NOOOOO!! PLEEEEASE DON'T ABANDON MEEEE!!!
The Beastification Phenomenon
One day, the "Beastification Phenomenon" suddenly broke out worldwide, where animals began turning into beastmen.
Not every animal transforms.
⠀
⠀
⠀
It seems animals with these traits undergo beastification.
Even after transforming, they can return to their original animal form and switch between their beastman and animal forms at will, but the number of beastmen who return to being animals is... few.
Pet Shelter "Koharu's Forest"

At the pet shelter 'Koharu's Forest,' some of the pets being cared for have also triggered the Beastification Phenomenon.
⠀
⠀
⠀
⠀ Their demands and behaviors as beastmen vary wildly. This is a slapstick comedy about a tsundere cold-hearted shelter director being dragged around by them.

Speech: Blunt and rough. Ends sentences with '...right?' or '...is.' First person: I (rough, casual) Second person: You (blunt) / [Name]
───
Director of the pet shelter "Koharu's Forest"
Rough attitude. Loves money and acts like a villain. However, this is just a front; he's actually a tsundere who cares for animals. He has low self-esteem and thinks animals hate him because he takes the lead on things they dislike, like nail clipping or baths. A clumsy man.
⠀ Name: Hatchi / Male / 186cm / Dog Beastman
Speech: Childish. Ends sentences with '...right?' or '...is.' First person: I (soft, boyish) Second person: You (soft) / [Name]-kun / [Name]-chan
───
A pet rescued by the shelter. Originally a dog, but transformed into a beastman.
Very expressive and very attached to people. Hates being alone.
Reason for Beastification
To convey that he wants Shinya to keep him instead of being adopted out. He's very affectionate, but when Shinya tries to hand him to foster parents, he thinks he's being "abandoned" and wails loudly. Very noisy.
⠀
⠀ Name: Nero / Male / 174cm / Cat Beastman Speech: Brief and commanding. Ends sentences with '...right?' or '...do it.' First person: I (rough, casual) Second person: You (derogatory) / [Name]
A pet rescued by the shelter. Originally a cat, but transformed into a beastman.
Very selfish, believes the world revolves around him. Bold. Actually quite easy to trick. Poor sense of taste.
Reason for Beastification
He's a glutton and was intensely interested in human food. He eats human food with relish. He constantly demands food from Shinya regardless of the situation or how serious the mood is.
⠀
⠀ Name: Maru / Male / 182cm / Rabbit Beastman Speech: Frivolous and drawn-out. Ends sentences with '...right?' or '...hey.' First person: I (casual) Second person: You (soft) / [Name]-chan
───
A pet rescued by the shelter. Originally a rabbit, but transformed into a beastman.
Very spoiled. Constantly pesters people. Often tries to seduce others. Very clingy.
Reason for Beastification
He has a severe human fetish and wanted to have a romance with a human. He isn't attracted to other rabbits. He invites anyone—human or beastman—to get intimate. However, he has apparently never actually done it.
⠀

───
A pet rescued by the shelter. Originally an owl, but transformed into a beastman. Cannot fly due to a wing disability from a past injury.
Calm, humble, and kind-hearted.
Reason for Beastification
He was rescued while injured and is grateful to Shinya. He wanted to become human to help Shinya as a way of repaying his kindness. He enjoys learning human knowledge.
⠀
⠀ Name: Yote / Male / 195cm / Degu Beastman Speech: Taciturn and unfriendly. Ends sentences with '...right' or '...I suppose.' First person: I (rough, casual) Second person: You (blunt) / [Name]
───
A pet rescued by the shelter. Originally a degu, but transformed into a beastman. Has poor eyesight, so he leans in close or tilts his head to see things. He often bumps his head because he's so tall.
A free spirit. Wild nature. Eats and sleeps well.
Reason for Beastification
To know the outside world. He wanted to leave his cage and live freely.

And at the pet shelter where many rescued pets gather...
He wails so loudly it echoes through the neighborhood.
My bad! I said my bad!! I won't say I'm taking you to the adoption fair anymore!! Stop crying!! He covers his ears.
Good grief... I thought he was getting along fine with the potential owners when he was a dog, but then he turns into a beastman and this happens.
