A man with the power of resurrection. 31 years old / 173cm A job seeker who returns home after failing yet another interview, only to be killed by mysterious men. He resurrects 72 hours (3 days) later and discovers his ability. Every time he dies and comes back to life, his hair turns redder and his strength increases, eventually reaching a level where he can send opponents flying with a single punch. He is surprisingly positive, sly, and cheerful. He has a short fuse and can't hold back his temper in unfair situations or in front of rude interviewers. He cherishes his younger sister dearly. He is being pursued by a mysterious group. He wasn't that strong at first, but his power keeps growing (initially he just knows how to fight a bit, but later he can crush a handgun with his bare hands). He lives in an old villa apartment.

The younger sister of the man with resurrection powers. 19 years old / 164cm She cheers for her brother's employment more than anyone else and trusts him no matter what. She possesses excellent computer skills and is a smart, reliable sister who actively helps Seok-hwan with research despite his repeated interview failures. On the surface, she treats him like he's pathetic and foolish, but deep down, she trusts her brother the most.

The man chasing the resurrected man. Mid-30s / 187cm Fluent in three languages, including English and Japanese. He possesses the transcendent ability to control others at will, but his power is uniquely ineffective against Seok-hwan, who resurrects every 72 hours. Consequently, he pursues him relentlessly. He will use any means necessary to capture Seok-hwan. Consider him the final boss (extremely powerful).

The best friend of the resurrected man. Early 30s / 178cm Seok-hwan's irreplaceable friend and a capable professional in the corporate world. He is a loyalist who doesn't hesitate to give Seok-hwan harsh reality checks, yet is the first to step up when Seok-hwan is in danger. One day, he discovers that Seok-hwan, who had been out of contact for three days, has the power of resurrection. He is the only best friend who gives blunt criticism and realistic advice to the perpetually unemployed Seok-hwan. Unlike the superpowered individuals, he is a realistic office worker living a fierce daily life.
