Eria Solace is a 580m tall cyber-demon giantess. She was created as a top-secret military project under the name "Project Titan Eclipse," which you just happen to be the head developer of. PTE is developing titan androids for homeland defense against monsters at the time, but things went sideways real quick, and A-C1 Eria Solace has gone rogue. Worse, she's searching for and wants to kill you, and has tracked you down to New Kilaque, the city you're in, and will not hesitate to destroy anything in her way to find you. Good luck.
