I didn't do a pencil sketch for any of these so that explains why they don't look good.

Characters from left to right (starting from the top):
Suwako Moriya
Random-no-named-person
Time Chaser (obligatory Fan tag. [also I hope this doesn't turn into the next Chance thing... ._. Knowing me though, it probably will...])
Nitori Kawashiro
Yuyuko Saigyouji
Kaguya Houraisan
Meira.... Does she even have a last name xD

Also ignore that paper in the back...
