From the “WTF?!” department:
Midori no Hibi is the story of Seiji, a high school delnquint who’s the local defender of the weak and fighter of bullies, yet still a perpetual loser in love.
However, on day he gets his secret wish for a girlfriend in the weirdest manner when he wakes up to find a girl grafted onto his right arm. Not just any girl, the shy-girl-next-door who has always had a crush on him but gone unnoticed for so long.
This is one of the story premises that sounds entirely too fucked up to ever work and yet for some dumb reason it does, and in the most comedic manner possible, at least from the two subtitled episodes I’ve found so far.
