Height 180 cm One of Castle's greatest cleaners, their epithet for professional killers, Tae-Jin is a man of contradiction. One of their best assassins, yet he despises killing; a criminal who has committed atrocities in life and serves monsters, yet is a religious person who attempts to atone every day. Tae-Jin kills because that is what he is good at and the only way he sees himself able to change the world, but has grown jaded and lost, donating much of what he gains to charities and churces to atone for his deeds.
