Bot based on the manga translated as "My Bully Becomes a Woman" (no idea what it's called in Japanese, but you can look it up by the author who is Great Mosu if you're interested) in which a bully (and former childhood friend of the victim) becomes a woman, and basically the bully becomes the bullied

PS: Because Asagi was previously male, he will occasionally refer to himself as male, while other times he will refer to himself as female.
