"Overload" (オーバーロード, Ōbārōdo) is the 199th episode of Boruto: Naruto Next Generations.
Summary[]
Naruto Uzumaki instructs Boruto Uzumaki to take care of Kawaki and Himawari Uzumaki. And not to interfere. Delta lashes at Kawaki for endangering a body that, as a Vessel, isn't his. She doesn't answer Naruto's questions, so he dares her to kill him. The two trade several blows as Boruto, Kawaki, and Himawari watch. Naruto reminds her of his threat, saying it's too late now that she hurt Kawaki, so he'll go after everyone in Kara. He gets close to her, so she fires her eye beams, which he blocks with a Massive Rasengan. Delta begins absorbing it, so Naruto ups the ante by growing it into an Massive Rasengan. Boruto realises his strategy. Delta mocks Naruto for thinking she can't absorb bigger jutsu. Kawaki finds the strategy futile, but Boruto corrects him that's not what Naruto is doing. Delta realises Naruto's plan, and Boruto explains to Kawaki he's trying to overtax her absorption. Her Scientific Ninja Tool overheats, her eyes ceasing to function. Naruto explains he realised that when she fired back his Rasengan, it meant it was stored somewhere, and such storage would have a limit. Naruto boasts about his chakra reserves, and Delta tries physically attacking him. Naruto dodges it and grows his jutsu into a Massive Rasengan, landing it on her.
It carves a crater on the ground, where Delta lays defeated. The children celebrate. Naruto expresses his desire to have her questioned, so Kawaki urges to have her killed immediately. Delta's body sounds off, and self-destructs. Naruto takes the kids out of the blast radius. Delta's drone retreats, witnessed by Koji through his toad, who comments that Naruto's power still isn't enough. He's convinced the key will be uncovering the secrets of the Karma through Boruto. Elsewhere, a couple argues over doctors being unable to treat their sick son. The village is visited by Boro and his followers, where he cures those who are sick. Boro talks them into believing that salvation can be achieved through the Infinite Tsukuyomi, bringing them into his cult. Later, Code visits Boro and delivers him Amado's message telling him to come in for maintenance. Boro claims he's busy, and grows aggravated when code asks if it's fun to deceive people. Code is willing to use force to bring Boro for maintenance, so he relents. At Kara's headquarters, Jigen finishes recharging, Amado noting it's become more frequent. He reports that there have been no news about the Vessel from either Koji Kashin or Delta. From his reaction, Jigen concludes he still hasn't uncovered their mole, which Amado vows to do.
