"Number of allies" excludes the primary members themselves, right? So Baku can bring in Kaji, Hachina, Marco, and Kyara? At least, assuming he has any sort of contact with Kyara.
I love Midara's character, and he probably loves the current situation where he's forced to involve the leader in a game, especially against 2 extremely powerful individuals. I wonder what setting he'll post the Ban within?
Everything seems to be happening within such a short time frame, the whole deal with Makuro and (younger?) Nowa should have been occurring during the KY Declaration, and that was only a few days ago in-universe. It makes sense considering Baku can't really be sitting around after taking over the L-File, or else he'll get trapped by some other Kakerou members without expecting it (unlike the situation with Ranko).
