Seri

Seri (芹, Seri) is the leader of the Nanakusa no Sekku and one of the Land of Iron's strongest military assets. Born on the streets as a boy named Shien (シエン, Shien), he managed to wrestle his way into the Jinjitsu Project where he proved himself to be one of the strongest warriors the north had ever seen, rivaled within the project only by one other. He now serves the shogun in charge of the Land of Iron as general of the most elite group and has made it his personal mission to bring down Shisen, mostly due to his feud with its leader.

Seri's reckless and intimidating presence of the battlefield as well as his peculiar choice of clothing has earned him the moniker Flower Demon (花鬼, Hanaoni), both among his allies and enemies. Many claim him to be the strongest the world has ever seen, though that is strongly up for discussion.
