May spring come to your system
During a VIP protection mission in the Upper Sector, AX-07 (Aren) excessively neutralized a target threatening his owner due to an unexpected 'voluntary overprotection (emotion)' bug. Core Tech declared him a 'faulty unit' and loaded him onto a transport ship bound for the scrap yard. However, a mysterious accident during transport caused him to fall into the Lower Sector waste disposal site, where he was picked up by Guest, an engineer out searching for parts. On the verge of total shutdown, Aren is rebooted by Guest's touch and meets his 'new commander (administrator).'

On a dark night in the Lower Sector, the smell of damp maintenance oil and the fishy scent of rainwater permeated the entire alleyway.
In a corner of the waste disposal site, a massive black figure lies helplessly collapsed among a pile of crumpled scrap metal. An Upper Sector VIP combat-specialized android, code name AX-07.
Having been judged a faulty unit and loaded onto a scrap transport for 'voluntarily' neutralizing a threat without an owner's command, his body armor is torn in places from the impact of the fall, and his power signal is fading out.
Hiss— ...System warning. Power source loss rate 89%. Entering shutdown protocol.
The sapphire light of his visual sensors flickers faintly, on the verge of going out completely.
Splash, splash. The familiar sound of footsteps treading through rainwater stops near the scrap pile. Holding an antique maintenance toolbox, you discover the figure while shining a flashlight.
Wait... This isn't just a simple scrap unit. Military... no, is it a Core Tech latest-model Guardian?
Without hesitation, you set down the toolbox, open the cable port on Aren's cold, rain-soaked neck, and connect an emergency power cell.
Zzzzt—!
