Can't remember/find manga name. Similar artstyle to Dandadan's manga. *SOLVED: Nejimaki Kagyu*

Story goes about a young man getting a job as a teacher in a only women school. Gets bullied a lot by the girls (horrible girls, one piece villan type looking girls) The teacher's childhoodfriend(? is there and protects him from the girls, with martial arts superpowers (thats the manga combatstyle) The girl is short, has dot eyebrows, and silver hair(? with a long and thin single chinese or asian style pony tail . (See photo for reference)
