''Syrup Village Arc'' episode 15

Episode 15 ''What happened?! what was that?! did his arm extend??!!!!.....'' everyone is in shock, from when they saw Luffy's extented arm and Captain Kuro getting smacked. From the corner the Usopp pirate crew came in to take the opportunity of Kuro lying down to hit him with the bat, the shovel and the frying pan on his face. Afterwards when Kuro got up he learnt from Luffy that he possessed the devil's fruit rubber powers. At the moment where the rest were stunned for the actual existence of the rumered fruit, Kuro pointed Jango to his original role of the plan of hypnotizing Kaya and making her write the will then kill her, and as extra the 3 ants are an eyesore he should eliminate them along. As Jango was passing by, Usopp yelled to his little crewmates ordering them to protect Kaya, saying that it is their mission and it is his captain orders for they formed their pirate crew to become men able to protect what they hold dear.
Winning their acceptance with an elegant speech, the kids went to the forest with Kaya. However Kuro said that their effort is futile for he knows best how weak is Kaya's body thus they will never escape Jango while arrogantly offering him to go back them up if he's able to get past the slope alive. Desperately struggling with all his might, Usopp got up while his whole body was shaking but immediately fell down for he has since long surpassed his limites and can no longer move an inch. While laughing and making fun of Usopp, Kuro stated that it's best for him to continue lying down there since he's no match for Jango even if he caught up.
With tear filled eyes and shaking voice Usopp yelled that even if he can't he WANTS to protect them, for he's the captain of the Usopp pirates and a brave warrior of the sea, thus he won't allow them to lay a single finger on the villagers. Influenced by his determination Luffy permits Zoro to go with Usopp in pursue of Jango while he takes care of Kuro by himself. Before fighting Kuro wanted to know why an outsider like Luffy puts his nose in this village's matters, his answer was as simple as you could imagine ''because there's a man here whom I don't want him to die''. While fighting turnes out that Kuro is more skilled than thought to be for he kept dodging Luffy's attacks one after the other. As the pirates were cheering for him he raged at them not to call him by the name ''Captain Kuro'' ever again, since the plan that is being carried out at present is meant for him to completely get rid of that name. Saying that he's tired of the daily routine of planing for them whom only knew how to make a ruckus, and the government officials and bounty hunters chasing him for the reward, thus his plan which taken three years must not fail.
By countering Kuro's attack and making him lose his cat claw swords, Luffy stated that by being afraid of tha fame at sea, Kuro is not qualified to be a pirate and he'll never lose to him since his ambition is much greater that his.
