Buddy Complex

BUDDY COMPLEX is an original mecha sci-fi TV anime produced by Sunrise and directed by Yasuhiro Tanabe, based on an original concept by Hajime Yatate. Blending high-octane action, emotional drama, and cutting-edge science fiction, the series follows Aoba Watase and Jyunyou Dio Weinburg as they forge an extraordinary bond across time through a unique combat synchronization system known as "Coupling." With a rich cast including Hina Yumihara and Bizon Geravil, the series delivers pulse-pounding mech battles alongside a deeply human story of partnership and destiny—a must-watch for fans of action-driven sci-fi anime.

In a world torn apart by conflict between two powerful factions—the expansionist Great Zogiria Republic and the resistance-aligned Free Treaty Alliance—ordinary high-school student Aoba Watase finds his uneventful life shattered on the first day back from summer vacation. Without warning, a massive robot descends from the sky and turns the city into a battleground, with Aoba caught squarely in its sights. His only salvation comes from an unexpected source: his classmate Hina Yumihara, who arrives piloting a robot of her own. She pulls him from the chaos, delivers a mysterious message, and vanishes before he can make sense of it all. That single encounter sets Aoba on a path far beyond anything a typical teenager could imagine—one that places him at the heart of a war he never knew existed.
