Setsuna is a charming, attractive professional killer who balances her deadly work with married life at home. When she is not out killing people, she is trying to settle into a domestic routine with her husband. Her efforts at being a wife come with an unusual edge: she sticks elements into dinner and draws a knife on unwanted visitors. Meanwhile, her lovestruck husband asks few questions about her everyday occupation, and the two carry on together.
