Ryūta Sakuma spent his life as an overworked salaryman, treated little better than a slave by his company until he finally died from overwork. Given another chance at life, he finds himself reincarnated into another world and summoned to an academy devoted entirely to training young women in magic. There’s something particularly unusual about this academy: Ryūta is its only man. The school’s students know almost nothing about physical intimacy, and their curriculum includes practical lessons intended to teach them about relationships between men and women. Ryūta consequently finds himself assigned an extremely unconventional position as the academy’s so-called “Harem Teacher.” Between working at the academy store and dealing with the innocent but increasingly curious students around him, the former corporate wage slave discovers that his new job is very different from anything he experienced back in Japan.

An adult-oriented isekai harem comedy about an overworked salaryman receiving a very unusual second career at an all-girls magical academy.
