骸骨楽団とリリア (Gaikotsu Gakudan to Lilia)

Background
This song was uploaded to Nico Nico Douga on June 18, 2011. It is currently Tohma's most popular work, Envy Catwalk, another popular song of his, only slightly behind in view count. The song has been featured in the Exit Tunes compliation Vocalocluster.

The lyrics, themselves, are rather nonsensical, and the meaning depends on one's own interpretation. A popular assumption is that it is about a girl singing to the boy that either chooses to ignore her or cannot hear her.

This song is featured in the game Hatsune Miku Project mirai 2.
