Hey,

So I've been recently trying to find a manga/possible anime that i read a few years back and after a good few hours of Google search i still can't find it.

Basically the manga is about a main character who is male in a school but ends up in a different world during a set time period, during this time he meets a weird as masked dude and finds out there are strange monsters around this world (can't remember if the school is still part of the other world he enters) he survives by hiding first of all and then later finds out he has a game like ability that allows him to enter a room and play a game with a butler/judge like character within this room if he wins the game he is able to do something to a person or monster, while slowly finding out about the masked guy and the alternate world. He also finds out he's not the only student that is pulled into this other world.

Not sure if this is enough information to go off but i just can't find it on my own, so here's hoping someone knows what i'm talking about.

Thanks.

Kyokou no Ou?
