow Rangers, even in casual seting.
• Evil Genius: Leader of Ranger R&D as the head of Yellow Battalion, and involved in the experiments that created the Monsters which are heavily implied to be mutated people.
• Keeping the Enemy Close: After meeting D following the Time Skip, Shinya seems keenly aware that he's taken on Hibiki as a disguise as he's introduced with his Divine Tool in hand and jests it was unnecessary to bring it after he couldn't provoke D.
• Luke, I Am Your Father: Revealed to D in Chapter 96 he created the Executives, therefore creating D by extension.
• Mad Scientist: Of the Mad Biologist variety. Yellow took part in the experimentations that created the monsters Hwalipon has been using to terrorize the civilian populace and previously the Executives themselves.
• Magnetic Weapons: Though his divine tool appears to be a bow, at full strength its more akin to a gauss cannon.
• Maker of Monsters: Experiments in Yellow Battalion created the Monsters. It would later be revealed that prior to the Kaijin War he created the Executives as well.
• Man Behind the Man: Though Sosei presents himself as the leader of the Rangers Association, Shinya is its real mastermind as he's responsible for creating the Human-Invader conflict as he created the Executives and the Divine Tools to fight them.
• Older Than He Looks: Like Sosei, he was a member of the TV production of the Dragon Keepers. Unlike him however, Shinya was seemingly never replaced by clones so he's looked the same for nearly two decades.
• Perpetual Smiler: He's always seen with a smiling expression, even when Yumeko is blackmailing him with information that would suggest Yellow Battalion had a hand in the creation of the monsters.
• Psychotic Smirk: His usual grin turns even more unsettling when D confronts him about the Divine Tools being made from human remains.
• Resemblance Reveal: Upon removing his helmet with the other Keepers in Chapter 88, it is revealed he bears a very strong resemblance to Yumeko. Namely the blonde hair and Dull Eyes of Unhappiness. Seems to only be a skin deep resemblance as his full name is revealed in Chapter 91, indicating no familial ties to her.
• The Reveal: He officially reveals to D in chapter 96 that he was the one behind the creation of the Invaders.
• Rival Science Teams: With the former Yellow Battalion JFC Daidai, though it seems to be a one-sided affair. At the very least Shinya knows Daidai's work when he sees it even if it's sloppy.
• Soft-Spoken Sadist: His voice never seems to go above his nature timbre, and he's unfailingly polite to D even when he admits his experiments resulted in the creation of the Invaders and the Divine Tools.
• Team Killer: Doesn't hesitate to catch his Yellow Battalion subordinates in the crossfire of an attack in order to bring down Andrega.
• Uniformity Exception: His Divine Tool is named after the World Serpent Jörmungandr of Norse Mythology while other Divine Tools being named after Japanese deities.

Green Keeper / Chidori

Voiced by: Kosuke Toriumi

"Gahahaha! What a dumbass!"

The First Class Dragon Keeper of the Green Battalion. A loud and eccentric man who enjoys interesting things, and the only Keeper who has their entire face covered while transformed. Outside his ranger suit, he puts on an act as a mysterious civilian informant who provides useful information for members of Green Battalion.

