In reply to the previous review,Too long? It should be Too short. You have obviously not read the manga yet, the manga have progressed way way longer than the anime. Lengthened ? Thats actually opposite. This anime is shortened on purpose becoz the anime have caught up on the manga. Dont know about your fetish but blame the author, shes the one who created Hilda rofl. Its a shounen anime with slight comedy, dont expect too much comedy at a shounen anime.
Anyway, this anime is a spectacular shounen anime with a slightly hint of romance. The comedy parts are smoothly delivered so that it would match the audience's taste. Too bad the show is cancelled coz of the past facing on the anime which made it catch up with the manga. Overall the show is not too bad, its been a fun ride.
If you want more of this anime go read the manga.
