Uruha no Sekai de Arisugawa

Arisugawa was raised in a chaotic household by a father who is a drunk and a brother involved in delinquency, leading her to develop a strong aversion toward men. She frequently faces unwanted advances, which she confronts aggressively, earning her the nickname "Arisugawa the Manhunter." After meeting a ninja named Kuro, she is transported to a different world and finds herself transformed into a man. In this new environment, she must work alongside Kuro to find a way back to her original world and restore her female form.