---

• Animal Motifs: As Chidori, Green Keeper is heavily associated with lizards and reptiles. All of his Information Broker's Tools have a gecko embalzoned on its surface.
• Attack of the 50-Foot Whatever: On top of being able to control the size of his divine tool, it also lets his body grow in size so he can tower over even the biggest Executive Todomask.
• Because You Were Nice to Me: Tells D he spared him because of the time D vouched for him when he was being accused of being an Invader by the police, though a case could also be made for the comradery they had during the Dreamy School Life arc while D was unaware that Green knew his secret.
• Boisterous Bruiser: In-costume, Green is a jolly fighter aching for a proper opponent. While he acts arrogant on the field, his ego hides concern for his underlings.
• Brutish Character, Brutish Weapon: His "character" as Green Keeper is a loud, egocentric warrior itching for a fight, and his Divine Tool comes in the form of a large two-handed hammer.
• Clark Kent Outfit: His civvies are long and baggy, making him look a bit gaunt. When he's in his skin-tight Keeper suit, he's totally ripped.
• Cool Car: Has a preference for driving vintage cars.
• A Day in the Limelight: Chapter 117 delves into his Backstory.
• Face of a Thug: Even more than Blue Keeper. He wears his hair long and wild, has spiky studs adorning his ears and makeup that wouldn't look out of place at a rock concert. He gets into trouble with the local populace for this. It's no wonder why his Keeper mask fully covers his head.
• Friendly Enemy: Despite being fully aware of D being an invader, he never exposed him to the rest of Green Battalion or his fellow Keepers. Even when D tried to assassinate him in the middle of the night he let D go claiming it they were even after D saved him from getting arrested and looked forward to seeing him on their next mission. He made it abundantly clear, however, that he spared him because D's intent to kill was seriously lacking and implied he'd have killed D had it not been.
• I Call It "Vera": Green Keeper gives little nicknames to all of his tools and weapons. Unfortunately for him, he is the only one who calls them by his names, and he constantly has to correct people on their "proper" terms.
• Keeping the Enemy Close: Despite knowing D is an Invader, he doesn't out him to the rest of Green Battalion and even has him join along for missions. Even with D trying to assassinate him constantly he stays one step ahead and usually taunts him to try harder.
• The Lancer: To Red Keeper.
• Men Can't Keep House: Implied. Before he became a Keeper, he could barely take care of himself. Midorikawa, a fan of his band, would often cook and clean for him.
• Meaningful Name:With the reveal that he was around during the human-invader war and was in fact the First Green Ranger after Midorikawa's husband committed suicide . Chidori's name is this. Chidori is a thousand birds cry, specifically the japanese plover—a symbol of humanity's perseverance and family safety. Showcasing how he has preserved and maintained his sense of morality despite all the crap he's had to put up with Yellow and Red while protecting his "family" until the end.
• Mysterious Informant: As a normal civilian, Green Keeper performs work as an informant who provides his lower members of Green Battalion with useful information that he discovered.
• Only One Name: Unlike his fellow Rangers, Green Keeper only operates under one name in his civilian life. Given that he has a family, it's likely that he's just operating under a codename.
• The Plan: While confronting D over the stolen Divine Tool in chapter 5, Green Keeper suggests to Red Keeper a Plot Twist to let D live by taking him prisoner rather than just outright killing the Footsoldier in order for the latter to truly understand just how weak the Footsoldiers truly are. However, D rejects it, after which Red Keeper instantly orders his death.
• "The Reason You Suck" Speech: Gives one to D after revealing he's known D's an invader for quite some time, saying he's acting out of his Invader nature after witnessing him give a Red Battalion Ranger the option to run away.
• The Reveal: In the battle against Magatia during the Dreamy School Life arc, Chidori reveals himself to be Green Keeper in front of D.
• Scary Teeth: His Dragon Keeper suit comes with shark-like teeth.
• Seven Deadly Sins: His seven Information Broker's Tools each take a name from the Sins:
  • Sloth Brain is a tablet with access to archived news from anywhere in the world.
  • Greed Eye is a reptile-shaped spy camera.
  • Envy Medicine is, quite simply, a gun.
  • Gluttony Way is a grappling hook.
  • The timeskip introduces a replacement "Tool" in his brand new retro car, which he nicknames Lust Road.
  • Finally, Wrath Hammer is what he nicknames his Divine Tool.
• Secret-Keeper: Fully aware that D is an invader in disguise but doesn't act on it as he doesn't view him as a threat and is curious what D's end game is.
  • Also for Yumeko after her and D's failed assassination attempt on Green. While no dialogue was exchanged upon Green catching up to her, they seem to be on amicable terms as her next appearance following the reveal is her and green playing Othello at Green Battalion HQ.
• Secret Secret-Keeper: In chapter 56, Chidori mentioned a necessity for Green Battalion to blend in with the other students to further investigate Magatia's illusory world, with a special emphasis towards D as he mentioned the Hibiki Sakurama he knows is an honor student. While D had his suspicions at the time, it would later be confirmed in chapter 77 that during the conversation Chidori bugged D and spied on him over the course of the arc with one of his observer tools. The only reason he didn't expose D during the arc or even during the post-mission celebration was because he was curious as to why an Invader was infiltrating the Rangers.
• Signature Laugh: He tends to give off a "Gahahaha!" laugh whenever he is excited. Oddly, he only does it while in costume; while he's shown being amused in his civvies, he hardly laughs.
• Uniformity Exception: His day-to-day Ranger attire consists of a white hoodie and black skinny jeans, compared to the color-coded jumpsuit all the other Rangers and fellow Keepers wear. Justified as the bulk of his work is spent undercover and keeps his identity a secret.
• Walking Spoiler: Knowing that he's Chidori gives away his Dragon Keeper reveal during the Dreamy School Life arc.

