Love how Koa is the only one vaguely surprised. Also Remi and a spork lol.

Poor table manner

Flandre: "A fight to the death sister! Now!"

Remilia: "Can't this wait until after I eat?"

Patchouli: *sips wine*

Sakuya: *cutting steak*

Meiling: *mouth full*

Koakuma: "Isn't... anyone going to stop this?"

This must be when a recently summoned Koakuma was still getting used to Flandre's antics.
