Rokka -Braves of the Six Flowers-

The story is set in Rosewood Academy, a school that trains future heroes destined to protect mankind. The school accepts only those with the most potential. Arnest Flaming, a girl who boasts the top record in the academy, is assigned to guide a mysterious but cheerful new student named Blade who rivals her own power.

When a classroom of students is transported to another world to act as its saviors, Hajime Nagumo finds himself the weakest link. As his friends and classmates are granted strong classes and impressive abilities due to their existing skills, he is given the weak title of Synergist. When a dungeon quest leaves him separated from his group, Hajime must discover his own talents or be left to rot in this world forever.

Hero defeats bad guy. Good triumphs over evil. The end. Or, at least that's how it usually goes. But what happens after the hero goes home? Our hero, Akatsuki Ousawa, is about to find out that sometimes the greatest adventure starts once happily ever after ends.

The world is divided into two factions: humans and monsters called katawara. Despite being a katawara, Tama loves humans and vows to protect them from evil, even if it means fighting her own kind. Her brother Jinka, however, hates humans, despite mostly being one. The siblings are joined by a cowardly swordsman named Shinsuke, who wants to learn how to become strong. When the group uncovers a plot to experiment on humans and transform them into monsters, they vow to defeat whoever is behind it... Even if it means battling an entire army of warriors.
