原曲：凋叶棕 《喻》——
《タイド・コラプション (原曲：阿礼の子供／ジャパニーズサーガ)》
《揺レル鈴之音 (原曲：佐渡の二ッ岩)》
衣服用了bk的设定，算是三次创作。

Inspired by What-Ifs by Diao ye zong ---
"Tied Corruption" (original: Child of Are / Japanese Saga)
"The Sounds of the Swaying Bells" (original: Futatsuiwa from Sado)
The costume is from the album booklet, so this counts as a second-order derivative work.
