seems rinnosuke has a bit trouble with his harem life.
or im to dumb to know what they mean in this picture.
there jealouse(?) of them? and saying all the bad points of them so he should hang more with shiki and kasen instead of marisa and reimu.

Shiki has problem with Marisa stealing things. Kasen has problem with Reimu and her laziness.
Direct lectures will not work for sure, so they pass the speeches to Rinnosuke.

Looks like he's taking the heat...

No, I think it's the other way around--Kasen is trying to hook-up Rinnosuke with Reimu, and Shiki is pushing for Marisa.

Say what happened to Kasen's bandages?
