Draken, even though the girl he loved died such a miserable death, he still managed to pull himself together and lived properly, he stayed strong until the end, even though we know he was suffering alone. In a certain sense he accepted Emma's death as she's already dead and nothing can be done about it, but he couldn't accept Mikey's situation, he still wanted to help him out of his emo-ness and I don't know what else that caused him to become the person he is now, which lead to his death (yeah Takemichy contributed greatly here by foreseeing Senju's death, I wish he didn't foresee anything at all!!). While there was a death flag upon Draken's head from the beginning and after Emma's death, I had a bad feeling when he lied to Takemichy about Mikey's whereabout in the present time line and then told him to leave Mikey alone, we know he couldn't have just accepted Mikey's fate that simply the way others like Naoto did so we knew somehow he'd be involved.
Shit I know it's all the killer's fault but I can't stop blaming Mikey and Takemichy as well!
Man why are you doing this!!
You're killing all my favorite boys!! I'm not even done crying over Draken's death and you're already killing all the best boys.
