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".
I do not have the body of an 
elementary-school student!
جسدي ليس كجسدِ تلميذة مدرسة ابتدائيّة
Ich habe nicht den Körper
eines Grundschülers!
¿A quién llamas niña de primaria?
¡Como mínimo, de secundaria!

¡Como mínimo, de secundaria!
Chi sarebbe che pesa come
 un'alunna delle elementari?!
Eu não tenho corpo de 
alguém do fundamental!
