Kingdom Hearts: Next Generations

Kingdom Hearts: Next Generations is the second anime series of the Kingdom Hearts anime. It is the sequel to the anime, Kingdom Hearts (2015 TV series), and is followed by Kingdom Hearts: Guardians of Light. It was focused on Sora and his friends' continued battle against the Darkness. The storyline is notable for having matured the characters and taking a darker tone, with increased narrative complexity and frequency of character deaths. All main, recurring, and supporting characters have vastly different appearances compared to the first series, as a new hand-drawn animation team and style was brought in order to give the show a sleeker look.
