I was hoping for a Natsume Yuujinchou kind of anime. If you don't know Natsume Yuujinchou, go watch it.
Sadly, this is nowhere near it, it somehow takes the ghost thing and tries to make it more funny in a school setting, with ghosts that are visible on photos and mirrors for everyone and almost no one is creeped out by it.
Although I do enjoy Slice of Life anime (it's pretty SoL-ish) and this one is not a terrible anime, it really is incredibly boring.
3 episodes in and I can't watch more of it. I enjoy much worse anime better than this and that surprises even me.
