Melina Accepted Me as a Person with Epilepsy

The background of the story is that a shady man who cleared Elden's Circle accidentally found a way to enter the new world through Lani's research. At this time, he completed all the branches, defeated all the main body BOSS, obtained all the spells, prayers and combat skills and props, and even mastered them to get new skills that are more suitable for him. He has all the power in him (he is awesome anyway)
