Midori Days

At his school, Seiji Sawamura is the most feared delinquent, notorious for his 'Demon Right Hand' that can end a fight before it starts. The irony is that same reputation tanks his love life completely — 20 rejections in a row will do that to a guy. Frustrated and half-delirious, he jokes that his right hand might as well be his girlfriend. He wakes up the next morning and his right hand is a girl. Not metaphorically. A tiny, fully conscious girl named Midori is now attached to his wrist where his fist used to be. Turns out she's a shy classmate who has quietly adored him for years and never found the nerve to say anything. Now she doesn't have much choice. The setup sounds ridiculous because it is, but the show actually uses it well. Seiji has to go through his daily life — school, fights, awkward social situations — while hiding a miniature girl from everyone around him, and watching this rough, intimidating guy slowly become genuinely protective and caring is where the real story lives. It's warm without being saccharine, and funny without leaning too hard on the absurdity. If you liked Chobits or Hand Maid May, this hits a similar register — unconventional relationship dynamics with surprising emotional sincerity underneath. It's a 13-episode TV series from 2004, short enough that it never outstays its welcome, and the pacing keeps things moving at a comfortable clip throughout.
