Please explain what's going on, then. Some of us can't read kanji.

me too.

they're exercising from the look of it

Eirin has never been so glad for Mokou to take Kaguya out.

She's tired already? Bet they haven't been at it for 5 minutes yet.

Death by jogging.
'S up there with being hung drawn and quartered and water torture, isn't it?

I'm not entirely sure, but I presume the scenario was:
Kaguya was in her normal NEET uniform (a tracksuit).
Mokou discovers her, and asks why's she's dressed so.
Kaguya, being a prideful princess, says she was going jogging.
Mokou accepts it, and then pic related.
