When Dance of the Moon Rabbit started to play during Reisen's appearance, I instantly ahegao/mindbreaked and Reisen became one of my most favorite Touhou characters.
Comment from link: As if the links to Touhou and Umineko couldn't stretch any further... Now it's sealed with Reisen (II) having this played during Koishi's Heart Throbbing Adventures... In a very, VERY big way~ <3
