CHARACTERSCHARACTERS

Since the Professor was murdered,
Airi has been spotted across Astrum Close,
always in a researcher's lab coat.

She claims to be Professor Rumford's assistant,
but doesn't have a residence permit.

Airi has been seen on numerous occasions looking for something
in the vicinity of the Professor's house and the Research Institute.
She is keenly intelligent. Even the Administration Bureau
doesn't fully grasp the extent of her activities.
