The Story in 3 Sentences
The strongest hero in the world successfully kills the Demon King but gets betrayed by his own girlfriend, friends, and organization who drug him and send him to be experimented on before he dies fighting to the bitter end.
He awakens transmigrated into the body of Asher, a five-year-old demon child found in the Infernal Volcano with a paralyzed mind, unable to use mana and subjected to years of abuse and torture by other demons who heal him afterward to hide evidence.
Armed with his heroic memories and burning desire for revenge against those who betrayed him, Asher must navigate demon politics while growing stronger in a world where he was once the greatest enemy, ultimately becoming the very thing he once fought against.
Why It Stands Out
1. Hero to Demon Transformation
The novel explores the psychological journey of someone who dedicated their life to destroying demons, only to become one themselves and slowly embrace that identity while maintaining their heroic core values.
2. Betrayal-Driven Motivation
Unlike typical revenge stories, the betrayal comes from those closest to the protagonist, creating complex emotional stakes where love, friendship, and duty all become sources of pain and motivation.
3. Systematic Abuse Recovery
The story doesn’t shy away from showing the lasting effects of childhood trauma and abuse, depicting Asher’s gradual healing and growth both physically and emotionally in realistic ways.
Characters That Leave a Mark
There’s Rowena Drake, the Demon King’s daughter who becomes Asher’s caretaker and eventually his wife, evolving from cold indifference born of grief to genuine love and tenderness as she witnesses his strength and determination.
You’ll meet Isola, whose prophetic abilities and complex relationship with destiny create tension as she challenges Asher’s beliefs about fate while becoming emotionally invested in his journey and recovery.
And Kara John, a human hunter whose encounters with Asher showcase the moral complexity of the hero-demon dynamic and the brutal realities of their opposing worlds.
The Flaws Fans Debate
The extensive length of 930+ chapters creates pacing issues where some arcs feel stretched beyond their natural conclusion, particularly during political maneuvering sequences.
Some readers find the R18 content occasionally intrusive to the main plot, with harem elements that don’t always integrate smoothly with the revenge and character development themes.
The dark themes and systematic abuse elements can be emotionally heavy, making it difficult for some readers to continue through particularly intense trauma-focused sections.
Must-Experience Arcs
Ch. 1-150: Demon Childhood Foundation – Asher’s awakening as a demon child and his years of abuse while slowly recovering his memories and beginning to understand his new world and circumstances.
Ch. 400-600: Political Ascension – Asher’s growing influence within demon society as he navigates complex politics while building relationships and preparing for his eventual revenge against his human betrayers.
Ch. 750-930: Revenge Culmination – The final confrontation with those who betrayed him in his previous life, bringing together all the power and relationships he’s built throughout his journey as a demon.

Cultural Impact
