フランちゃんの好きなアガサ・クリスティ作品から歌をもってきたよ

Ten custard puddings were derivered to Flan-chan;
One was gone into the darkness by Rumia and then there were H.

H custard puddings came close to the lake;
One was frozen and cracked by Cirno and there were eight.

Eight custard puddings were crossing the lake;
One disappeard in mist by Dai-chan and then there were seven.

Seven custard puddings passed through the gate ;
One overslept with Meiling and then there were six.

Six custard puddings reached the library;
Koakuma poured hot water on one "for you"and then there were five.

Five custard puddings read books;
One wore puffy Victorian pajamas of Patchouli and then there were four.

Four custard puddings bouncing softly;
Sakuya-san used one for bust pad and then there were three.

Three custard puddings rushed toward the mistress;
One was guarded charismatically by crouched Remilia and then there were two.

Two custard puddings came across a shrine maiden;
Reimu confound one with replica and then here was one.

One custard pudding left all alone;
Marisa bought it for a coin and then there were none.

元曲みたいに韻をふんでなかったりプリンにsをつけていいのか分からなかったり
大ちゃんの順番が遅かったり咲夜さんが2つ使わなかったりとおかしいところはあるけど
フランちゃんは気にしないよな
