A boy can only do so much in this big world. A boy is just a little more than a kid. What much can a boy who only play games do?
That would depend on what game they play and who pays the price for it.
Synz Yamikage-Nieve is a Japanese boy living a rough life as a halfie. He likes games and comics. He reads fanfics and webnovels. His social life is nonexistent. He has issues.
He was offered a part-time job of saving worlds.
He accepted the job in spite of the unlikelihood of it NOT being a scam.
...it wasn't a scam.
