- Bratty Half-Pint: He's very loud and often immature.
- Heroes Prefer Swords: He's given a laser sword in the second episode, and uses it as his main weapon for the rest of the series.
- Heroic BSoD: When Nyanma's Jyarei Elite come into play, all four are revealed to be cats like her. The Eto Rangers' first encounter against one left Bakumaru frozen due to his instinctual fear of cats. Seeing two at once, later on, savagely enforces the BSOD to the point where he is unable to do anything. It took a trial in the Illusion Room in Princess Aura's castle, and help from feline friend Gaou, to overcome this fear for the rest of the series.
- Freudian Excuse: His fear of cats stem from constant bullying from a cat named Chocolat in the past.
- Jerk with a Heart of Gold: Despite being kind of hot-headed and in your face, he's really a compassionate guy underneath. And in his defense most of his worst moments are more him being Innocently Insensitive than anything else.
- Laser Blade: Primary weapon after the end of the second episode, as it was unaffected by the Novel World's restoration.
- The Leader: Placed first in a race to decide the twelve Eto Rangers
- Nice Mice: Although "nice" may be stretching it a bit, he does have a good heart.
- Official Couple: With Cream.
- Rousing Speech: Bakumaru's pretty good at loudly reminding his team about their mission when they're experiencing despair. At one point, he had a tear-jerker story called "Shanghai Cabbage" for this purpose, but after a stressful mission, he forgotten how it went, much to Souffle's frustration.
- Took a Level in Badass: Bakumaru later gets his own Finishing Move and manages to overcome his fear of cats.
- Took a Level in Jerkass: He acts like a real asshole in the Puss In Boots episode where he throws a tantrum over going to a novel world with a cat in it. He does, however, have a good Freudian Excuse for acting that way.
- Why Did It Have to Be Snakes?: As a mouse, he has an instinctive fear of virtually all felines, thanks to Chocolat's frequent bullying before the series began. Only Gaou, a tiger, is an exception to this. He overcomes this fear midway through the series from a trial.
- Big Guy Fatality Syndrome: Hols is one of the first two Etorangers to be killed.
- Bull Seeing Red: Hols' main contribution to the team is his ability to change into a larger, stronger, four-legged bull if he sees red.
- Butt-Monkey: One of the more frequent receivers of slapstick and is perhaps the least respected member of the team
- Fat Comic Relief: Usually, he's played more for laughs than for drama and is often a source of comedy.
- Shoo Out the Clowns: As stated before, he a big source of comic relief and is one of the first of the rangers to die.
- Wholesome Crossdresser: He has crossdressed twice in the series.
- Berserk Button: Don't threaten innocent young girls in front of him. Some enemy ninjas who kidnapped Otama in episode 17 found out the hard way.
- Gentle Giant: He's large and muscular but he's easily the most gentle tiger you'll see in an anime.
- The Only One Allowed to Defeat You: During the final episodes, he attempts to finish off Nyanma, even after learning the she is his old friend Chocolat, as she (and by extension, one of her Elite) had already killed off half of his team. He is distracted by an illusion she used, long enough for her to deliver a critical blow against him.
- Panthera Awesome: A tiger to be exact.
- Transformation Trinket: His sunglasses allow him to transform into a larger, stronger, four-legged tiger.
- Deadpan Snarker
- Green-Eyed Monster: She'll sometimes get jealous when it comes to Bakumaru, and it becomes a source of conflict in episode 16.
- Ms. Fanservice: Sometimes turns into this courtesy of her disguising ability, she even becomes (fittingly) a Playboy Bunny in two episodes.
- Nice Girl: Cream is a very nice girl, serving as emotional support for the team along with Souffle.
- Official Couple: With Bakumaru.
- Righteous Rabbit
- Tomboy and Girly Girl: She and Souffle are girly girls in comparison to the more tomboyish Tart.
- Transformation Trinket: She owns a magical staff that lets her magically change into different disguises.
- Big Guy Fatality Syndrome: Drago is one of the first two Eto Rangers to be killed.
- Only Sane Man: Relatively speaking at least.
- Our Dragons Are Different: An interesting combination of both Western and Eastern dragons, though is mostly based off of the latter.
