Rouge Poison God

In the modern world, humans are summoned to a tower to become hunters, fighting demons. However, only students below the age of 18 and with a stigma in their eyes can be summoned. Yet, it's unknown who will get summoned, and only 1 out of 10 humans can be selected as a potential candidate to become a hunter in the tower. Among them is Odion, a seemingly worthless orphan consistently victimized by bullies in his previous and current schools. Even weaker students bullied by others bully him. One day, his first childhood love, Kimiko, disguised as a surprise, asks him to come with her. With his foster father, she plucks out his stigma eyes, rendering him blind and betraying his love. However, this betrayal opens a new world for him, leading him on a path to become the first mortal to reach the level of a god.
