Well ain't that nice, another Touhou x Seihou vocal that appeared in an official Touhou game (Touhou Hisoutensoku). This is a Dichromatic Lotus Butterfly arrange, it's Reimu's theme from Seihou Shuusou Gyoku if you haven't known. Sounds child-like if you'd ask me, those "la la la la la la" in some parts of the song made me swing my head sideways, loli-tastic tunes are indeed enjoyable.

No wonder, since the one who sung this is responsible for the ever famous Kero⑨destiny, Meramipop. And I never get tired of hearing that boot-like sound.
