did he lose his power? i dont remeber http://www.mangago.me/read-manga/revival_man/mf/man...

I don't know if it's REALLY gone. He may think it's gone because the room is gone and he always revived in that room, remember? He always woke up in his apt. But the apt burned. So, that may be why he thinks he can't revive anymore. (I hope he's wrong.)
