Grim Reaper and Four Girlfriends

Kaoru Minaguchi is a " no-lifer" who sucks at school, can't play sports, lacks any real talent, definitely doesn't have a girlfriend, or even a remote desire to change his ways... until a certain grim reaper pays him a visit. Turns out, she's a reaper of " no-lifers" and if Kaoru can't find a way to become a true " real-lifer," he's as good as dead...!
