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 you pay for the next drinking 
party I'll let you off.
سأدعك وشأنك إذا كانت حفلة الشرب التّالية على حسابك
Wenn du für die Getränke beim
nächsten Meeting zahlst, vergeb ich dir.
Aunque te perdonaré
si pagas la bebida de hoy.
Aunque te perdonaré
si pagas la bebida de hoy.
On fera un point
sur la compta du bar !
Ma chiuderò un occhio
se offrirai tu alla prossima bevuta.
A menos que você pague a próxima
 festa que sairmos para beber.
