ナゾカケ (Nazokake)

Background
The song was originally sung by Hinata Haruhana. Like it's answer song Nazotoki, it was illustrated and composed by the same persons.

The song was based on Hinata Haruhana's story ''Umi ha sono nazotoki wo nozomu noka? ''(海はその謎解を望むのか?), however, the "full" version of Nazotoki uploaded on June hinted it was a "different" version, similar, but not the same. This applies to Nazokake as well.

A Rin Sweet version along with a new arrangement can be heard on Hinata Haruhana's Mechanical Mystery album.

Japanese and Romaji Lyrics
