Shi-kuretto Karuma Serenade
[Secret Karma Serenade]

The lyrics for this aren't featured in the lyrics booklet; however, a snatch of it is played in the end of Order 13. ShadowcatKirara took a stab at transcribing them:

Hoshi ga nagareru
Tsuki ga kagayaku
Yume ga Seurametum
Hoshi ga nagareru
Tsuki ga kagayaku
Alkara Seurametum

Fansubs translate those lyrics as follows:

The stars are flowing
The moon is shining
The Seurametum of Dreams
The stars are flowing
The moon is shining
Alkara Seurametum
