Is Tobi dragging her briefcase because she is too short to straighten her arms without it touching the ground?

Given that she would have to raise her arms up to her head to get it off the ground... yes.

Aw man, why are you tired?

Rest up Neorice :(

My sympathies, these are draining times. I hope you're able to get some rest.

Hope it's nothing bad and you'll be fit soon

The other team's sending Levin first, aren't they?