- Pragmatic Hero: In one episode, he suggested not returning to Bakumaru's group right away, as he was sure that Bakumaru would understand and Drago's group needed to prioritize defending Princess Aura, who was under attack that episode.
- Transformation Trinket: His "Adult Drop" can transform him into a much bigger dragon.
- Adorkable: He's a nerdy goofball snake with glasses and a habit of saying his own name after every sentence so of course he's this.
- Floating Limbs: Being a snake, he has no arms, but gloves that can work as hands.
- Gadgeteer Genius
- Smug Snake: A rare benevolent version. He can be prone to bragging.
- Battle Boomerang: In combat, Pakaracchi can throw horseshoes like boomerangs.
- Big Fun: More muscle than fat but he still qualifies.
- Boisterous Bruiser: He's almost always in a cheerful mood and is easily one of the more muscular rangers, often going on about youth a lot.
- Love Freak: He's very fond of talking about how great youth is. Most of his dialogue is guaranteed to include the word "youth" in it.
- Nice Guy: Very jovial and friendly to just about everyone. If you mess with his friends, however...
- Badass Adorable: Enforces this in The Boy Who Cried Wolf episode.
- Beware the Nice Ones: There will be times when someone as sweet as Souffle get mad, but those are far and few in between.
- Hidden Depths: Souffle is pretty good with technology, as shown by her "radar compact", and she develops good leadership skills in episode 24.
- Nice Girl: Easily one of the purest and kindest characters in the series.
- Reluctant Fanservice Girl: A victim of this for just a few seconds in episode 3.
- Rose-Haired Sweetie
- Supreme Chef: In episode 16, Bakumaru mentions that Souffle's cakes are so good that he wouldn't miss them for the world.
- Sweet Sheep: And how.
- The Load: Lampshaded by herself in episode 24, as she feels she does not contribute enough to the team, she spends the rest of the episode in an attempt to defy this during a mission that included her, with surprisingly good results.
- Thinks Like a Romance Novel: It comes in handy at times.
- Tomboy and Girly Girl: She and Cream are girly girls in comparison to the more tomboyish Tart.
- Everyone Has Standards: Even Monk has a line drawn when it comes to pranks. He once used Princess Aura's voice, one of great authority, for a water bucket prank. However, when he was accused by Pochiro of using this same method to deceive Chocolat into disqualification, during the race to choose the next Eto Rangers, he angrily says that not even he would stoop that low.
- Everything's Better with Monkeys
- Expy: In terms of personality and his clothing, he bares more than a passing resemblance to Son Wukong.
- Jerk with a Heart of Gold: He plays pranks a lot and can tick people off, but he isn't deliberately mean.
- The Prankster
- Boobs of Steel: The strongest fighter out of the females and in both of her forms she is the bustiest. She is a chicken after all.
- Berserk Button: Insulting her big butt.
- Clucking Funny: When her first form's face appears on the second form.
- Feather Fingers: First form (Chicken/Hen).
- Miss Fanservice: Second form (Human). Tart is seen more often here after its debut.
- Ship Tease: With Pochiro, especially in the last episode.
- Team Mom: Despite being a gruff tomboy, Tart can very quickly soften up and be remarkably loving to both her teammates and to others.
- Tomboy and Girly Girl: In comparison to girly girls Cream and Souffle, Tart is significantly more tomboyish.
- Adorkable: An interesting case. Most of the time, he's a badass comedian but there are times where he shows a cuter, much more laid back and comedic side to his personality. Just look at him while he's dressed in his baker, pilgrim and punk rocker outfits from the Hansel And Gretel, Bluebird Of Happiness and Bremen Town Musicians episodes, respectively. He's extremely adorable.
- Badass Adorable: A kooky comedian guy who will wreck you will his Bone Nyoibo.
- Berserk Button: He absolutely hates being pranked, being the very first ranger to physically lash out at Monk in one episode where all the rangers were pranked.
- Cry Cute: Whenever he sheds tears, expect Pochiro to cross into Moe territory.
- Deadpan Snarker: His sarcasm is just as sharp as his bushido. It's easpecially notable around Bakumaru and Monk.
