Rolan, the world’s strongest swordsman, spent his days battling to defeat the Demon King. His greatest source of strength was his beloved lover, Felicia. But under the Demon King’s curse, she transformed into a monster. Felicia, having lost her sense of self, attacked Roland. In despair, Roland fought her, and the two struck each other down. As his consciousness faded, Roland heard a voice: “You must not die here…” Rolan was revived. In place of the arm he had lost in battle, he gained the arm of Felicia, now transformed into a monster. A dark fantasy begins—Roland seeks revenge with the arm of his dearest love.
