I was surprised! A bone fracture of Reni Takagi was announced formally. However, it was announced that she participated in a Toujinsai without a change.
I don't know why I assumed it was going to be a center stage. There was a pic about the feud between Kawakami and Hyadain that led me to beleive that I think. Maybe for Day 2, if that's when all the collaborations are taking place.
The Hyadain thing is supposed to be Friday at least...I don't know if he'd be there for Saturday as well since the promo video of the fake fight has Kawakami only yelling at him to be there Friday and no mention of Saturday.
