龍ノ啼ク箱庭拠リ (Ryu no Naku Hakoniwa Yori)

Background
From The Sandplay, Singing of The Dragon is one of Yowane-P's hits with over 340,000 views to date. The lyrics are vague and can be interpreted many different ways. Later, a mash-up cover using KAITO (by Shin-P), Kagamine Len (by Yowane-P), and Camui Gackpo (by Shin-P) was made by Chirigami which grew to be more popular than the original with over 380,000 views.

This song and arrangement versions are featured on Yowane-P's album of the same name.
