Biography

Service under Yoo Yeonha

Jin Sechan first appears as Yoo Yeonha's composed attendant, delivering the suitcase containing Kim Hajin's new handgun and handling his employer's business without drawing attention to himself. Years later he remains at Yeonha's side as a secretary trusted with sensitive reports, transport, and arrangements. That trust puts him in danger during the Pandemonium operation and carries him through the Demon Realm Gate, where he continues supporting Yeonha after the group is stranded in Leores. Once Shimurin returns them to Earth, he resumes representing Essential Pharmacy and helps pursue the elusive pharmacist whose work could aid the company. (Chapters 17, 274, 304–309, 317, 366, 370, 372, 377)
