Raidorl Seiken Senki

Raidor, the second prince of the Kingdom of Zain, possesses Dahinslave, one of the twelve holy swords known as the "cursed holy sword." His older brother, Prince Granard, views him as a threat and exiles him to a distant land. After enduring hardship and battling demons, Raidor is summoned back to the capital when Granard seeks his aid against an invasion. Though outwardly compliant, Raidor is resentful and plans to rebel. As others who wield the holy swords and betraying nobles emerge, Raidor must navigate these challenges to carry out his revenge.
