From Exiled Rebels Scans:

Shina Ayumu is part of what other college students call “the flashy group”. However, where everyone thinks of him as bright, cheerful and always smiling, he is hiding a secret that only his high school classmate, Hayase Souta is aware of. Since their first year of high school, somehow Hayase has always ended up meeting Shina after a break up. So now Hayase sees Shina only as a big crybaby!

In Gensei, where the ghosts reside, a beautiful bartender and his partner, a black cat named Gin, operate a bar. Amongst those visiting the bar was Natsu (a mythical twin-tailed cat), who makes a living reporting gossip. Despite this, he lives a life in poverty.

One day, he meets a widely popular pornographer, Hyde (Tsuchigumo). While hoping to do a scoop exposing Hyde's mysterious private life, Natsu sneaks in as a housekeeper. However, where he thought he would find a story, he instead finds his own body exposed through punishment with catnip and adult toys――?