Pink Keeper / Sesera Sakurama

Voiced by: M·A·O

"You don't think that's dull?"

The First Class Dragon Keeper of the Pink Battalion, and the only woman of the five Dragon Keepers. Sesera acts as a mediator between the group when they have a conflict with each others' antics, much to her dismay. Outside her ranger suit, Sesera's actual self is a paraplegic and die-hard brocon towards her younger brother, Hibiki Sakurama.

---

• Alliterative Name: Sesera Sakurama.
• All-Loving Hero: Subverted. As part of her image as The Heart of the team, she plays the part for the camera but is indifferent at best to her fellow rangers. Even with a fellow ranger dying in front of her she couldn't care less despite being the leader of the "support" battalion of the Rangers. The only exception to this is her younger brother Hibiki, whom she loves to an obsessive degree.
• Backstory: Chapter 11 delves into her backstory through a story that Hibiki tells to D. The explanation under Hibiki's Dark and Troubled Past trope goes into more detail regarding it.
• Big Brother Worship: Inverted. Sesera is a die-hard brocon, gushing over her younger brother in secret and having several body pillows and displays of him in her room. She does her absolute best to hide this in public.
• Big Sister Instinct: She's always looking out for her younger brother, Hibiki. Given that she knows how much of a pacifist he is, she doesn't feel that Hibiki's suited to be a ranger that has to fight against Invaders, and tries to get him to quit in chapter 15, not knowing that she's speaking to D disguised as "Hibiki".
• Career-Ending Injury: She was an aspiring athlete in her youth; however when she protected her younger brother Hibiki from the alien "God" that killed her parents, rubble from its blast fell onto her legs, permanently crippling her. Despite this, she joined the Rangers afterwards and was still able to climb the ranks till eventually becoming the current Pink Keeper.
• Casting Gag: M·A·O previously voiced another pink ranger, Raptor 283/Washi Pink, in Uchu Sentai Kyuranger and also portrayed Luka Millfy/Gokai Yellow in Kaizoku Sentai Gokaiger.
• Colorful Theme Naming: "Sesera Sakurama". "Sakura" or "cherry blossom" is commonly associated with the color pink.
• Curb-Stomp Battle: As part of her Establishing Character Moment, she disposes of a group of human thugs that were bothering a woman at the park.
• Cute Clumsy Girl: Has shades of being a klutz. In chapter 15, she struggles so bad at simply peeling an apple for her brother that the knife goes flying.
• Dark Action Girl: Her outer-self comes off as this, such as looking quite threatening when she's trying to convince her brother, not knowing that it's D disguised, to quit being a ranger, and she's quite capable of beating her enemies up. Meanwhile on the inside, Sesera's absolutely obsessed with Hibiki.
• Dark and Troubled Past: Pretty much experienced the same horrible past as Hibiki given that they're family (read his section of this trope). The main difference being that she used to be quite the athletic girl, but ended up losing said trait due to becoming a paraplegic.
• Dark Horse Sibling: She is Hibiki's older sister who, despite becoming crippled protecting him, still managed to rise up through the ranks of the Rangers and eventually became the current Pink Keeper.
• Disability-Negating Superpower: She's actually wheelchair-bound outside of her Dragon Keeper work, with Nadeshiko serving as her attendant. When she puts her suit on, she can stand perfectly fine.
• Establishing Character Moment: The tail end of chapter 16 provides this where she shows off how strong she is as Pink Keeper by instantly disposing of a group of thugs, then starts really gushing over Hibiki afterwards, thus showing that underneath her powerful cold exterior, Sesera's a die-hard brocon.
