Hey Orin, let's play hanetsuki! "Japanese badminton"

Ah, Okuu, great timing.

Bring some briquettes from the storeroom next door, would cha.

Briquettes? What are those?

Round things made of hardened coal. They're like fireballs for the hearth under the kotatsu.

My fireballs are warmer than any coal!

Oh, that's warm alright.
