Danbooru の英語定義
One of Monkey D. Luffy's transformations from One Piece. Luffy coats his arm in Haki (one piece) before biting into his forearm. Similar to how he activates Gear Third, he blows an incredible amount of air into his body, but this time he inflates his muscular structure before distributing the air throughout his body, with emphasis on his upper half. If Luffy is stopped mid-blowing, the arm will slowly deflate. When utilizing Gear Fourth, Luffy makes extensive usage of his Haki (one piece) by coating his arms, legs and much of his torso in it to the point that they turn black from hardening.
