Mukuro

ムクロ

The man who grew up with Mugen in the Ryuukyuu Islands alongside his little "sister" Khoza. A ruthless, traitorous pirate who left Mugen to face the consequences after they robbed a Satsuma ship carrying raw sugar. He is encountered again by the trio in episodes 13-14, "Misguided Miscreants Parts 1-2," where he and his pirate crew attempt to rob and murder the trio, though they are easily thwarted by Mugen and Jin. He proposes to Mugen that they work together once more, promising him vast riches consisting of gold coins. Though Mugen initially refuses, Mukuro wears him down with a contest and once again pulls the same stunt he did in the past.
