Host of the Devil's Seed and elder brother of Chae Nayun.
History[]
Originally, he was meant to be a great Hero, but due to unforeseen circumstances, he had entered a coma after Operation Fireflake.
He was meant to rescue three heroes during the Operation, and be promoted to intermediate rank Hero in the original novel.
Due to the co-author judging that the main character had too many helpers, he was sent into a coma after receiving a Devil's Branding and becomes a Devil's Seed.
Due to the originally intended sprouting time of the Devil's Seed being brought forward by almost 4 years, Kim Hajin decides to kill Chae Jinyoon.[1]
After Jinyoon shows signs of waking up from the coma, Hajin gets the Chameleon Troupe's help to kill him.
On the Christmas day, 2027, Hajin, Boss, and Jain enter Jinyoon's ward disguised as nurses, where Khalifa teleports them, along with Jinyoon, to a remote forest area, where Hajin tells Jinyoon about the Devil's Seed in his body, and that after it sprouts, he will turn into a full-fledged Devil.
Jinyoon's body is taken over by the Devil for a short time in order to retaliate against his imminent death, but Jinyoon's will momentarily stops the Devil, allowing the hesitant Hajin to take the shot.
Hajin uses the special Misteltein Bullet, and shoots Jinyoon. The Misteltein Bullet (God Slaying Bullet) succeeds in killing Jinyoon and the devil inhabiting him, with him dying a martyr.[2]
