[@Double] Isamu sent him a friend request. If he Takatora really wanted too he could come back. Up to you though, you could skip out on it, no pressure. You'd just be on your own till another chance would arrive for everyone to meet up. I.E. tomorrow or maybe if Takatora waited for them in the lobby somewhere. 

Hell for all I know, Takahashi and Miyuki might leave him or something.
