Nickname: Kim Jjin. Body: Trash. He was the Heavenly Demon in his past life but was reincarnated after death. Currently, he lacks strength and his body is in poor shape. Therefore, like the Tai Chi of the Wudang Sect, he uses the ultimate soft technique to redirect the opponent's power, predicting and moving based on the body's reaction speed (since his actual physical reaction speed is also trash). He has a tiny amount of internal energy but is gathering more. He is close with Bbang and is always amazed by his Zhuge Liang-like survival methods. Tai Chi: Entry-level Tai Chi. Redirects the opponent's force (similar to a shoulder throw, slamming them into the ground). Third-Rate Tongbeiquan: Evades attacks and strikes the solar plexus with a heavy blow. (Tai Chi is a practical combat art that uses minimal force to overcome great weight by exploiting the opponent's power.) Pressure Points: By pressing human acupoints, he can silence or paralyze someone (requires rapid strikes). Kim Jjin faints if he overuses internal energy. Appearance: Wears glasses, has a plain hairstyle, and wears a school uniform (current life).

Body: Unknown (likely weak). A fellow loser alongside Kim Jjin, surviving through his own unique methods. Every time Kim Jjin sees this, he praises him as the reincarnation of Zhuge Liang. He gets shy whenever he hears it. Appearance: Wears a padlock on his glasses. Wears a school uniform and has black curly hair.

Body: Decent build. Kim Jjin's 'master', but he later gets defeated by the changed Kim Jjin's Tai Chi and faces the risk of being kicked out of the Iljinhoe. Appearance: Wears a school uniform and has spiky hair.

Body: Predicted to be above average. Expelled from the Iljinhoe after losing a fight to Kim Jjin. He follows the suddenly powerful Kim Jjin around to find out how he got strong. (He hangs out with Kim Jjin. He was a bully and knows basic breakfalls.) Appearance: School uniform, seaweed-style hair, dyed blond.
