The theme of Kaguya Houraisan, the fleeing princess of the moon.
The Imperishable Night incident was used as cover to allow her to escape from the moon to Gensokyo.
Her Last Word Spellcard is insanely strong, and takes quite a bit to clear as a human.
According to glorious fanon, she's a Hikkikomori.
Her rejection of Mokou's father resulted in his suicide, and the long running feud between the two girls.
