Kyoko started out as a clone of
kyonko_narrates with orders from Baron Archibald Von Strauss to capture
sossanity and eventually take over his body. His reasoning was a male body would be superior--hence why Kyonko was targeted for kidnapping first instead of him--and that Kyoko would want to live longer than two months. Kyoko didn't understand the logic of this seeing as how she liked being a girl just fine and two months seemed a million years away to her, being only a couple days old at the time this went down. She went along with this to see where it went, but ultimately turned against Archibald when it was time to swap souls with Kyon.
Because Kyon looked funny when she made passes at him and Archie was just such a cliche villain that going with CO seemed like a better idea.
She then went on to help the rest of CO thwart off [Humanity]'s invasion, treating the whole thing like a game and not feeling nervous until Aenathia--powered up by the captured
havefunwiththem was right at the Mainframe's Gates and could potentially slaughter everyone in there whole. Fortunately they won, and Kyoko's belief that CO was really fun and awesome was cemented. Not to mention there were tons of cute boys to flirt with and people to mess with. Kyoko was on board with this!
Eventually she flirted with
icecreamai who went into "fan appreciation mode" and, upon hearing she was supposed to die soon as a natural state of her being a [Humanity]-made clone, decided to look into getting her transferred to another body. Kyoko didn't really care one way or another until she had a conversation with Kyon that made her realize people would care if she was gone and that she wouldn't be able to see and do everything she wanted to if she only, by then, had a month and a half left. So she went with Kaito when he managed to talk his 'Master' into transferring her mind into one similar to his minus the USB port. This took a week to complete, plus some physical and occupational therapy to get used to her new body. Once that was done she decided to become a proper agent at CO and has been enjoying herself ever since.
For all intents and purposes Kyoko is now a normal human girl. Her brain just happens to be a CPU in her head since Kaito's world hasn't yet reached the tech level possible for a completely organic transfer. Kyoko herself was the first human to be transferred and there was a good chance it wouldn't have succeeded in the first place. Her current body bears little to no resemblance to Kyonko, aside from her choice in hairstyle and having a similar general build to her.
