Main Characters

The male main character.
An adventurer who somehow got turned into an infant Behemoth.
  • Affectionate Gesture to the Head: On both ends. Aria and Vulcan frequently pet him on the head, and when he can, he rubs his body against or licks Aria in the face, which she greatly enjoys.
  • Animal Companion: How the world at large sees him. As long as he gets to stay close to Aria, this serves him just fine.
  • Bathtub Bonding: Invoked. Aria orders him to bathe with her.
  • Bedmate Reveal: The first time he wakes up in Aria's home, he's in her bed and she's cuddling him in her cleavage.
  • Breath Weapon: Elemental Howling.
  • Cannibalism Super Power: Like all other monsters to date, he gains new abilities by eating other monsters, which he discovers when he eats a slime.
  • Can't Have Sex, Ever: At least until the events of Chapter 7. Even then, his "Behemoth" body's too young...
  • Combo Platter Powers: Just from his initial "Elemental Howl" skill
  • Cover Blowing Super Power: Any of his abilities would reveal him as a "monster" and could get him killed. Fortunately there's another "cat" species that has magical powers.
  • Covert Pervert: By virtue of being unable to speak, his perversions go unsaid, but he loves to ogle his "master" Aria when she changes and is fixated on her chest.
  • Crazy Jealous Guy: He is very, very protective and possessive of Aria. Get too close to her, and he will lash out and attack you, damn the consequences... unless Aria restrains him.
  • Hammerspace: Invoked. He gains a "Harvesting" skill that allows him to store things in an alternate dimension.
  • Hypocritical Heartwarming: He hates people eyeing Aria with perverted intentions, but when he does it... It's okay. To his credit Aria wants him to look at her with perverted intentions.
  • I Owe You My Life: To Aria, twice in a row. She saved his life when he was mortally wounded, and spared him after he revealed he was a monster.
  • Killer Rabbit: He looks and acts like a house-cat most of the time, but he's a veteran knight that was reincarnated into a Behemoth.
  • Lady and Knight: Which is lampshaded frequently, especially by himself. He's the knight to Aria's lady.
  • Love at First Sight: The first time he sees Aria's face, he mistakes her for an angel from Heaven. He's been smitten with her ever since.
  • Marshmallow Hell: Constantly subjected to this. Both Aria and Vulcan love to carry him around on their bosom, and he loves being carried that way.
  • My Master, Right or Wrong: He views Aria's word as law, no ifs, ands, or buts.
  • No Guy Wants to Be Chased: Tama does not like it when any woman, not even Aria, gets too sexually aggressive.
  • Not Afraid to Die: Both when he's mortally wounded in chapter 1, and when he rescues Aria in chapter 3, he's completely resigned to having her kill him as a "monster." He's shocked when she literally picks him up and cares for him both times.
  • No Name Given: His name when he was a human knight is never revealed.
  • Property of Love: He is very content to be Aria's official "pet" and acknowledges her as "Master."
  • Subordinate Excuse: How he rationalizes happily joining Aria in the bath, or ogling her in her bedroom as she changes. He has to be nearby to guard her if something happens, after all. In his defense, this is precisely the way Aria wants it.
  • Super Mode: Behemoth, Evolution level 2...
  • Taking the Bullet: He shields Aria from sword blows during their duel with Kassman repeatedly.
  • Undying Loyalty: He is completely devoted Aria, for life.
  • The Voiceless: He can not speak, at all. The only sound coming out of his mouth is "NYAN" or some other meowing sound.
  • Your Size May Vary: Illustrations of him can't decide how big he's supposed to be. In some instances, he fits nicely in Aria's palm. In others, he's depicted as a full-grown house-cat.

