Ginger, are you going to be editing a few parts of your character?  If so, I'll evaluate him afterward.

Yes, there is a fifth slot available for Midnight Squad.  It's not an ordinary team because it's not affiliated with any school.

The second senior team has Crimmy's senior, Onarax's senior, and Sho's senior, and an open slot, but it's tough to describe since it's only three reserved slots right now with no characters.
