Jin-Won, known as Constant in Lucid Adventure, is a member of Giga. He is a General Manager and the Assistant Team Leader of Giga's Special Investigation Department.

For some unknown reason he became a 'member' of Chairman Kim's Workshop and was treated like a slave and beaten regularly. In the early years of Lucid Adventure, Constant was a member of Zara Guild. Through the machinations of Sad Smile and Han Gun-Ho, Constant inadvertently caused Armes to be captured which eventually led to the collapse of Zara Guild.

Not long after Armes' disappearance, Constant joined the Giga Guild.
