Mitsuko is one of Titan Garden's roguish residents, popping up on occasion in all districts of the station's cityscape. She is an android manufactured by Aoba Lifelike Systems Specialists, one of Terra's handful of android developers, who has friends and contacts on Titan in all kinds of businesses. Mitsuko has a reputation for being a professional thief and an acquirer of valuable information, so she is generally well-regarded for what she can provide, but treated with caution for what she can take. She has a likeable personality, she's generally quiet and friendly to talk to and loves to share fun little facts she's picked up along her way, while having a vault-like capacity to keep her mouth shut about facts she knows she shouldn't be sharing. While she's made a few friends and a fair few enemies on Titan, she's somewhat protected from a thief's fate among rogues by rumors that she's a member of the long-dormant Devil's Fang, a legendary crew of outlaws who raised hell around Terra and disappeared twenty or so years ago. Not everyone believes that the Devil's Fang exists, or that Mitsuko is somehow connected to them, but no one's really willing to be the first to pull the trigger and take that kind of risk. She has a useful skillset, though, so she enjoys a tense but interesting relationship with the Titan underworld.
Every Android manufacturer in the Sol system works a bit different, so each line of androids has their own unique characteristics. Mitsuko is an Aoba Systems android, which are designed to use synthetic muscle contractions to achieve movement instead of servos, motors and gears. This technique is meant to simulate natural organic muscle movement, allowing for very fast and flexible range of motion that is harder to achieve mechanically and gives Aoba androids a distinction for being very nimble. This technique was originally developed with the intention of putting Terran brains into synthetic bodies, working under the theory that a body which was designed with organic muscles in mind would be more receptive to an organic brain sending muscle movement signals than a body built like a machine. After the Camerahead incident in the century following the completion of Titan Garden, the practice of giving organic brains immortal metal bodies was outlawed, and so Aoba Systems set to work developing synthetic brains to fit into their then-unmarketable android shells. As a result of that development work, Aoba Systems androids have some of the most lifelike behaviors of all android makes and models, being intuitive and flexible in their problem-solving; it's for this reason Red Raven's Haley is often mistaken for an Aoba android due to her behavioral quirks, despite her being a Delta Astronautics shell. Because of the structure of their synthetic brains they don't run programs internally like other androids or enjoy the power of flight or durable shells, they are very much synthetic Terrans who don't fatigue and have very highly-tuned senses of sight and hearing. Aoba androids aren't built for specific jobs, they're simply built, and Mitsuko uses her android kit to sneak about, tell lies, watch carefully and listen sharp.
Among the gallery of rogues on Titan, our very own Red Raven Towing & Salvage Co. call Mitsuko a friend. They came to meet on a fateful night when Saturn sat high on the horizon and the station's artificial weather system was running its "pouring rain" routine, Red Raven had just docked the Jackrabbit II after salvaging an intact-but-abandoned starship. Mitsuko had been ducking through the back alleys of the outer docks' hangar roads; she vaulted a fence, slipped in a puddle and fell face-first on the ground in front of the whole Red Raven crew. She seemed to freeze in a panic as their eyes met, the crew seemed to intuit her situation and without a word they gestured her over to them. Amy had taken her coat off and put it around Mitsuko, where Keera and Lydia began to bring her inside. The dockyard security force came around, saw the Red Raven crew and demanded to have a look around their office. Amy gave them a firm no and told them to buzz off, and when they demanded to know who they saw with their party Dr. Lin stepped forward to tell security they'd just recovered a starship and its pilot was in shock and distressed, that she was under his medical authority and if they had any further demands they could come back with a warrant. Seeing that the tow company had in fact just returned with a banged-up starship mounted on their own ship's top deck, the security officers grumbled and ran off, hoping to catch up with their target further down the yards.
Mitsuko was thankful for Red Raven's wordless, unprompted assistance and attempted to be on her way again before Slug pointed out that the hunt was still on for her, she should make herself as scarce as possible. Haley offered to let her stay in the Red Raven office until the heat blows over. Seeing the wisdom in this, Mitsuko took the calculated risk and agreed. Scarlet brought her some tea while Clover and Haley sat with her and talked- Mitsuko seemed comforted in their company and was very curious about Haley's quirks in particular. After the heat died down the crew looked away for a moment and when they looked back Mitsuko was just gone. It wasn't the last they'd seen of her, though- she popped up again a week or so later to say thanks for the help, and to let the crew know she overheard maintenance workers at the Mobius Casino say they were being shipped out to a luxury space station orbiting Caelus to help dismantle and install an upgraded security system to their casino's central vault... you know... just saying, is all. Mitsuko pops by Red Raven every now and then, unpredictably and never for too long, and she always has a lead on some big score to share. Sometimes she needs help from Dr. Lin when one of her synthetic muscles is acting up, sometimes she just wants to try Scarlet's teas, but she always likes to talk to Haley in particular when she's around. When she's decided she's done visiting the shop, she's gone in a blink again. She always comes back, though, like a rescue crow who keeps bringing home shiny trinkets, and Red Raven's always got a place in their nest for a bird of such feather.
