No, that is not a "What does not belong" puzzle. XD

Anyway I'm having a hard time deciding between those three of what to start reading/watching. From what I've heard Chobits is apperently like Love Hina for girls and DiGi Charat may be a bit too cute. I haven't heard a lot about Shakugan no SHANA, but it has a red head with a sword. So I'm kinda leaning towards SHANA, even though I like Love Hina I don't know what my friend meant by it was aimed toward girls.
