i just started watching jibaku shounen hanako-kun (toilet bound hanako-kun is the english title). it's pretty good so far! i got hooked so am now reading the manga while i wait for new episodes.
i know the title sounds kind of weird, but it's loosely based on the urban legend of hanako of the toilet, a ghost who's bound to a toilet in a school. the main themes in the anime are supernatural, humor, action, and a little romance. i would compare it to ao no exorcist, so if you like that, you might like this.
