Perhaps because Faynoc is a pedo in the same way that he displayed his attraction to the picture of Myrie Ricewood? He seems to target those who are either unable to defend themselves, totally naive, or have a "life debt" to him.

Also, the fact that it means that he was tinkering with her body to change her age and thus how she looked. That might make a significant difference in the future.
Let's pretend that Myrie was already kidnapped and tinkered with. (Damn you to hell Faynoc) If given the order to rescue her, PATCA would probably be given a photograph or some sort of visual representative so as to identify her. However, if she was tinkered with, the group might not recognize her as the person they are supposed to help since the photograph would be "out of date", and might end up fighting her (if she was brainwashed) and at worst killing her. Which would be a tragedy.

This might also come into play if the tinkering was also used to evade detection/capture. Could you imagine if Burkmont got a hold of this thing and could change his appearance so charges against him couldn't stick because he'd disappear whenever he could and assume a new identity, probably wait a little before causing havoc?

Now that I think about it, this might be a result of Faynoc tinkering with Ditto DNA for all I know. ^^:

On the other hand, it does mean that none of the PCs can seriously think of having a Love-Tech with Mio without being a pedo-perv, unless it was a strictly platonic love. Not that I think anyone would seriously consider using the limited Love-Tech slots on her when we have so many other ladies. :3
