Okay, 1 of the B ranks have been approved: Yuki Setsuna
another 4 people want the 3 left. They are (as far as I'm aware)
Tsumi Buredo
Dunkelzahn - Daisetsu
Dirge - Ookami, Senzo
Neiro Kagakusha - Inuzuka, Hagane
So this is a case of first come first serve. In the case of a tie in terms of completion time, I'll give it to the best app. This will also make you all hurry up, so have fun XD
