Marry: Nakano Azusa (K-ON!!) She's pretty promising for a future since I get the impression she excels in school. She's freaking adorable- azuu-nyaannn! (I'd be lying if I said I wasn't thinking of any fetishes right now). Based off her character, she appears: kind-hearted, honest, considerate, and [insert nice person adjectives here]. To top it off, I want to play bass with a guitarist... especially if the guitarist would be my wife, haha (although I'd prefer Mio XD).
Fail Date: Furukawa Nagisa (Clannad) Okay, don't get me wrong, I love Nagisa as a character, but I've gone on dates with (too) shy girls before and it drains a lot of energy from me to try to initiate everything, set up a comfortable environment, and etc. If they're a little shy, no problem, I think it's cute and makes things easier, but Nagisa comes off to me as someone who would be too nervous about everything on a date -___-.
Sex Once: Misaka Shiori (Kanon) As soon as I read Shiori, the thought of, "Nice guy gets laid from cute girl for sincerely helping her out". I won't go into further detail about my thoughts, lol.
