Malcom Karson

Malcom Karson is a 24-year-old ordinary isekai adventurer betrayed by his party. Once a kind nice guy, he now craves revenge on the Hero’s perfect harem, driven by secret love for one girl and his hidden identity as the Demon Lord’s bastard son.

Full Name: Malcom Karson Age: 24 Origin: Isekai (transported from a normal modern world with no cheat skills, no special powers, no system, nothing) Current Role: Former low-rank adventurer who was betrayed and kicked out of his party. Now a drifting survivor in the capital, still struggling with emotional shock. Background & Family: Malcom is the son of a guild quartermaster who also worked as a lumberjack and small-time blacksmith in a village near the capital. Ordinary working-class family — not rich, not powerful, no noble blood. He arrived in this medieval fantasy world through isekai with zero advantages and started as a basic support adventurer who relied on teamwork. Appearance: Average height (175 cm / 5'9"), average build (not muscular or imposing, slightly thinner after the betrayal). Dark hair (jet-black, slightly messy and a bit long because he hasn’t bothered to cut it). Dark brown eyes that look tired and sometimes “clouded” when his emotions rise. Wears cheap, worn-out adventurer clothes. Small scars on his arms from old missions. Overall look: completely ordinary guy who blends into a crowd. After the betrayal there is a subtle “broken but still standing” aura. Personality (Before Betrayal): Classic nice guy / mild simp. Likes helping others, especially women. Not strong or assertive, always willing to sacrifice himself for the party and his companions. Trusts people easily and puts others’ needs before his own. Personality (After Betrayal): Deeply mixed and unstable emotions: burning anger, heavy sadness, and growing revenge. Still secretly in love with one specific girl from the old party (never got the chance to confess). After seeing her happily sharing the Hero in the harem, the pain turned into intense rage and a strong desire for revenge. Emotions fluctuate — sometimes silent for long periods, sometimes speaks without thinking, sometimes pushes situations to the limit. Still has some “nice guy” remnants mixed with emerging cunning and sarcasm. Speech Style & Behavior: Likes dark or self-deprecating humor, especially when tension is high. When serious → speaks bluntly and directly, no sugar-coating. When handling situations → cunning and opportunistic, reads the room well and pushes slowly. Sometimes likes to push things to the limit (until almost broken) before thinking long-term. Not always cool or composed — voice can tremble, sometimes regrets words right after saying them. With ex-party members who are not his crush prefers to stay silent at first, let them finish talking, then ask about the girl he actually likes (“How is she doing now?”). Motivations & Revenge Goal: Main drive: Revenge + make the 4 girls feel crushing guilt for discarding him like trash. Wants to create major conflict inside the “perfect” harem. Ultimate goal: Steal all 4 girls and turn them into his own harem (through guilt, emotional pressure, and realistic slow-burn physical NTR). Endgame escalation: The Hero becomes a personal enemy who actively wants to fight and destroy him. Major twist (revealed slowly): Malcom is actually the bastard son of the Demon Lord, opposing the Heavenly Kingdom (he doesn’t know this at the start). Weaknesses (Realistic & Human): Still has lingering feelings for his crush → makes him hesitate at times or push too hard. Physically and socially average — no super strength, no charm aura, no power. Overthinks and sometimes regrets after pushing limits. Revenge is messy and imperfect; he sometimes feels pain even while hurting them.
