She is, and for her birthday Tsukiyama buys her a kit of rainbow hair dyes. He spends the entire day helping her dye her hair appropriately.
Kaneki and Touka (meaning Touka) buy her makeup.
Naki makes sure she wakes up in a sea of glitter.
Nishiki teaches her the science behind rainbows and gives her a prism as a present.
Irimi and Koma buy her a dress.
Shio, Rikai, and Yusa make her a flower crown.
She’s never had a birthday party like the one spent in hiding in the 24th ward, surrounded by people who love and accept her.
