Ninjin is one of the three children who once formed the Usopp Pirates in Syrup Village, alongside Piiman and Tamanegi, before Usopp left to sail with the Straw Hats. He stood by the crew during the Syrup Village Arc and later kept up Usopp's tradition of crying pirate.
Ninjin is a freckled youngster whose spiky purple hair tumbles over his eyes, topped by a red, frilled hat bearing the Usopp Pirates flag. Combined with his sharply pointed chin, the hat and hair give his whole head a carrot-like silhouette. He rounds out the look with a black sweater, a reddish-brown sash, pale orange trousers, and dark brown shoes. Two years on he has gained height and his hair has settled flatter, and he switches to a light hooded jacket with buttons, black calf-length pants, and laced black footwear.
Fierce loyalty to Usopp defines Ninjin, and he has the nerve to back it up, squaring off against Jango to shield Kaya from harm. For the future he holds a simple ambition of his own: he hopes to run a bar once he is grown.
The Usopp Pirates came together five years before the start of the story, with Ninjin, Tamanegi, and Piiman joining Usopp in spinning tall tales. He first turned up in Syrup Village as the Straw Hats arrived. When Captain Kuro plotted to murder Kaya, the trio helped her flee, mostly by darting away from and hiding from Jango, whom Kuro had dispatched to coerce her will. Wielding a frying pan, Ninjin proved quick and tough enough to dodge Jango's blows during the clash with the Black Cat Pirates. After Kuro fell, the young crew disbanded in tears once Usopp set off to become a genuine pirate, and the children resolved to keep up his cry that pirates were coming. In later years they chased Jango out of the village, celebrated Usopp's bounty as Sogeking after Enies Lobby, recognizing him by his nose, and eventually gathered with Kaya at her mansion to hear Vegapunk's worldwide broadcast.

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
