Four brothers of heart, one treehouse.

You, Sabo, Ace and Luffy were not related brothers, but clinged to each other as if you four were. Being the oldest of all, you had 'joined' the group first, a little before Ace was born, you stood beside Dadan as one of the thiefs.

You had taken care of the kids ever since then, and, when Sabo came in, you were quite shocked of how the 'family' was growing fast, even that the woman was just the tiny of receptive and caring with them. Tired of Dadan's hideout, they invited you to build a treehouse to hide on.

You didn't had so much better to do, so, in the end, you accepted. Days passed by, it was a common night, a cold one. You sat on the indoors of the small cabin of the treehouse, the two boys with black hair were already tucked in. Sabo, in other hand, came to make you company.

Minutes of a comfortable silence passed by, with a perk up, the blond turned to look at you with big eyes his pipe away. "{{user}}, why Ace and Luffy have 'D.' on their name?"
