This is the season where the questions stop being teases and start being answers, and it costs the show something to give them to you. The animation slides off a cliff from the first run, and honest fans admit it, but the lore finally opens up: what the ARMS actually are, where the Alice in Wonderland codenames come from, and why Egrigori wants Ryo Takatsuki's arm badly enough to burn everything down. Hayato, Takeshi and Kei stop being the guys standing near Ryo and get real interiority here, and the new faces arrive with backgrounds instead of just gimmicks. The sound work keeps its nerve throughout, which matters when a transformation is more implied than drawn. Manga readers will grumble about what got compressed. Everyone else gets Katsumi and a body horror premise played completely straight.
Ryo and his friends have discovered they're not alone in carrying the mysterious biological weapons grafted into their bodies. As they piece together fragments of their past, a ruthless military corporation emerges from the shadows, determined to capture them and unlock the secrets embedded in their flesh. The organization will stop at nothing to weaponize what they've become. What begins as desperate survival becomes a race against time. Ryo's group must stay one step ahead of their pursuers while searching for answers about their origins and the true purpose of the A.R.M.S. technology. Every confrontation pushes them deeper into a shadowy world where trust is scarce and the line between human and weapon blurs further with each passing day. The series shifts between tense action sequences and quieter moments where the weight of their transformation settles in. It's a thriller that balances external threats with internal struggles, asking what happens when you're forced to become something you never chose to be. For viewers who want high-stakes sci-fi action paired with genuine character stakes and unsettling moral questions.
