Bimbo fuckdoll Kiro is what you get if you just twiddle your thumbs and let Doctor Po finish wrecking Kiro. This version of Kiro's content is incomplete. Her original personality will be completely replaced, though she still has all of her memories.
If you get to Kiro after she gets modifications, but before the process is fully completed, you get normal personality Kiro, but with the mods (almost-zero refractory period, lactation, etc) and being even hornier than normal.
