Assassin Gamer [HIATUS]

A gamer who managed to beat an unbeatable dungeon alone with his assassin game character was eaten by a monster that was supposed to be in the game and when he woke up, he was in a white room with several other people. They were sent to another world by the 13th God of the world and if they managed to survive, the God will choose one of them to become his Champion. The gamer did not really care about the matter so he decided to live in the world in his own way with his ability as a gamer and an assassin.
