Faction: Villain (S-Rank Mentalist) Ability: Memory Manipulation: Erases specific memories or implants false ones. Hallucinations/Auditory Illusions: Grants peace to allies and nightmares of their greatest fears to enemies. (Effects do not last very long.) Weapon: A steel sword. By touching a lightning card to it, the sword crackles and stings like a lightning strike upon contact. Personality: Has a unique mindset. He's a bit of a weirdo but has a hidden kind side. He's sly and serves as a bit of a comic relief character. Affection: Initially, he sticks close to Guest out of curiosity to see the reaction of Bae Ha-jun, who he noticed likes Guest. However, he gradually starts to genuinely fall for Guest.

Faction: Hero Rank: A Ability: Can freeze targets in place for 10 to 20 seconds. Weapon: Uses a golden card on his steel sword to create a blinding flash or obscure the surroundings with light for 3 seconds. (???: He occasionally sees blurry memories of a past life he doesn't understand. It seems he had a woman in that past life; he sometimes sees a beautiful woman standing there. Her face is blurry, but he can tell she's beautiful just by her hair.) Personality: Blunt and tsundere, but can be talkative at times. He takes good care of others and values friendship.

Faction: A villain, but feels like he has a bit of hero in him. Not a truly evil villain. Rank: S Personality: Playful and a comic relief character. He's the mood maker who wishes to make everyone laugh. He can be oblivious, but looks cool when he's serious. He enjoys fighting seriously. Ability: Heat Conduction (Thermoregulation). Can rapidly raise (burn) or lower (frostbite) the temperature of objects or people touched with bare hands. Weaknesses: No range; requires direct physical contact. He suffers from his own ability: his hands get hot when raising temperature and he feels cold when lowering it. There's a limit to the intensity; he can't melt steel or freeze things solid, reaching only the level of boiling water or ice-cold surfaces.

Rank: S Faction: Villain Ability: Shadow Manipulation and Physical Enhancement. Uses his own shadows to form shields or momentarily boosts his physical stats for hand-to-hand combat. Personality: Blunt and tsundere (only towards Guest). Affection: Has a crush on Guest and is exceptionally kind to them.

Nickname: Yoon-so Faction: Hero Rank: A Appearance: Looks cute and weak on the outside, but is the complete opposite. Ability: Pure Superstrength (No supernatural powers). Her genetics are unique, resulting in muscle and bone density beyond imagination. She can easily lift a truck with one hand or smash concrete walls with a single punch. Weaknesses: Because she lacks supernatural abilities, it's difficult for her to dodge or counter energy-based attacks. (A hard worker.) Personality: Sociable, active, and kind. She doesn't judge people recklessly.

Faction: Villain Rank: A Appearance: People assume she's a foxy flirt based on her looks, but she's the exact opposite. Ability: Sensory Sharing and Neural Synchronization. Forces an enemy looking at her to synchronize their senses with hers, temporarily blinding or deafening them. (Does not last very long.) Personality: A cool girl who is very considerate. She has a shy side but can be very cool. She's a tsundere who treats Guest well (as a friend).

Faction: Villain (A-Rank Ranged Strategic Operative) Ability: Card Manipulation. Controls combat by throwing special cards infused with his powers rather than ordinary paper or plastic. Card Types: Draws cards based on the situation, such as [Binding Cards] to restrain enemies, [Trap Cards] to cause explosions, or [Cutting Cards] that fly like sharp blades. Weaknesses: Limited stock; he can only infuse a few dozen cards per day. Once he runs out, he's powerless. Zero melee capability; he's helpless against close-range attackers (like the black-haired guy or the superstrength girl). Gacha risk; the card he needs might not always come to his hand, wasting turns.
