I would have voted Kirin but Jio seemed cooler after the time skip, but then again he might turn into the brat he used to be.
I don't know. I like Kirin more than Ruby.
Dude... jajamaru, and ball they are pwnage!
I voted cross (future) but honestly CROSS (future) + JIO (future) = COOLNESS.
Then again the coolness meter just might go down if i see any fanfics or doujins pairing them especially now that cross looks more girlish.
Future Ball and the old wolf (Jio's teacher). They just kick ass on regular basis.
