@CountDankulaTV Finally, some high quality education

@CountDankulaTV What if I add a box of chocolate?

In Eastern and Little Nature Deity, her hair returned to a bright brown again, and is overall short. The triangle-dot pattern is replaced with a dotted stripe.

The necktie is also yellow this time.

In Touhou 15, Reimu's hair became black again and her hair mostly returned short, save for two long strands with her hair tubes.

The triangle-dot pattern shows more often here.

Same goes for Reimu, the "protagonist" of the series. In Touhou 6, she had short black hair, wait a plain red ribbon.

Her "signature" hair tubes are completely absent.
