It grabs you by the collar in episode one and never really lets go: Ikki barely lands back in Japan before armed men are on him and Kogane comes in swinging the living weapon fused to her right hand. Sanzigen went full CG here, and it earns it, because the Buranki don't fight like puppets, they fight like heavy machines with weight and bad tempers. The best idea in the show is that Oubu isn't piloted by a chosen boy alone. It's crewed, limb by limb, heart included, so every brawl is also a group of stubborn people trying to move as one body. Reoko and Entei exist to remind you what that looks like when the wiring goes wrong. Watch it for the noise and the momentum, stay because a weapon that has its own mind will absolutely decide it doesn't like you.

Azuma Ikki comes back to Japan after ten years away and is promptly attacked by a band of armed men who take him prisoner. His childhood friend Kogane Asabuki frees him using a Bubuki, a weapon with a mind of its own that she wields on her right arm. Ikki soon discovers that he can use Bubuki too. Joined by his new companions, he sets out to find and revive a Buranki, a titan resting deep underground, and in doing so opens a path toward the truth about these giants. The 12-episode series mixes mecha action, drama and science fiction.
