My Hero Dungeon Academia

My Hero Dungeon Academia ( Hiatus ),

The world has undergone massive changes after the appearance of quirks, one of these changes is that dungeons have started appearing in cities all over the world. Heroes would often go into these dungeons so that the monsters inside are not released and harm the people. Mach is just like any other kid, but he would go into conquered dungeons to harvest materials for the government. However while he is in the dungeon something that has never happened before happened: a monster rebellion. The monsters inside had assembled to get outside and killed everyone in the dungeon except Mach, who miraculously awakened a second quirk saving his life. This quirk is no one never seen before: he could control or tame monsters! He will use his powers along with the system entrusted to him by the first monster he tamed.
