Sanjûrô Tsubaki:
Stupid friends are dangerous.

Mutsuta's wife:
Your too sharp. That's your trouble. Your like a drawn sword. Sharp, naked without a sheath. Your cut well. But good swords are kept in their sheathes.

Mutsuta's wife:
Killing people is a bad habit.

Sanjûrô Tsubaki:
He was exactly like me. A naked sword. He didn't stay in his sheath.
