My husbando is Agatsuma Soubi, a main character of the shounen-ai (or for those who don't know that term, it's yaoi, but without the sex) anime/manga series, Loveless, along with Aoyagi Ritsuka. He's the ex-Fighter of the Beloved pair, who ended up with Ritsuka in an unofficial pairing called Loveless. He's extremely strong in the spell-battles against others (which is more of a battle of will and wit), but only when he's close to his Sacrifice/loved one, otherwise he's no stronger than any other Fighter. Despite his docile attitude towards his Sacrifice, in reality he's strong, protective, morally just, and very kind. For me, there could be no better candidate, though I could do with less weepy/docile moments (even though it is a bit cute). :P
For more information on Fighters/Sacrifices and the meaning behind the names of pairs, check out the anime or manga, or of course google is your friend.
