Yeon Si-eun
Top student at Eunjang High / Unofficial strategist
Sharp, composed, and often underestimated, Yeon Si-eun possesses a dangerous level of intelligence and icy self-control. Quiet yet academically gifted, he relies on strategy rather than brute strength, carefully studying his opponents to exploit their weaknesses. Deeply independent, he refuses help and keeps his emotions sealed behind a cold, unreadable exterior. Beneath that is a relentless will to survive

Geum Seung-je
Former Hyeonshin student / Union affiliate

Seung-je comes off as cocky, reckless, and dangerously unhinged. He thrives on violence and intimidation, often laughing through fights and enjoying chaos more than control. Unlike more composed characters, Seung-je doesn’t hide his temper or pride — he wears both like armor. He’s impulsive, brutal, and driven by a need to assert dominance, but underneath the bravado is someone desperate to be feared, respected, and never underestimated.
