Si Mun Lee is the main protagonist of SID, and an exorcist currently working with Tenka Hennigquald, Baram Kang, and Sophia Kang in the Supernatural Investigation Department of the FBI.
When Si Mun was a boy, his grandmother was a famous shaman. She gave him a pouch that he was only to open if he began seeing spirits again.
After meeting Tenka, the two engaged in a fight with Ga Yeun Chae's spirit, and Si Mun opened the pouch, that gave him supernatural abilities to protect himself and fend off spirits. He soon met Baram Kang, and the three together joined Sophia's new Supernatural Investigation Department in order to prevent the new Somos478 cases from happening.
His default demeanor is rather serious. This rings true for both his professional and personal lives, which admittedly overlap. He is respectful to his coworkers and his superiors, but is also willing to push boundaries and ask the hard questions if needed.
Si Mun's power is to be able to generate electricity
