Come to think of it. Some time ago i asked about the possibility of Unison Devices having a "mechanical" nature, having internal pieces or something because they're trated as the same as Raising Heart and Co. and Shari takes care of them instead of a doctor, etc... At the end my question is answered and we agreed to handwave the situation as Unison Devices being closer to familiars and thus being legitimely living mangical beings.

...if that's true. Then what about Lily? She's a reactor for a powerfull Anti-Magic source based on non-magical powers thus the "magical living being" handwave is less plausible here. Still she acts pretty much like a living being and is also a carrier/spreader of a powerfull virus which makes dubious she's a robot girl or something. Then again, the virus and her control over it pretty much works like a series of programmed commands with keys and passwords, like a more artificial and computarized version of an unison device(complete with "analizer screen" sight effect).
