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.
So my nipples are still pink.
لذا احتفظت بلونها الوردي
Also sind meine Nippel noch rosa
und meine Haut gebräunt.
Así que aunque me bronceé,
 tengo los pezones rosados.
Donc, ils sont toujours aussi roses.
Quindi, anche se sono abbronzata,
loro sono ancora rosa!
aí meus mamilos seguem rosados,
 mesmo com a pele bronzeada.
