Ep. 2: Rio reacts with shock as Ayano falls asleep under her kotatsu after removing her socks.

2

The command room receives a report that a Fiarem has been spotted. In response, Rio orders the observer to contact Ayano. It then cuts to Ayano, who is half-asleep underneath her kotatsu, much to Rio's shock. Her feet are outside of the kotatsu, making her cold, so she tucks her feet in, but this makes her too hot. She then precedes to remove her socks which, according to her, "feels good". The observer reports to the clearly agitated Rio that she has fallen asleep.