- Everything's Better with Samurai
- Go Out with a Smile
- Heroic Dog: Anthropomorphic variant
- Jerk with a Heart of Gold: He's a bit gruff and sarcastic at first but he's also one of the most loyal Eto Rangers and even sacrifices his life to protect a fellow ranger
- Samurai Ponytail
- Shock and Awe: His Bone Nyoibo has a built in taser.
- Sophisticated as Hell: Often uses old Japanese samurai dialect and something mixes it in sentences when he insults Monk.
- Taking the Bullet: Willing to take a hit, fatal or not, to protect his friends. This includes protecting Monk with his very life against Nyanma during the final episodes.
- The Baby of the Bunch: Urii is the youngest member of the Etorangers.
- Berserker Tears: Urii's main contribution to the team is his ability to fire a huge laser out of the crystal on his chest when he cries.
- Infant Immortality: He's one of only three Etorangers who survives Nyanma's onslaught near the end of the series.
- Big Good: Aura gave the Etorangers their task of restoring the Novel Worlds to normal, and all of the Etorangers greatly look up to her.
- Cast from Hit Points: Aura has used her magic to drive away the powerful Nyanma twice in the series. She has also assisted the Eto Rangers, in more ways than one. Unfortunately said magic leads her to faint and be confined in bed.
- Nice Girl: She's a kind person, and when Nyanma personally attacks her at one point, Aura is regretful of Nyanma going down the wrong path, as opposed to being afraid of Nyanma personally.
- Princesses Rule: Aura is known as "Princess Aura" and not as "Queen Aura", despite being the sole ruler of the country of Mugen. However, this may be justified as Aura herself answers to the Great God Goal.
- Beware the Silly Ones: As is shown in almost every episode, Kirinda may be a incredibly goofy but he is a force to be reckoned with when he is ready to purify a world.
- Bunny-Ears Lawyer: It's thanks to him the rangers can get from world to world and is the main reason they can purify the worlds... He is also a very sarcastic and eccentric character who frequently cracks jokes.
- Finishing Move: Is always needed to be summoned to finish off a Jyarei monster. Started off as a wave, then upgraded to a lightning attack.
- Living Ship: Was revealed to been reincarnated from a previous life. Was revived and turned back to normal in the final episode.
- Mid-Season Upgrade: He was nearly destroyed by two of Nyanma's Jyarei Elite. The team found a special item that not only restored him, but gave him a major power boost needed to destroy said Elite.
- Reincarnation: Kirinda was later revealed to be Mugen Times reporter Lydia, reborn as the Eto Rangers' vessel by Aura, after being killed by Nyanma.
- Troll: Many of his jokes are at the expense of the rangers.
- Big Bad: She commands the Jyarei Monsters to corrupt the Novel Worlds and destroy the Novel Pole. Subverted when it's later revealed that Nynama was being manipulated by Bagi.
- Boobs of Steel: One of the strongest characters in the show and has a very large bust she barely covers. Fittingly, when she is turned back to her normal form her breasts shrink tremendously.
- The Bully: As Chocolat, she chased Bakumaru around a lot — which give Bakumaru his fears of cats.
- The Dragon: Nyanma is this to Bagi, though at first she seems like the Big Bad for most of the series.
- Freudian Excuse: As Chocolat, she mistakenly thought Princess Aura had appeared to her in a vision and told her to start the "Etoranger qualification race" early, causing her to be disqualified by unintentionally cheating. Chocolat thought that Aura had deliberately set her up to be humiliated, so she accepted a deal with Bagi that turned her into Nyanma for the sake of getting her revenge on Aura. Ironically, it was Bagi herself who was behind the fake vision that caused the misunderstanding to begin with.
- The Reveal: The leader of the Jyarei Monsters that has been menacing the Novel Worlds is none other than Gaoh's old friend Chocolat, who wanted to be an Etoranger but was disqualified from the qualification race, mistakenly believing that Princess Aura was responsible.
- Big Bad: Though you don't know that until near the end of the series, as Nyanma seems the biggest threat for most of it.
- Laser-Guided Karma: In the end, she is defeated when Nyanma decides to turn against her and help the Eto Rangers, after Nyanma learned that Bagi was just using her and was responsible for her disqualification from Princess Aura's race.
