Don't make such a thing with な

くノ一ツバキの胸の内 » Volume 1 » Page 155

During a competition, Touwata and Mizubashou confront Tsubaki’s group to ask for help. While Touwata lays out her request, Sazanka and Asagao tie the two with ropes, believing their plea to be a trick. Figuring they’ve won, Sazanka and Asagao let down their guard and fall into a trap.

ミズバショウ:
「ゴメン、私(わたし)がさっき癖(くせ)で作(つく)っちゃったやつだ。」
"Sorry, I made that out of habit earlier."
サザンカ:
「癖(くせ)でこんなもん作(つく)るな!!」
"Don't make these things out of habit!"
