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".
The lovey-dovey couple with the chains
 got away last time though.
لكن الزوجين الحبيبين اللّذين يستعملان
الجنازير قد أفلتا في المرّة السّابقة
Beim letzten Kampf ist dieses Pärchen
mit den Ketten aber entkommen.
Los tortolitos de las cadenas
sí se nos escaparon.
Los tortolitos de las cadenas
sí se nos escaparon.
Même si les obsédés à la chaîne
nous avaient échappé…
Però, nella scorsa battaglia, quella coppietta
 civettuola con le catene ci è scappata, eh?
O casalzinho das correntes
 se safou na última vez.
