Brenda

Brenda lives in the western part of Holic City. Like other blind people, Human Services Center removed her eyeball when she born. Luckily, her family has good trade with Coretown, and the Machine Chamber of Commerce has mercifully assigned a retired civilian D-model working machine dog as a usual help and security tool.  

Her friend secretly made her a blind-friendly locator umbrella in violation of protocol. The umbrella_s handle has an environmental scanning instrument that can quickly read the surrounding geography and then reconstruct part of the reality scene in her brain through a pulsating artificial ear connected to the back of her head. This allows Brenda to live more easily without having to rely entirely on D4612.
