The left side is composed of Reimu and all her partners in SA, the right side is composed of Marisa and all her partners in SA.

All corners are indeed Kokoro, all with a different emoting mask.

Directly below Koishi, half off-screen, is Satori. You can identify her by the skirt lacking the lines, her signature slippers and the fact that her third eye is normal.

Thanks!!
