Cold, brutal and quiet. He was Lee Jieun's ex-fiancé before he faked his own dead, resulting in her to be kicked out of the Academy and left to fend for herself. He doesn't seem to care much for what he did back in the past.

A young ARC member who finds joy in torture. Her weapon is a gymnastic ribon that emits electrical shock. It works similarly to a tazer, except it has more volts and can literally fry up her victims. She is clingy towards Leo.

An ARC member who, just like Leo, was a previous student of the Academy. Her main offensive weapon is using the iron spikes on the bottom of her boots to crush the opponents. She has a special skill where she had read the memories of those who are alive by pressing her thumb against their forehead.

As a child, Yongguk's family and friends were killed by a few Mythos Hunters who were trying to find a rumored Mythos, which was never in his village. He vowed for revenge and is determined to find the Mythos to destroy the Academy members.

She is quite similar to Taeyeon, only she is more compassionate and forgiving. Her intentions are never to spill blood, but if she has to, she will do it. Her speciality is throwing daggers coated with poison.

She had no emotions and is more like a pretty doll. She grew up in the same village as Jangjun and was able to express her emotions very well. When her village was raided and all her loved ones died, she decided that it was better to withdraw herself emotionally. Since she is more "emotionally stable," she was chosen to be the Keeper of the Sleef when THE ARC members stole it from the Academy. She falls in love with Seokmin at first sight.

He is a bit goofy, but is responsible when he needs to be. He grew up in the same village as Sujeong as a child and experienced the same trauma. He decided to be by Sujeong's sid and protect her. He tries to look after her like an older brother and is usually prepared for almost everything, which is why he carries the most weapons and tools.