• Foreshadowing: In chapter 7, Yumeko calls her out for not actually wanting the former to attend the next ranger meeting as Pink Ranger just wants Yumeko's partner to attend, thus hinting at what Pink Keeper's die-hard brocon relationship towards Hibiki, the said partner, turns out to be.
• Get A Hold Of Yourself Man: During the chapter 11 Backstory, she's seen giving Hibiki a slap to the face due to Hibiki not listening to her. She did it trying to keep Hibiki from seeing their mother and father taking part in the cult that's worshipping Peltrola, their supposed "God".
• Girly Girl: Invoked, and it's heavily implied she resents being in that role. The work she gets is more fashion and beauty-based rather than anything involving the cause, which she specifically requests to never do again. Lampshaded in Chapter 16, where some local punks mock her by saying that she's only there to be the eye candy of the current Keepers.
• Healing Factor: While all of Pink Battalion has a healing factor for minor wounds, Sesera has perhaps the strongest as she was able to shrug off getting decapitated by Hwalipon. Hwalipon even declares its stronger than the healing factor of Invaders, though speculates it may have a grace period as to when it activates.
• Heroic Sacrifice: While she was initially skeptical of him first given his heavily disfigured appearance, Sesera realized he was the real Hibiki moments before Hwalipon made a surprise attack on the both of them. While Sesera was badly wounded, Hibiki was decapitated by the attack. Upon seeing his eyes and confirming that he's the real deal, she granted him her power of regeneration to revert the decapitation thereby unable to heal her own wounds. She barely managed to survive though remains comatose over a year and a half afterwards.
• Huge Guy, Tiny Girl: She's the tiny girl to Masurao's big guy whenever they're seen together as members of Pink Battalion.
• Luminescent Blush: After beating up a group of thugs at the end of chapter 16, she's so proud of Hibiki standing up to her when she tried to get him to quit being a ranger that it causes her to happily blush in excitement. This is also the moment that makes her obsession towards her brother quite clear. Granted, she didn't know that it was a disguised D at the time but the point still stands that she got excited at the thought of seeing Hibiki grow up.
• No-Sell: After getting decapitated by Hwalipon, Sesera jokes her head is still good as it was on the ground for less than 3 seconds after reattaching it.
• Passionate Sports Girl: She seemed to be a really good track runner before becoming a paraplegic. Even her battle-style as Pink Keeper has her getting in a track start position before she starts running at her enemies.
• The Smurfette Principle: Played with. While she is the sole female member of the main Ranger lineup, there are multiple other girls trying to climb the ranks throughout the organization, with some even reaching high-ranking second-in-command roles. According to Hisui, however, the position of Pink Keeper seems to be exclusive to women.
• Strong Family Resemblance: She has a uniquely designed set of eyes, which she shares with her brother, Hibiki.
• Walking Spoiler: It's a bit of a spoiler knowing that Hibiki and Sesera are brother and sister, and that the sister went on to become the Pink Dragon Keeper. However, these reveals happen so early in the story that they might as well not be spoilers.
• Women Are Wiser: Unlike her male colleagues, she's the least eccentric and the least likely to pick a fight and act out, making her the mediator of their team. She is later revealed to be Not So Above It All, with a strange obsession with her little brother and a bit of a sadistic streak.
• Yandere: She shows shades of this towards her younger brother, Hibiki. So much so that she obsesses over him during her alone time.

