What's the name of one piece's skull?

Brooke; It's called nasal song brook. He is a character in the Japanese cartoon One Piece and its derivative works. Now he is a musician of straw hat pirates. He was originally the head of a national guard, and later joined the Lombard pirates. Fifty years ago, he and the whale Bula agreed to meet again at Gemini Point. Later, in the devil's triangle, I met the enemy, because of the ability of Huangguo;

When the soul came out of the grave and was ready to return to the body, he was lost in the devil's triangle for a year. The found body has become a skeleton, but the explosive head still exists. From then on, he can only live as a skeleton. After the Battle of Ghost Island, I learned from Lufeikou that my partner Bula is safe now. In order to fulfill the agreement with Bula, I officially joined the Straw Hat Pirates.

Character setting-

The ninth member of the Straw Hat Pirate is a musician. The resurrected person can be resurrected once after death, because the fruit has completed its mission and he can't swim. Characterized by skeletons, dressed as gentlemen, with a pair of explosive heads, like music and know many musical instruments. Sexy and funny, the first sentence when meeting a woman is "Can I admire your underwear?" The unique laughter is "yo, hehehe".

Because he is a skeleton, he is light, can walk on the sea and has high jumping ability. He used to be the head of the guard, so he is good at fencing. His crutch is a double-edged sword and a very powerful swordsman. The names of moves are mostly music types and fencing terms. The crack on his forehead is an old wound before his death. His favorite food is milk. He believes that drinking milk can cure fractures and restore physical strength. He is the oldest and tallest of his companions.

Brooke's double-edged sword, which he took with him when he first entered the arena, was a crutch in appearance. Because the sword has no back, when it is not necessary to draw the sword, the blade will be put in the crutch-shaped scabbard. Because Brooke's skill is very good, this sword can also be used to play the violin.
