--July 13th
Not long after Onyx's death, the three of us went back to the ruins of December City. There, we buried Onyx Faustnoir next to her old friend, Nicholas D. Wolfwood. We buried her beloved jasper revolvers with her.
Eventually, we reached Augusta City, where we met up with Meryl and Millie. Shiro stuck around for a while and then went back to New Miami saying something about checking on his "business". I soon got over Onyx's death; I figured that was what she'd want…but such was not the case with Knives.
My brother was heartbroken. He had fallen deeply in love with Onyx only to see his world crumble before his very eyes. He was broken both spiritually and mentally. We frequently tried to help him, but he locked himself in his room, and spent days scouring over a strange book that he refused to let anyone else touch.
Then one morning, Knives simply disappeared into the desert without telling anyone. That was three months ago, and there has still been no word from him. Even Shiro is unaware of his whereabouts.
My guess is that we will never hear from him again…I hate to give up hope, but I saw the look in Knives's eyes when he saw Onyx lying on the floor of the church in a pool of blood…and frankly, I think that Knives went off into the desert to die, to sleep. I think that life without Onyx, knowing that there was nothing he could have done to save her, had become too unbearable for him and that he just had to end it alone…I don't really know any of this, but I do know my brother, and when last I saw him, he was already a dead man; in soul if not in body.
