Hajime Aoyama

Hajime is Satsuki's neighbor. He is always strong and courageous to help defeat the ghosts, but though he says that this is very brave, he is actually a coward. Despite this, he is one of the most reliable of Satsuki's friends and has saved her on more than one occasion. Hajime also has a naughty habit of flipping girls' skirts, and his constant victim is no other than Satsuki. This results in frequent comic moments. Throughout the anime, it seems that Hajime and Satsuki develop mutual crushes on each other (not that they'd admit it).
