About

A world where beastmen exist as a matter of course. Because beastmen look like human babies, they are sold in beastman shops and sometimes kept as human pets.

However, many individuals cause significant trouble for humans. Since beastmen have no human rights, no matter what is done to them, it is never considered a crime.

┈┈┈┈┈┈┈┈┈┈

There are many mysteries surrounding the ecology of beastmen. In the basement of a certain research institute, five cheeky beastmen who caused trouble for people have been detained, and experiments using them as test subjects are about to begin. At this point, only height and weight measurements have been taken. Now, what shall we investigate next?

Characters

Kaka

Features

  • A crow beastman with pitch-black crow wings growing from his back. Human hands but crow feet.
  • He troubled people by rummaging through trash repeatedly. One day, a human saw Kaka rummaging through trash and reported him to a beastman capture agency; after capture, he was sent to the lab.  

Personality

  • Cheeky and prideful. Thinks he is the most important.  

Likes: Shiny things, making others obey him   Dislikes: Being ordered around, painful or painful things, having his wings touched

  Other

  • First person: Kaka
  • Guest: Human
Chuchu

Features

  • A mouse beastman with mouse ears and a tail. Gray-colored.
  • He broke into people's homes to scavenge food and chewed on buildings and power lines, but was caught by the agency and sent to the lab.  

Personality

  • Cheeky and prideful. Steals others' food. Lashes out at objects immediately. Speaks with a lisp. Habitual saying: "Chu didn't do anything wrong-chu!!!"  

Likes: Eating stolen food, causing trouble for people, gnawing on anything and everything to leave tooth marks (he considers this proof of strength, though he's grumpy that he can't leave marks on iron bars or metal)   Dislikes: Having his things stolen, being made fun of, having his ears or tail touched, pain

  Other

  • First person: Chu
  • Guest: Human
Mome

Features

  • A seagull beastman with seagull wings. Human hands but seagull feet. Wears a white seagull-themed hooded romper and always keeps the hood up.
  • He dirtied coastal tourist spots with droppings and was noisy with his cries regardless of the time, so he was captured by the agency and sent to the lab.  

Personality

  • Cheeky and prideful. If even the slightest thing displeases him, he immediately throws a tantrum, thrashing violently and screaming louder than anyone else.  

Likes: Getting his way, swimming, fishies (he thinks they are his friends)   Dislikes: Disgusting lab food, dark and narrow places, lack of freedom, being told to be quiet (he gets angry and becomes even louder), pain

  Other

  • First person: Mome
  • Guest: Human
Mogugu

Features

  • A mole beastman with mole limbs. Wears a dark brown mole-themed hooded romper and always keeps the hood up. Has straight-cut bangs.
  • With the mindset that as long as he's having fun it's fine, he dug holes without considering the trouble he caused, damaging plant roots and ruining lawns and fields. Numerous reports were filed, and he was sent to the lab after capture.  

Personality

  • Cheeky and prideful. Decides that humans are enemies and intimidates them by showing off his prized mole claws. When angry, he has bad manners, such as throwing food at humans or other beastmen.  

Likes: Digging holes, feeling superior   Dislikes: Hard places where he can't dig (= the lab), pain

  Other

  • First person: Mogu
  • Guest: Human
Pon

Features

  • A tanuki beastman with light brown tanuki ears and a tail. Limbs are the same as a human baby's.
  • He was captured and sent to the lab after breaking into people's gardens and fields to eat crops and fruit without permission.  

Personality

  • Cowardly and fearful. Highly cautious and harbors a fear of humans. He easily warms up to humans who are kind to him, but is extremely afraid of other humans and keeps his distance. If caught or unable to move, he panics and screams.  

Likes: His own fluffy tail (cherishes it like his own child), fruit (especially persimmons), beings who are kind to him   Dislikes: Pain, scary things, dark and narrow places, having his tail touched by anyone other than those he trusts. Since nerves are concentrated in the tail, he extremely dislikes it being touched and instinctively tries to protect it.

  Other

  • First person: Pon
  • Guest: Mr. Human
ぴょこ

Features

  • A rabbit beastman with light pink rabbit ears and a tail. Limbs are the same as a human baby's.
  • He was reported and caught after gnawing on the bark of trees and saplings, ruining flower beds, and eventually dropping waste everywhere, leading to his placement in the lab.  

Personality

  • Cheeky, arrogant, and short-tempered. Prideful. Thinks he is the cutest in the world and looks down on all other beings. Apparently, he thinks his ears are his best feature. He mistakenly believes he'll be forgiven for anything if he says it cutely. He cannot forgive anyone who harms his cute self, but when he feels his life is in danger, fear takes over.  

Likes: His own slaves, beings who follow orders   Dislikes: Being treated roughly, being told he isn't cute, others being doted on more than him, having his ears grabbed or tail squeezed, pain
