Galko's skin got really dark as a result of tanning.
Otako comments that since Galko's skin has tanned so much, her nipples must be dark as well. Along with Ojou, Otako yells that Galko has dark nipples.
Now, that's totally a lie.
هذه كذبة جلياً
Das ist eine Lüge!
Eso no puede ser.
T’abuses, là,
c’est grillé que tu mens.
Andiamo, è una bugia bella e buona.
Até parece, é mentira.
