She displays robotic behavior, kinda like Nemu, despite not being abused or anything. That, and the "Slaughter Mode" coded into her. And it's raw power, being capable of kicking around an Arrancar's posterior.
And, on top of that, Kurotsuchi Mayuri stating what his Konpaku being superior to Urahara's, meaning what Kisuke did develop them at some point at time.
My suggestion, to be blunt, is simple: Ururu is a Konpaku, just like Nemu.
She has built-in abilities, programmed behavior, and even sophisticated artificial features, like "modes". So, there is gotta be a change in her Wiki Profile.
P.S.: Also heard news about her bio in "Bleach: Can't Fear Your Own World" novel stating what she's ain't no human. Wiki Page Change is due.
