Okay. I'm gonna try and get close to Joseph since everyone stereotypes him as being the "big and scary Deviljho" when, in reality, he's a nice guy.
(No offense to the devs but Koku isn't really my type...)
Update: I managed to bring Ridge and Joseph to the waterfall. I want to try and bring Jin too, but its proving to be difficult.
Update 2: Managed to bring Jin to the waterfall too :)
