What is Buddy Complex about?

Buddy Complex follows Aoba, an ordinary high-school student who gets pulled into a war between mecha-piloting factions after a giant robot attacks his city. Saved by a classmate piloting her own mech, he joins her alliance and discovers a mysterious time-manipulation mechanic that links him to a pilot from the future.

How does the coupling mechanic work in Buddy Complex?

The coupling system is the heart of Buddy Complex's combat. Two compatible pilots synchronize their neural patterns mid-battle, dramatically boosting their mechs' performance. The bond between Aoba and Dio forms the emotional and tactical core of the series, blending sci-fi mechanics with themes of trust and partnership.

Is Buddy Complex connected to other Sunrise mecha series?

Buddy Complex is an original IP produced by Sunrise, the studio behind iconic mecha franchises like Gundam and Code Geass. While it shares thematic DNA with those series — real-robot combat, warring factions, and young pilots — it stands as a self-contained story with no direct continuity to other Sunrise titles.
