Avenger of Mystical Eyes – Blood Parasite

"Will you become my family?" Archive, the weakest demon, was picked up by the Demon King when he was on the brink of death. Unable to bear children and destined to harm others if approached, Archive became the Demon King's only "family" and enjoyed happy days. However, demons hated humans, and humans hated demons, waging wars for each other's peace. To defeat the Demon King, the Eight Heroes used peace as bait to lure him out. Weakened by a trap before Archive's eyes, the Demon King suffered humiliation. Archive, powerless to help, a member of the weakest race, had his head severed and the Demon King torn apart and sealed away. As Archive's consciousness faded, if only he had the power to protect the Demon King, he exerted his final strength and cast a certain spell on one of the Eight Heroes, Lizelotte. 【Forbidden Magic to devour the soul of an unborn child and take over its existence—Incubation】 With this magic, Archive succeeded in taking over the unborn child of Lizelotte, who was already pregnant. Transformed from the weakest demon into the child of a hero, Archive possessed the 'Magic Eyes' that manifested as a sudden mutation. Petrification, fascination, fear, clairvoyance, telepathy—able to master all types of magic eyes, Archive vowed revenge against the heroes. Even if the target of revenge was his own mother, who suffered to give birth to him, or his lover who loved him despite his immaturity— "Wait, heroes—I will kill you and surely reclaim the Demon King!"
