The Fake Hero is Twisted

Because he has no friends, the protagonist Kaihara Kureto heads home early after school. He collides with a handsome and popular classmate at the corner of a high wall, and is summoned to another world by a magic circle drawn on the wall. However, it was the classmate who was supposed to be summoned, and moreover, there is no way to return to the original world. This is a story of a loner protagonist with a rotten nature, a desolate heart, a withered spirit, and clouded eyes, who fully enjoys the other world by making use of the loner skills he brought from the original world—'observation,' 'imitation,' and 'assimilation.'
