What are the various Bind Categories?

Have you tested Kanna's Hyper Bind? According to a Japanese blog I read before we got Kanna/Hayato hypers, it's actually like this:

Group 1: Demon Slayer, Demon Avenger, Luminous, Dawn Warrior, Ice/Lightning Archmage, Kanna's Hyper Bind
Group 2: Paladin, Xenon
Group 3: Kanna's Binding Tempest

Ah, no I haven't.

I figured since Kanna's first bind was in it's own category, the second one would be too, since I know the 2 binds can be used straight after each other.
That is actually pretty disappointing if that's the case.
