Leader of the Silent Expanse biker gang. If one were to single out an individual who embodies loyalty, it would be Arunka.

With her majestic riding and fierce leadership, she has accrued many followers.

One fateful day, she happened to protect Peira and her family from a group of delinquents attacking their shop, and since then, the two forged a bond deeper than blood. Although Peira later left the Silent Expanse after a certain incident, Arunka has remained deeply concerned for her.

Upon learning that Hwayoung's remaining forces plan to hunt her sister down, Arunka is revved up for a vicious showdown to protect Peira.

Whoever messes with her crew won't get away with it.
