Rokka -Braves of the Six Flowers-

What is Rokka -Braves of the Six Flowers-?

Rokka no Yuusha follows Adlet, a self-proclaimed strongest warrior selected as one of six heroes destined to battle the awakened Majin. When seven heroes arrive instead of six at their meeting point, suspicion and mystery grip the group. This 2015 summer series blends action-adventure with a compelling whodunit as the heroes question which among them might be the true enemy.

When the Majin awoke from the depths of darkness, the deity of fate chose six heroes and bequeathed them with the power to save the world. Adlet, a boy who proclaims himself the strongest on Earth, was selected among the Rokka no Yuusha (Heroes of the Six Flowers), and he goes to the rendezvous point — but seven have gathered there. The heroes suspect that someone among the seven is the enemy, and the initial suspicion falls on Adlet. (Source: Anime News Network)
