waifu wise, Id say
<spoiler=Fuuka&Chihiro/Persona series>http://www.digitaldevildb.com/images/characters/persona3/yamagishi.jpghttp://i112.photobucket.com/albums/n199/kara_fox_girl/ChihiroSmile.png
Because they're both girls I would find myself enjoying in their qualities were they real (and chihiro reminds me of my former gf)
Or

mostly cause shes very lovely, and the ways he sings

Or
<spoiler=Aoi Ren/source unknown>http://cdn.myanimelist.net/images/characters/2/122161.jpg
No idea where shes from, and the only reason I saw her at all is a friend used her as a close likeness to what a D&D character she wanted to be would look like. No idea how she knows who Ren is either.
Real wise...
well, real wise I dont have an ideal girlfriend, cause if I did, it'd be very creepy and not healthy since the girl in quesiton was a former GF who passed away and i dont need to go spinning back into that after i got myself out of it in my senior year of highschool.
However male wise, if I was willing to swing that way (not entirely committed yet):

whos also the person I once picked when asked who I would pick to portray me in a movie about my life.