Ryujin - the "Dragon God"

"These people are your allies. What are you doing?"

The "mascot" of the Dragon Keepers. A very small sentient dragon-like creature with a relatively round form, making it look like a plushie. Has the ability to float.

---

• Early-Bird Cameo: Can be seen briefly in chapter 4 stationed in a Ranger Association hallway, and noticing the oddity of "Sosei Akabane" (D in disguise) walking around while a Dragon Keeper show match against the Footsoldiers is going on.
• Flight: Given that Ryujin appears to be a little dragon, it's capable of flying.
• Foreshadowing: The reason Red Keeper suddenly appears to try to stop D from stealing the former's Divine Tool is because Ryujin noticed D walking around as "Sosei Akabane" beforehand.
• Mascot: Serves as the Team Pet of the Dragon Keepers.

Former Dragon Keepers

Red Keeper / Soushi Akabane (Spoilers)

The previous Red Keeper when the Ranger-Kaijin war was still a TV program. He was arrested for his involvement in a homicide.

See his page for more info.

---

• Ambiguously Related: Has the same last name as Sosei. Considering they both have a knack for murder and playing the part of the Red Keeper, Soushi could very well be his father. Subverted, considering the reveal that he is Sosei; Soushi is just the name Sosei used during his acting career, as Yellow talks to him using the name in the Final Battle against Death Messiah.

Blue Keeper / Rikuto Aoshima

The previous generation's Blue Keeper and father to Shougo.

---

• Like Father, Unlike Son: Rikuto had a strong sense of justice while Shougo was a delinquent that frequently got in trouble with the law.
• Posthumous Character: He's known mainly through his role in the life of his son and successor as Blue Keeper Shougo.
• Small Role, Big Impact: The father to Shougo and catalyst for him taking up the mantle of Blue Keeper after his death, the owner of the orphanage that housed Sesera, Hibiki, and Shun, and implied to be a mentor figure of sorts to Sosei as he would choose Rikuto's son over his second in command Keisuke to succeed Rikuto after his death.
• The Character Died with Him: With the reveal that the first generation rangers were the actors of the tv show(barring Green), Rikuto's death was this. It's implied that his sense of justice comes from the reveal that his coworkers and friends slowly became monsters over time, with him not chatising Shougo for his role in crime because he knows what genuinely bad people are like and that his son wasn't one of them.

Blue Keeper / Shougo Aoshima

Voiced by: Go Inoue

"..."

The First Class Dragon Keeper of the Blue Battalion. With scars all across his face, he always remains silent during all his public appearances. In actuality, he's not mute, but due to his true self being a huge Sir Swears-a-Lot that gets angry rather easily, he was ordered to play the silent role amongst the Keepers. He's the carrier of the Spear Divine Tool.

