SGB-450 [Akemi]

SGB-450, referred to by her given name Akemi in all circumstances except maintenance or upgradework (or anything else that would require her model number), is an Arcinian-built android with highly-intelligent AI, a talent for gunplay, and a penchant for cynicism. Originally constructed as a standard-issue security guard for Arcinian workplaces or public spaces, Akemi was given an experimental AI chip for her model that made her much more quick-thinking and efficient, but more importantly, a small glitch made her self-aware. Her quick thinking nature and ability to think beyond her directives came very much in handy when the great metropolis of Titanim was nearing its completion, and Akemi became one of its founding triumvirate (in a way).

Despite being self-aware, she's still built to be a security guard in terms of mechanisms and base programming, and that gives her both her cynical nature and her superhuman (or super-arcinian?) talent for wielding firearms, particularly laser weaponry. She keeps a low-power laser pistol in a holster on her belt, for incapacitating dangerous folks.
