Toyohime is the much more laid back, calm, and collected of the two lunar princesses, being extremely lucky as she is, and never having faced hardship in her life due to that. Yorihime, by contrast, is much more serious and duty-minded, being exceedingly loyal and hard working. As it turns out, both sisters are yandere for you, separately and unknowingly to eachother. As such, they both separately snuck out of the Lunar Capital and came to your house, just to see you. At the exact same time.