---

• Affectionate Nickname: Komachi calls him "Big Blue".
• All Your Powers Combined: His real special ability is to use the powers of all of the Rangers under his command. This includes Komachi's shield, Hekiru's liquid attacks, and many others.
• Anti-Hero / Anti-Villain: Depends from which perspective you see him. He was a former criminal and even as a ranger he's still a rough man. However he also cares about his friends and genuinely fights to protect the innocents. As he puts it, he's a man who's half-assed at either good or evil.
• Arc Villain: Along with Peltrola, the Blue Keeper serves as one of the main villains of the Bailong Exams arc that D goes up against. It's also where Blue Keeper meets his end.
• Beneath the Mask: On the outside, he comes off as the stoic calm and silent type. In actuality, he's got severe anger issues to the point of yelling and swearing a lot at whatever's currently pissing him off. It's so bad that he's been ordered to act as the calm one whenever he's out in public.
• Berserk Button: Not taking the Dragon Keepers seriously is a really easy way to piss him off.
• Blue Is Calm: Played with. For public appearances he maintains a calm and quiet demeanor but it's only because he's extremely foul-mouthed and rude when actually talking.
• Blue Is Heroic: Played straight. Blue may be rough around the edges and loathes being a Ranger, but he nonetheless stepped up when Peltrola attacked, avenging his fallen comrades and nearly killing the Executive.
• Boxed Crook: Akabane threatens him with this upon their second meeting. Aoshima could very well go to jail with the rest of his crew for being accused of an unrelated murder, or he could stand in as the next Blue Keeper to replace the recently killed Rikuto Aoshima.
• Character Death: Peltrola shoots him through the neck and D stabs him during their battle in Chapter 50 with his death being confirmed in the following chapter.
• Colorful Theme Naming: "Shougo Aoshima". "Ao" is "blue" in Japanese.
• Death by Flashback: A mix of his and Komachi's flashbacks recounting Blue becoming a Keeper and their relationship. A few chapters later, Blue would be slain fighting D and Peltrola.
• Don't Tell Mama: While he was stealing millions of yen for his criminal group, the young Aoshima always took his share of the pay and put it towards his father Rikuto's orphanage. Rikuto himself has an inkling that the money's covered in blood, but he'll take whatever he can get as long as the orphanage can keep running.
• Establishing Character Moment: For the first 5 chapters, it was believed that Blue Keeper was the calm and silent one of the Dragon Keepers. Chapter 6 on the other hand shows what he's actually like, being a raging Sir Swears-a-Lot that gets pissed off quite easily, such as yelling out and raging at Yumeko just for being late to a meeting. It's so bad that Blue Keeper's been ordered to act the complete opposite while out in public.
• Former Teen Rebel: The story shows, at least, that Shougo was a petty thief at eighteen years old. He would have continued living that life if his father didn't die in the line of duty and if Akabane didn't force him to be the replacement Blue Keeper.
• Frame-Up: Aoshima and his thief acquaintances were all handed alibis by their informant, so that they wouldn't be taken in for a recent robbery. This ends up backfiring on them when the informant turns out to be a Duster, and their alibis have them at the scene of a completely different crime which resulted in the murder of a civilian.
• Friend to All Children: Despite his vulgar and flippant attitude, children love him, or at least the ones at his father's orphanage do.
• Gut Feeling: In chapter 7, Blue Keeper informs Hekiru of the oddity that even though the former controlled his strength with his Divine Tool to not kill Footsoldier D atop the Red Garrison as it would have been just a stab wound and left the building undamaged, what instead happened was said footsoldier exploding (Foodsoldier D used Yumeko's dynamite to make it look like Blue Keeper killed him in order to get away). As a result, Blue Keeper's left feeling that something's off. Their worst case scenario is that Footsoldier D escaped and made off with Red's Divine Tool. Thus, he orders Hekiru to investigate if the footsoldier got blown away by the wind when said footsoldier dusted back to the Sky Fortress while Blue Keeper investigates the fortress himself. The former ends up being the case as Hekiru discovers the stabbed Footsoldier D in the nearby forest.
• Jerk with a Heart of Gold: Leans heavy towards the Jerk. While Blue is a handful to everyone he knows, he still has a legitimate sense of justice and won't hesitate to deal with opponents who hurt his subordinates. He'll especially get fired up if Komachi is hurt. However, D suggests that while his heart might be in the right place, his protectiveness towards his friends and allies is probably just his excuse to go all out on people he perceives as the enemy.
• Jousting Lance: His divine tool, making him a literal lancer.
• Making a Splash: All of his power-based attacks use water/the ocean as a theme. He can summon bubble bombs with various sea creatures, shoot out a stream of concentrated water, and much, much more. Also combined with Water Is Blue.
• Pay Evil unto Evil: He is not nice to his opponents. If someone he perceives as a threat is knocking the living daylights out of something or makes their disdain known, he'll pay them in kind with extra. He once throttled a whole gang for abusing a kitten, and tries to brutalize XX once he discovers she's a Footsoldier.
• The Quiet One: Whenever he's in public.
• Reformed Criminal: By the time we see him in the present, he's actually fairly devoted to being the Blue Rangers' leader, and he's well past his history of crime. He hasn't fully reformed however, since his violent streak is still there.
• Refusal of the Call: Despite being the son of the previous Blue Keeper, he was a delinquent in his youth and wanted nothing to do with the Rangers. It took the death of his father and persistence of Abakane to get him to take up the mantle.
• Scars Are Forever: You can clearly tell that he has some pretty gruesome facial scars. Scars that he picked up before becoming the Blue Keeper.
• Sir Swears-a-Lot: The reason he maintains a silent persona while performing as Blue Keeper is because he's extremely loud and vulgar. His fellow Keepers thought this would not be a good reflection of a "good guy" so they make him remain silent at almost all times. His attache, Komachi, even mentions that if he were to speak during the battle, the children would be more scared of him than the Kaijins.
• Worf Had the Flu: Make no mistake, he's the Blue Keeper for a reason and is fully capable of beating an army of Peltrola's clones near-singlehandedly. But he's not invincible and said fight runs him ragged, allowing even a lowly Mook like D to fight him on equal footing afterwards and ultimately getting killed by a sneak attack from Peltrola.

Pink Keeper / Saika Momoe

The first generation's Pink Keeper.

---

• Never Suicide: Implied. Momoe was found dead in her own apartment, having apparently killed herself shortly after giving her testimony on the early years of the war to Ukyo. Considering Rangers had been tailing her for a long time and Akabane had already noticed Ukyo, it's likely they put Momoe down.
• Posthumous Character: Momoe has been dead for a few years by the time the story starts, killed when Ukyo and Sazan were already adults.
