This is an amazing pic and I really like it. I have one question tho; why Alice? The rest make sense, Aya = fastest, Suika = strongest, etc., but is Alice the most intelligent/strategic? Dexterous? In the end its a minor gripe.
On the left are Reimu's 3 partners in Subterranean Animism: Yukari, Suika, and Aya. On the right are Marisa's 3 partners in Subterranean Animism: Alice, Patchouli, and Nitori.
