Why Should an Invincible Man Fight for Himself?

I woke up as a tabby cat in a parallel world, and the System I activated turned out to be a traitor.

It's bad enough that my human makes me work every day. The damn System is even called the Human-Raising System.

So who's the Host here, huh?!

At least leave some benefits for me! All you do is come up with flashy stuff to benefit my human!

System! I swear, if you don't give me something good soon, I'm cutting ties with you!

Huh? What? A Human Ability Enhancement Manual?

Oh my! This is the good stuff!

P.S. The protagonist definitely gets benefits too.
