Thinknig about Chrono & Fate thing, I just realise something, Fate is going to be Chrono "Imoutou-Chan" and Chrono is going to have this cute/sexy girl coming up to him going "onni-chan". So if they hook up it's technically "Incest", but without the Genetic problem....
H-GAME!! KAAAAANNNNNAAAA!!!!
I'm all for it! Get lost Amy Fate-chan getting her "Onii-chan"!!
Chrono: Fate-chan, we can't do this, your my sister....
Fate: Demo, Onii-chan....Daisuki!...besides we are not related by blood...so its ok....
Chrono: Iiie..iiee...I...can't...must..resist......
Fate: Resistance...is..futile.....fufufufuuu.....
Chrono: Noooooooo!...oooh....ahhh....
