Notes:
What would be the meaning of a small-framed humanoid guard bot? If cyborg or mecha criminals would storm the building (for any reason), it wouldn't have a chance, with that baton as its only weapon ...

They could set up a guard mech or automatic turrets, but it wouldn't be such a habitable environment, would it? Hence the old, cozy bot ^_^

The girls' door is locked with a fingerprint lock. With maximum security enabled, the door has also key, voiceprint and retinal scan locks, but as they probably thought they'd only be out for a little while, they took it simple...
