Not too sure on the hands to the left and the bottommost hand on the right. I'm personally guessing detached sleeves is Reimu and long sleeves is Sumireko, leaving Marisa on top since she's usually paired with Reimu.

pretty sure the other hands other than byakuren are ichirin, shou, nazrin, and murasa.

Yeah, the bottom left one doesn't have Reimu's red in-lacing on the sleeve.

Changing tags.
