I’m just going to throw this out there, in my own headcanon for Touhou, Reimu’s hair glows purple when she uses her Float ability at full power, at which point she simply “floats” away from reality, such as when she uses the spellcard “Innate Dream”.

Should we create a tag for this version of Reimu? On Pixiv they are already using 怨霊霊夢 to refer to this event.

Also, kinda had Yamiyo heno Prologue playing in my head when this scene came up.
