Atl

Atl is an Aztec girl who works in a circus alongside her massive horse, Yukiwa (雪輪?). Atl was born in Mexico and was orphaned while living in Texas with her family; when she prayed to the Aztec god Quetzacoatl, she summoned a Yoi in the form of a horse that could also become a dragon. Since she had heard from some samurai stranded in North America about Japan, she decided to go there in hopes of finding a peaceful home.

However, Atl was reviled for being a foreigner, and had to artificially tint her bronze skin with makeup to pass for a Japanese person. She and her horse Quetzl (whom she called Yukiwa) performed together in a circus, until her status as a foreigner was revealed. After this, Genbatsu arranged for her to be a ward of the geishas he knew in the red light district, although she herself would not become one.

For reasons that are never fully explored, Atl is able to see Kumoshichi, and is able to correctly identify him as a Yoi despite his human appearance. No one other than Yukiatsu is able to do so.
