A Shaman Can't Become a Hero

On that day, the 41 students of Class 2 7 of Private Hakurei Academy are summoned to a magical other world, different from Earth, due to an incident that occurs without any warning. They descend into a vast dungeon, and with the power of divine protection, "Calling," they head towards the deepest part of the world, where there is only one way to escape. Some bravely, some freely, and some treasonously aim to conquer the dungeon. However, there is one student here who has found a calling without any combat ability. Attendance number 19, Kotaro Momokawa. A small, slender boy who belongs to the literature club has no magical powers, no talent for swordsmanship, and no blessed physical abilities, but relies solely on his vocation of being a magician, and chases after his classmates who have powerful powers - his survival instincts are fully activated! Ultimate parallel world dungeon survival. A beautiful yet gruesome battle royale begins, where people believe in each other, love each other, betray each other and kill each other.
