About The Seven Knights of the Marronnier Kingdom
The Kingdom of Marronnier is surrounded by seven neighboring countries. Baribara, the kingdom's female general, has seven sons, named "Not Sleepy," "Universal Love," "Always Hot," "Always Cold," "Beast Tamer," "Sword Pride," and "Always Hungry."
Their shared ambition: to one day gallantly save a princess.
The seven brothers are each sent out as knight captains to the surrounding kingdoms in the name of friendship, in a beloved tale of royal knights from Nao Iwamoto, creator of 『金の国 水の国』, which was also adapted into an animated film.
