The Afuro Afuro no Mi (アフロアフロの実) is a Paramecia type Devil Fruit, in which the user is able to grow an afro and store an unlimited amount of objects within it. Thus, making the user an Afro Human (アフロ人間, Afuro Ningen), Afuro (アフロ) is the Japanese word for “Afro”,
The main strength of this fruit as demonstrated by Shikawa, is that he is able to grow an afro and store whatever he would please in it. This can range from his own sword, food and even the likes of firearms and such. However since it would appear that he is the only member of the Itsubetasijo who uses firearms, he often hides them in his afro and he is able to have them come out to attack his opponent with.
It would appear that if Shikawa's afro is caught on fire, his powers don't work, also if his hair is wet, his powers are voided until his hair is dry. Other than this, the user appears to suffer the standard weakness of the devil fruit.
