"Netsuai Hakkakuchū" was one of two unpublished songs, the other being "It Was You," a ballad written by American songwriter Burt Bacharach.

[3] Sheena performed the song at her Tōtaikai series of concerts in November 2013, which later had a DVD release in March 2014.

[8] A short version of the music video for "Netsuai Hakkakuchū" was uploaded in early November 2013, and reached 100,000 views in three days.

[9] The music video features Sheena playing two characters: Rinnko (RINN子) and Linnko (LINN子), members of a fictional idol group called Rinrin (凜凜).

Linnko, wearing dark leather, bends down to look at Rinnko's body, and begins to move her arms in martial arts-like stances.
