For what it's worth, the upper-left corner of the last scan, showing Pink and Black fighting Max Red, specifically brings up the possibility that the others could use the Ryusoul Calibur after enough training.

The already absurd amount of love Koh and Canalo get when it comes to merch has definitely hit a new high, though. I don't know if it's offensive on the level of giving Lupin X Keiichirou's big power up yet, but given that Koh just got a very cool looking final form with some major emotional weight behind it in the story, I think it would've made a lot more sense to simply have this be the "everyone else" power up to begin with.

Still, I can't say no to a good cape.
