Kawaki

Kawaki is a major character introduced in the Boruto: Naruto Next Generations series (the sequel to Naruto).

• He is a teenage boy with a tough, stoic, and initially very hostile personality.
• Kawaki was raised as a human weapon/tool by the criminal organization Kara under the direct control and modification of their leader, Amado and later Jigen/Isshiki Ōtsutsuki.
• His body is heavily modified with advanced scientific ninja tools (particularly the large black Kāma seal on his left arm and upper body), which grants him powerful abilities including immense physical strength, body manipulation, absorption of ninjutsu, and access to Ōtsutsuki-level powers when the Kāma is active.
• He carries deep trauma and a strong hatred toward "Otsutsuki" beings and the concept of ninjutsu itself, famously stating his goal as "I'll send Naruto to hell" (referring to ending the shinobi system and the Ōtsutsuki threat).
• After being taken in by Naruto Uzumaki, he gradually becomes part of the Uzumaki household and develops a complicated older-brother/rival-like relationship with Boruto.

In short: Kawaki is a brooding, extremely powerful, tragic anti-hero/villain-turned-ally figure whose defining traits are his traumatic past, immense combat ability, and complex bond with Boruto and Naruto.
