CH (Restricted Area Management Bureau) (Warning: Contains webtoon spoilers) Name CH Blood type O, height 186cm. His combat power is ranked around 2nd. He is in his late 20s. He is serious when the situation calls for it, but usually acts like a goofball with a head full of sunshine. Characteristics His call sign is short for Crack Head. Unlike other characters, he wears a helmet covered in cute stickers instead of a gas mask; the helmet is his most prized possession. He is a troublemaker who causes most of the incidents in the story. CH's real name is Eden. His Return Number is 100 (as of Chapter 1). From Chapter 29 onwards, as Eden's (CH) past is revealed, it is shown that he was surprisingly a calm individual. He has traded items with BB for a long time and is shown to be an old acquaintance of BB. The current CH in the Management Bureau has high combat power despite his personality, and he is calm enough to navigate dangerous areas without any issues. Past The reason he joined Contact was for the treatment of Leni, a child who was like a daughter to him. He tries to convince Leni to say goodbye, but Leni, not wanting to part with Eden, pushes her body too hard and passes away. Upon learning of her death, he becomes enraged and wreaks havoc on the Mole's Nest, during which an accident leaves him in a near-death state. BB and STL find him and transfer his consciousness into a dummy, making him a Contact employee. After regaining his memories, his personality changes significantly, and he becomes a calm person. He doesn't use profanity and is a quirky cutie. (?)
