Itsuo: Bound by the shadow

In a world where the humans have to co-exist with the devils in constant battle, a mysterious young swordsman named Itsuo awakens with no clear path, no money, and a secret sealed within him.  Sixteen-year-old Itsuo grew up in the Stone Valley of the Moonstone Kingdom. He thought he was just a normal human with a bit of bad luck. But his world is turned upside down when he is dragged into the chaotic Ryu Guild—a group of mages who don't understand the concept of boundaries. His new life quickly becomes full of intense training, and falling into absurd situations—like being forced into dishwashing by a food stall owner, after his teammates casually abandoned him to chase an old friend, leaving him with no coins. But the laughter soon ends when the guild gets attacked by a high-ranking devil, and he gets taken away. Every day, Itsuo learns more and more about this corrupt world he lives in. He makes a dangerous vow. He will tear down the corrupt system, uncover the ultimate weapon, and conquer all six kingdoms in his own way.
