After the battle inside the Ziggurat, Chizuru and Hayate are horrified to find out that their victory would have cost Koyori her life. They agree to help Tazuna and Koyori, even though they're out of the fight now.  They tell the two of them that in order not to be found in the real world, they need to come up with a name to use inside the Ziggurat when they fight.  After a bit of thought, Tazuna and Koyori's new name becomes "Single Gear".
If she doesn't charge, 
and loses her power, she dies?
إن لم تشحن نفسها وخسرَتْ قوّتها، تموت؟
Es increíble que pueda perder
la vida si no se cargan,
Es increíble que pueda perder
la vida si no se cargan,
È inconcepibile che senza il Charge
perda le forze sino a morire,
Se ela não carregar, e perder
 os poderes, ela morre?
