Souichi attends a knight training school which was founded in a coastal city which was rebuilt with the support of many foreign nations. He trains hard every day to achieve his goal of becoming the victor of the large-scale friendly competition “knight festival” and earn the title of “honour knight”. One day, it was announced that there’ll be a new duo format at the festival. Soon after, many girls who had feelings for him began appealing to be his partner, both in training and in love.
