Momiji Inubashiri

Momiji guards Youkai Mountain, much like a dog would guard its territory or marked areas. Momiji is friends with Johnny Joestar, and Franz, a member of the forgotten who travels in and out of Gensokyo through Don's mysterious gapping abilities, which is why he opens gaps during his conversations with Saikou, or during dinner with Saikou and Ashley (Pre-Strikes), or while he is doing the laundry. Don does this to let Franz in so he can see Momiji. Momiji is a white wolf tengu, and uses her highted senses to guard Youkai Mountain. . She enjoys spending time with her friends on the mountain during her free time, and whenever Franz is around, she and Franz guard the mountain together. Momiji senses that something is wrong with Nathan, and she too is aware that Nathan is a celestial wolf, sharing this with Seiken.