Yes, he is.
An adventurer who picked up Tama and adopted him.
  • Achievements in Ignorance: She's still not aware of it, but she has won the unwavering loyalty of a "Behemoth," the most powerful and vicious of monsters on the planet... because she mistook it for a lost and hurt alley-cat, brought it home and treated it very, very kindly.
  • Androcles' Lion: She picks up and tends the wounds of a mortally wounded "cat." This creature follows her into the dungeon and saves her from a Goblin fireball.
  • Bare Your Midriff: Her adventuring outfit exposes her lower abdomen. She justifies it as a necessity for her fighting style.
  • Bestiality Is Depraved: Played with. While she is rightly disgusted by the idea of dungeon monsters wanting to lewd her, the fact that she's sexually attracted to Tama, whom she can pass off as an Elemental Cat, a species known to "attack" their owners during mating season, is so adorable, the general population is actually envious.
  • Beware the Nice Ones: Very sweet and caring, but piss her off, and there might not be enough left of you to bury.
  • Cerebus Retcon: Combined with Adaptation Expansion and Troubled Backstory Flashback. The manga goes into greater depth as to why she's so attracted to Tama and sour on the male gender. As a child, she suffered a near-rape experience and was rescued by the elven saint's Elemental Cat. She flashbacks to this memory while she's recovering from Beryl's poison.
  • Clingy Jealous Girl: Defied. She puts Tama on the breasts of her female friend, Vulcan, repeatedly, and finds it adorable when he snuggles in. What's more, as much as she likes snuggling Tama in her bosom, she likes other women snuggle him in their bosom even more.
  • Does Not Like Men: She is sour on the entire male gender, with the exception of Tama.
  • Doomed Hometown: Up to Eleven. She comes from a Doomed Home Country. She's the Lone Survivor of her home nation, and then only because she was rescued from a "Demon" army by a female elf known as "Legendary Fencer." (Or Sword Saint)
  • Fantastic Arousal: While she's normally quite horny where Tama's concerned, when he simply licks her ears (like cats are wont to do), she goes full-tilt sex-crazy.
  • Fragile Speedster: Her fighting style involves accelerating to high speeds and then hitting hard, but her movements are very easy to read, and when countered, she goes down hard.
  • Friend to All Children: In chapter 9, she comes across a couple of thugs beating up on a pan-handling orphan. Not only does she go out of her way to rescue the child, but she gives the child a healing potion and then pays for the child to attend a convent, where the child can grow up safe and happy... To her chagrin because she wanted to raise the child herself, but couldn't.
  • Gainaxing: Exploited. She uses the momentum of her massive buxom as major part of her fighting style.
  • Hair of Gold, Heart of Gold: Described as a platinum blonde, and a very sweet, sensitive woman.
  • Hero-Worshipper: She was rescued from genocide by "Legendary Fencer" and worships her to the point she wants to become just like her savior, and stand by her side.
  • Innocent Blue Eyes: Combined with Icy Blue Eyes. Tama describes her eyes as blue as ice, but she's a sweet and innocent woman.
  • Innocent Fanservice Girl: At first. The first time she changed in front of Tama, she thought he was a simple alley-cat. Once she's informed that Tama is from a species of cat that might be sexually attracted to her, she goes full-tilt Shameless Fanservice Girl to try and flaunt her assets in front of him.
  • Is That What They're Calling It Now?: "We'll do lots of Nyan, Nyan together." Even Tama is confused by it.
  • Kind Hearted Cat Lover: She put a quest on hold to rescue Tama, who she thought was just a stray cat.
  • Lust Object: To the entire male population of Maze City, and she knows it. She does not like it.
  • Pervert Revenge Mode: She tolerates people leering at her because she's an upstanding citizen, but if she's able, she will respond with violence to anyone, or anything, that tries to lewd her, with the exception of Tama, whom she explicitly wants to lewd her, and who she would lewd if she could.
  • Razor Wind: Which she learns in Chapter 7, as a direct result of a Roper monster trying to lewd her, and she went Pervert Revenge Mode.
  • Rescue Romance: Because Tama came to her defense against a goblin mage in the labyrinth, she's completely smitten with him. She is very grateful that he's devoted his body and soul to her and would love to give him her virginity, if she could.
  • Single-Target Sexuality: She is entirely Tama-sexual. Anyone or anything else who tries to hit on her is likely to be met with violence, the moment she thinks she can get away with it.
  • Victoria's Secret Compartment: To the point that she can hold a living cat in her cleavage.
  • Zettai Ryouiki: Type a. She wears a very short skirt and very high boots/stockings.

Aria's friend and favorite blacksmith
An adventurer and blacksmith. She joins Aria and the two form party.
  • Cat Girl: Being a female tiger-kin, she has several cat traits.
  • Drop the Hammer: She wields a war-hammer in battle.
  • Intrepid Merchant: When she can't purchase needed materials to make her armors and weapons, she goes dungeon crawling to get them.
  • Little Bit Beastly: As a tiger-kin, she has tiger ears and a tail.
  • Reality Ensues: In chapter 7, she forms a party with Aria and Tama because her original party was disbanded due to her primary dungeon diving partner getting pregnant and going on maternity leave.
  • Ultimate Blacksmith: She's so good as a blacksmith, that she makes fully functional armor for Tama, and imbues it with magic so he never outgrows it.
  • Verbal Tic: Being a Cat Girl, she ends her sentences with "Nyaa." She and Tama make a game of it near the end of chapter 6.


