Did you watch Shakugan no Shana or Burning Eyes of Shana? Yikee it's so romantic and a kind of ecchiness (but it is not fully ecchi anime).
I wonder what gender suits for this anime, because it is for shounen or shoujo.
Well, please post some suggestion for this anime, if it is good or bad for your taste. And, also please tell if this is SHOUNEN or SHOUJO anime.
