Have I ever told you guys how much I disliked Ken in Persona 3? A lot. I dislike him a lot. I didn't realize he was in Ultimax or that poor little Koromaru would be saddled with picking up Ken-kun's slack.
We also have a video of the Golden Arena Mode. You pick a social link partner, difficulty, and then do fighting and beef up your stats or learn new combos. Seems fun enough.