Introduced in chapter 3, he's obsessed with Aria and won't take "no" for an answer.
  • Abhorrent Admirer: He lusts after Aria, but his mannerisms, and skirt-chasing history make him utterly repulsive to her.
  • And Now You Must Marry Me: He forces Aria into a duel she's not likely to win, Tama's life on the line, to have her marry him, just because she's his latest Lust Object.
  • Anime Hair: Just look at the page image. The light novel notes that his hair is deliberately slicked back like that with some kind of gel...
  • Antimagic: Due to a family treasure, magical attacks are useless against him. Non-magic skills on the other hand...
  • Aristocrats Are Evil: He's the first born of a noble, and is highly abhorrent.
  • The Bully: He loves to throw his weight around.
  • Did Not See That Coming: He didn't realize that "Elemental Cats" can have non-magical inherent skills...
  • Disproportionate Retribution: He drew a sword in the adventurer's guild hall on Tama when Tama bit his hand and then scratched him, after he tried to grab Aria and drag her into a "party" with him. When the guild-master rebuffed him, he returned with an execution order on Tama.
  • Entitled to Have You: To Aria. He pointedly refuses to accept the fact that she's clearly not interested in him.
  • Groin Attack: On the receiving end from Aria, and he really, really had it coming. It was so vicious, he might not survive it. note 
  • Hate Sink: From his introduction, his obsession with Aria made the fanbase wish for his death. The Groin Attack he receives in chapter 6 was considered too lenient... even if it turns out that he didn't survive.
  • Punched Across the Room: Tama blasts him with Aether Howling in chapter 6, slamming him into a wall.
  • Reality Ensues: On both ends. When a pet being held near its owner's bosom senses its owner is in distress, especially if this distress is due to somebody it doesn't recognize getting too close, it will attack the intruder. There are also laws in existence where people attacked by animals can call for the offending animal to be put down, and there are people petty enough to go after people's pets when they feel slighted by the pet's owner, for little to no reason.
  • Smug Snake: His entire on-screen appearance involves harassing Aria without her being able to retaliate due to his noble status, until he forces her into a duel with him in volume 6, where he bullies Tama and Aria, trying to break her will. The moment the tables are turned, he's revealed to be a cowardly mess, and Aria makes him pay, harshly.
  • Uncertain Doom: The duel terms, as listed by Ana, the guild master were victory is determined by one party surrendering or dying. He didn't surrender, though he was taken away on a stretcher...
  • Villains Want Mercy: After bullying Aria and Tama in a "duel" for the majority of chapter 6, when Tama manages to turn the tables, slamming him into a wall, and having all four of his limbs bent in awkward angles, he begs forgiveness. Aria does not comply.

     Beryl Astaroth
Feed my monsters with your lives, humans, and be the stepping stone for my revenge!
The first Demon shown to the audience.
  • Barrier Warrior: His special ability allows him to create powerful multi-layered forcefields which he uses to separate the adventuring party, thinking this would make them easy pickings for his trolls. Too late, he realizes this line of thinking was wrong.
  • Bond Villain Stupidity: He could have escaped after his monsters were wiped out by the adventuring party, and set up shop elsewhere, completely unnoticed, since none of the adventurers had seen him, but instead chooses to go and confront them, in person. He winds up paying the price.
  • Doomed Home Town: His village was wiped out in the human/demon war, Ragnarok, and is now populated by humans.
  • Meaningful Name: Named Beryl, has green hair.
  • Revenge Myopia: Wants revenge against the humans inhabiting what was his home town, but conveniently ignores how his people not only annihilated entire countries, but began the practice of eating humans, and feeding humans, alive, to their "monster" livestock, which triggered the war in the first place, which is also a practice he and his people continue to the present day, and he still has the gall to be incensed that powerful human adventurers are sent to investigate.
  • Screw This, I'm Outta Here!: When he realizes that the adventurers sent to investigate and eliminate the one who's kidnapping humans, himself, are way stronger than his estimates accounted for, he tries to flee, but it's too little, to late for him at this point.
  • Suicidal Overconfidence: He truly believed he'd reached the point in his so-called planning where he was unstoppable. He was dead wrong.
  • Taking You with Me: He tries, by poisoning Aria with a powerful and nearly incurable poison in his death throes. Unfortunately for him, Tama knew where to find the antidote...
  • This Cannot Be!: The moment he realizes an "Elemental Cat" is among the party of adventurers sent to deal with him, and said cat tears through his monster mooks like they're made of paper mache.
  • You Gotta Have Blue Hair: Poison Green.


Real Name: Arnaldo Hwarzenegger. The guildmaster of the adventurer's guild in Maze City.
  • Bald of Awesome: Not a strand of hair anywhere on the body, but is a retired B-ranked adventurer and runs the guild with a firm hand.
  • Bunny-Ears Lawyer: Walks around in nothing but a cod-piece, but is a very skilled guild leader and former adventurer.
  • The Dreaded: To trouble-makers in the guild. Punishing troublemakers without a shred of mercy is Ana's favorite "hobby."
  • Hypocritical Humor: Is aghast at Aria's unusual tastes, yet has very unusual tastes too...
  • Parody: Of a certain California governor...
  • Reasonable Authority Figure: As the guild-master, Ana makes sure the adventurers are given quests that match their abilities, and experience, and can be trusted by all, even Aria.
  • Retired Badass: Used to be a rank B adventurer, but retired from adventuring to run the guild.
  • Spell My Name with an "S": Arnaldo Hwarzenegger or Arnald Hozinegger?
  • Transsexual: The light novel indicates that Ana is a pre-op MTF.


