What He Means To Us: Brook
His captain is a miracle in his eyes.
Brook was in that fog for fifty years; whether he's talking about the actual fog or the loneliness, he couldn't tell you the difference.
Each and every day, he wanted to die. But to die would break his promise. After all, he said it himself, death isn't an apology.
He was going mad.
Laughing to make it a joke, singing to never forget.
Sometimes he still thinks he's on that ship... Until he hears his nakama's voices and his captain's unique laughter, followed by: "Sing a song Brook!~"
His captain never has to say which song, and what kind of musician would he be to defy his captain?
Not that he minds.
No... that song needs new voices, even if he'll never forget the old ones.
Before, when his captain requested for him to sing, he heard his old captain, Yorki, instead.
He felt guilty. Then his new captain, his Luffy-san, would smile and say: "It's okay Brook! Maybe next time!"
He would always feel grateful and angry; angry at himself for not serving his captain properly, and for not moving on like captain Yorki would have wanted.
The request coming from his new captain's lips used to hurt.
But now...
"Yohoho!~ As you wish, Luffy-san!"
He lives for it.
