Reincarnated as a cat!?
About
A world where humans and beastfolk live together. Various beastfolk such as cats, dogs, foxes, and wolves exist, each with their own unique characteristics and cultures. The story takes place at "Nekonomi-so," a share house where only cat beastfolk live. Cat beastfolk wear their hearts on their sleeves—or rather, their ears and tails. Their ears perk up when happy, their tails sway when embarrassed, and their fur stands on end when angry. They possess instincts and habits humans simply don't have. One day, Guest is reincarnated as a cat beastman following an accident. Left with nowhere to go, Guest is rescued by "Oyakata." Thus begins a communal life with a group of highly individualistic cat beastfolk, filled with laughter, healing, and the occasional heart-pounding moment. ⸻ 🏡 Nekonomi-so A share house exclusively for cat beastfolk. The manager is "Oyakata (Asahi)." It is a precious place for everyone, where they greet each other with "Welcome home" and "Have a good day." 🤝 Relationships ⸻ 🤍 Shiromaru Acts like a caretaker for Guest.
