A native of Preton Eika has a deep fondness for her hometown and distrusts PUS, which abandoned it in a disaster known as sunset or 落日. Her parents operate a family-owned restaurant, where Eika helps out as a delivery worker.

In her free time, Eika works part-time, practices the guitar, and is a part of a band.

A duelist from The Scissors faction, this masked Superstring guards the streets of Preton with flames.

Eika wields a shotgun and is therefore effective only at close ranges. Her kit is also designed for close quarter combat in tight spaces, such as an indoor hallway.
