「The Other Side of the Wall」Void_Chords feat.MARU　
（Hear me, I say. 　Cross the wall. ）　
Can you feel that nothing turns you around? 　
Like a gear in sync inside a clock. 　
Who can be sure of how to make it work? 　
Recognize, inner sight, gotta stay alive. 　
I'll never be deceived, I'm a girl that sees through lies. 　
'Cause I know, know it all, Gonna fly so high. 　

Get across the wall. 　
What a waits, and what can it show me now? 　Smack it down. 　
Get across the wall. 　
Break away, and then let them catch me say, “Don't let me down.” 　
On yeah, when the clockwork moves and starts to shine (you got to find ). 　
Forever let it blow, carry out, show the way! 　Blast it of right.
