Something to do with that CGI movie that was in the Tekken Hybrid pack. All I know is it has something to do with a boy in their class.

xiao likes alisa but alisa dislikes xiao. also im not so sure how much netsu synergy actually matters since i see a lot of people playing heihachi/devil jin and they hate each other. idk if its just the fact that they're clearly 2 of the best characters in he game or if its really not that big of a deal.
