Haru has an excellent sense of taste and surpassing skill in the kitchen, but she has been divorced from her first husband after only a year of marriage because of her impetuous character.
One day, Haru is proposed by Dennai Funaki, samurai chef from Kaga, to marry his succeeding son. The Funaki family who has served the Lord of Kaga not with the “sword” but with the “kitchen-knife” is well known as “Kitchen Samurai” for generations.
However, now, her new husband Yasunobu wields a kitchen-knife with no skill at all. In order to save the family name Funaki and its position as kitchen samurai, Haru decides to teach him the art of cuisine...
The story is inspired by a real-life family in Kaga that has survived countless upheavals with its cuisine.
