Well, it's just a youth story with Nioh boy as the protagonist?
A little bit of fantasy?
How about the beginning of the story? This is a murder caused by a computer. A cat with stunning appearance ran out of the computer of a young Nioh boy, and then a series of daily tennis and cat-raising events appeared.
Well, I forgot to mention, this is someone else's cat, its name is Dilumon.
Asking for leave: I feel like I can't update when I'm going home during the National Day holiday_(:3∠)_. I'll definitely resume updating after the holiday! ! !
