HELP

From what i understand he was Cain's assistant but he was plotting against Cain all along and he's also on the demons side ( Satan's side to be exact ..... I think ) he uses the main character's ( the uke ) friend as a door which lead the dude ( the white haired guy's door ) to insanity ( i think) he also wants cain gone ..... That's what i understood so far I'm sorry if there's something inaccurate but this story is hella confusing ┐(´ー｀)┌

omg ok that’s kinda what I got too OK ANOTHER QUESTION who are those scientist people ?? The thing that Cain was looking for ?

Scientist ? ... Do you mean the doctor ?? ... Well if that's what you mean he's a doctor that's really skilled and he's the only one that can remove that thing in Cain's heart ( the thing that is making him weak and not as powerful as he's supposed to ) so Cain was looking for him and told the white haired dude to look for him but the white haired dude ( who doesn't want Cain to heal and restore his power cuz he's against him for some reason ) tried to kill the doctor ( by hiring some crazy dude to do it ) but it turns out that he only killed a clone of the doctor ( the doctor made that clone cuz he know that people are after him ) so he eventually found his way to Cain and he was able to remove half of the thing in Cain's heart by using the main character ( which resulted in Cain being much more powerful ) and cain told him to take care of the main character so that's why he's sticking to him ( and about the pink haired dude with the doctor : he's just the doctor's friend i think he also can make barriers and stuff )

omg ily this explained everythinng <3333(づ￣ ³￣)づ