    In General 
  • Always Chaotic Evil: They are invariably hostile to the people of Maze city. Peaceful co-existence or communication is impossible. Tama is the only exception, and then only because he's a reincarnated human male knight.

  • Child by Rape: Invoked. They are notorious for kidnapping and capturing women, of all humanoid races, to repeatedly rape and impregnate for the rest of their lives.
  • Quantity vs. Quality: They may not be very strong monsters, but they make up for it in terms of sheer numbers.
  • Starfish Language: All they say is "Gii" with various inflections, but it's a clearly complex language of some sort.
  • Starter Villain: The first antagonists faced by any adventurer.


  • It Can Think: Listed as the first of many monsters with actual sentience.
  • A Load of Bull: As expected of Minotaur, they have heads and legs like bulls, with torsos and arms of men.
  • Screw This, I'm Outta Here!: The first species of monster that actually tries to run when finding itself on the losing end of battle. The rest just attack mindlessly.


Troll Smash!

    Earth Dragon/ Stella 
The monster that almost killed Tama in chapter 1.
Be afraid, be very afraid.
Mightiest one! Give me your child!
  • Adaptational Modesty: In the original light novel, Tama encounters her humanoid form buck naked. In the manga, she's wearing something that barely passes for a dress.
  • Amnesiac Hero: What Aria and Vulcan think of her. Only she and Tama know the truth, but they're not telling.
  • Blood Knight: As explained in her side-chapter, she lives for the thrill of hunting foes capable of putting up a good fight; the reason he sleeps on the lowest floor of the dungeon is sheer boredom. This trait carries over to her reincarnation.
  • Defeat Means Friendship: Or rather, defeat means "crazy stalker who keeps chasing Tama down and trying to have Tama impregnate her!"
  • Disk-One Final Boss: Found on the lowest level of the dungeon.
  • Disproportionate Retribution: Disturb its sleep in any way? Even from accidentally walking on it? Your life is forfeit!
  • The Dreaded: Even full-grown behemoths are wary of it.
  • Entertainingly Wrong: Due to her Might Makes Right mindset, she's terrified of Aria due to the fact that Aria treats Tama, the guy who gave her killed her via No-Holds-Barred Beatdown, like a cub, and Tama lets her.
  • Eye Scream: Tama manages to blind it in one eye, in return for it nearly disemboweling him.
  • Heel–Face Turn: After reincarnating, she becomes a powerful ally for Tama, Aria, and Vulcan, officially joining their adventurer party.
  • Hero Killer: Almost. Tama managed to escape by the skin of his teeth, and even then would have died if Aria didn't find him and tend his wounds.
  • I Just Want to Have Friends: She finds the idea of fighting side by side with Aria, Vulcan, and Tama fun, and greatly enjoys their company.
  • Lizard Folk: Her reincarnated form is officially recognized as "Dragonewt" by the residents of Maze City.
  • Mutual Kill: Subverted. This was clearly its intention when she and Tama fought the second time, and she realized escape was impossible, but Tama survived.
  • Nice Job Fixing It, Villain!: Had it not mortally wounded Tama, he and Aria would likely have never met and become a couple. What's more, fighting Tama in the first place opened a Dungeon Bypass that allowed Tama to find his way out of the dungeon.
  • Oh, Crap!: When he's facing Tama in a "rematch" and Tama reveals his Super Mode.
  • Reincarnation: After the Earth Dragon is defeated, Tama comes across a very attractive, very naked, woman screaming "I've found you, powerful one! Give me your children!" and continuously pursues him, to his chagrin. A few chapters later, she openly admits to Tama that she is, in fact, the Earth Dragon he killed to get the antidote for Aria.
  • Stripperific: Justified. Her "human" form can't wear too much in terms of clothes because she undergoes a partial draconic transformation when going into battle, and those clothes would shred like paper in the process.
  • Telepathy: Can communicate directly to Tama's mind.
  • Trauma Button: Due to the way Tamma defeated her, she has a lasting trauma regarding monsters with abilities she does not understand. She tends to be paralyzed in fear when this happened.
  • Villain Respect: Goes from calling Tama "weak one" to "little one" to "powerful one" when Tama returns and starts giving her a No-Holds-Barred Beatdown.


How well does it match the trope?
