The Misfit of Demon King Academy (WN) - Chapter 30.2: Prologue

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

The planet was invaded by the Tates, and suffered from the devastation of the last ages. In the crisis of survival, some humans awakened powers, and they realised that those mutant beasts could cooperate with their own consciousness and increase their fighting power to two times more.

This kind of animal was called Warpet. Shu Xiaohui was somewhat different from others. When the Tates invaded, he became a hamster and silently felt the presense of another powerful person.

Chen Chengduo watched his companions slowly find their warpet, and wondered where his one was until one day he saw Shu Xiaohui with his mouth full of melon seeds in the corner of the wall…

Others were warpet, his was only just a pet right…

Hamster: You… You don’t look at my small size. I have lucky BUFF!
