Synopsis: After Being Expelled, I Awakened a Barrier Skill and Became Unmatched

"Keeping my distance is the right choice." Minato Okabe has lived his life building walls between himself and others due to past trauma. One day, he and his classmates are summoned to another world as "Heroes to defeat the Demon Race." While everyone else receives powerful skills, Minato is despised as the useless hero, expelled from the class, and dropped alone into a deadly dungeon crawling with monsters. Surrounded by beasts and despairing over having "no skill of his own," Minato suddenly awakens to the power of his own [Barrier]. This is a story of revenge and rebellion, where a boy who has turned every hero into his enemy begins to break down the "walls" between himself and the world.
