This is one of the best anime I've seen in a long while. Now for my review
Story:
This is standard school plagued with spirits fare for the most part. The Holy Student Council, of which Haruto, Kazumi and Mutsuki are members of, is tasked with keeping spiritual harmony at their school, and they accomplish this by going after errant ghosts and helping them either move on, or at least stop their foolish behaviours.
Although the concept of some ruling body policing otherwordly beings isn't new, this anime pulls it off in a strict school setting, and in just 12 episodes, bonds are formed within the group through their misadventures that's a plain joy to watch. Haruto, being the unwilling President of the Holy Student Council, is able to summon all 7 school spirits at his choosing (yeah, whole new meaning to having school spirit). Kazumi and Mutsuki are son and daughter of buhddists/shintoists respectively, and all three houses for a triangle which grants Saito High its unusual paranormal phenomenoms.
Art
Eh, not much to say here, the art is standard for anime, although the sequence of summoning the spirits is fun to watch, reminiscent of Sailor Moon (yes, you enjoyed it when you first saw Sailor Moon and her transformation, admit it) and a little bit of fan service goes a long way in anime like this, which are usually overlooked in favor of more high profile paranormal police anime (Yusuke, I'm looking at you!)
Sound
There aren't really that many special sound effects or much, but a particularly funny and enjoyable part of this anime is the summoning sequence, in which Haruto says "Welcooooome" (yes, in engrish) and every episode except the sixth, which ends in a splendid "OH MY GOD" (also in engrish) for a variety of reasons.
Character:
It is interesting to see the interactions between Haruto and his fellow Holy Council members, seeing as how he just wishes for a normal life. These interactions add a great deal of depth and conflict to what would otherwise be a happi-go-lucky anime of high school students having fun chasing after various ghosts
Overall Enjoyment
Lately I've been seeing a lot of short anime, like BPS, Maburaho and some others, but this one is the most that struck me, as it has real character development, interesting side stories and a lot more I don't wish to spoil. So hurry up and watch this anime! You'll be glad you did!
