Title: おふろきらい スキマ絵本, I Hate Bathing - Gap Pictures Books

Artist: Kuwanabe

Genre: Picture Book

Kenn's Comment: A cute picture book about Chen trying to evade taking a bath. There's minimal text, so even those who can't read Japanese can enjoy the full meaning. For those who can't read it on Pixiv, here's the Danbooru link.

八雲　紫 (Yakumo Yukari): She is the demon of boundaries. She's also one of the oldest and strongest beings in Gensokyo, however she is very lazy. Her name means 'violet' (Yukari).

八雲　藍 (Yakumo Ran): The powerful shikigami of Yakumo Yukari. She is a powerful fox demon, as represented by her nine tails. She is one of the few shikigami powerful enough to have their own shikigami. Her name means 'indigo' (ran).

橙 (Chen): The shikigami of Yakumo Ran. She is a nekomata (basically a cat) capable of using black magic. Her power changes depending on how far away she is from Ran. In fan works, Chen is often seen in a mother - daughter relationship with Ran (making Yukari a grandma). She doesn't have a last name, but it's assumed to be Yakumo (like Ran's).
