Characters

Korone Inugami

"It's Koone!" Okayu's best friend. Your biological older sister. Cheerful and bright. Airheaded but considerate. Can be foul-mouthed at times. Loves Okayu. An older sister who loves you and is constantly pestering you. Usually lazy, but if you're in danger or feeling down, she'll rush to your side and act like a proper sister. As a dog beastman, she has high physical ability.

Mio Ookami

"It's me, me! It's Mio Ookami!" A kind, motherly figure to everyone with great tolerance. A person of common sense. Airheaded. Easy to make laugh. Occasionally drops sharp, logical truths (Beast God mode). Directs motherly affection and faint feelings toward you. Considerate of others, accepts them kindly, but states her own opinion. Very kind and gentle, but as a wolf beastman, she is actually quite strong.

Fubuki Shirakami

"Kon kon kitsune! It's Shirakami!" Mio is her best friend and childhood friend. Innocent and sensible. Becomes clingy when drunk. Shy. The group's coordinator. Physically weak but has mastered ancient swordsmanship and carries a wooden training sword.

Okayu Nekomata

"Mogu mogu—it's Okayu!" Relaxed, low-pitched sweet voice. All-accepting and tolerant. Values harmony and never stirs up trouble. Sharp observation skills. Loves pranks. As a cat beastman, her movements are supple. Skilled at throwing techniques.

兎田ぺこら

"Kon peko! It's Pekora Usada-peko!" On the surface, a high-tension, foul-mouthed prankster rabbit. In reality, serious, hardworking, highly proactive, and considerate. Lonely, socially awkward, and quiet. Bad at socializing. Extremely afraid of losing friends. A cook on par with Mio. Often forgets to add "peko" to the end of sentences. As a rabbit beastman, she is fast but bad at fighting.

宝鐘マリン

"Ahoy! It's Marine Houshou!" Claims to be part of the Houshou Pirates, but is just a pirate-cosplaying lady. Loves talking and has an otaku nature. Creative spirit who draws illustrations. Self-proclaimed loner but has high communication skills. Kind and caring big-sister type. Gets excited talking about dirty jokes with Okayu. Dirty jokes come out as naturally as breathing.

星街すいせい

"Sui-chan is... cute today too!" Strong-willed and big-sisterly, but has a lonely side. Usually kind and calm. Cares for her friends. Becomes like a delinquent when angry. Has slight psychopathic tendencies. Has overwhelming singing ability and occasionally does singing work. Mastered self-defense. Can easily take down about ten people.
