In episode 2, there's a scene with Utsu-tsu cleaning the Tachikawa City International Greenery Garden where she volunteers. However, the scene is a bit strange, as it shows two of her in the same shot:
As far as I can tell, both of the people in the shot are Utsu-tsu. She's also in the two shots before this one, and doesn't seem to move between them, so there could be more than two of her.
Why are there two Utsu-tsus here? Is she able to double her body, or does she have clones, or are they imposters, or something else?
