A story that spans 100 years across three generations of pilots, each inheriting the same mobile suit and the same war their grandfather started. Flit's character arc is the real engine here, watching him transform from a grieving child into the man who shapes an entire timeline forces you to reckon with what survival costs when you're the one making the decisions. The three-part structure rarely gets attempted in anime because it's brutal to execute, and AGE commits to it even when 49 episodes isn't enough breathing room. That constraint is real and it shows. But the ambition itself, the willingness to build something this structurally unconventional inside a franchise known for playing it safe, is why this one matters to people who actually care about what mecha anime can do.

A mysterious force known only as the UE, short for unknown enemy, strikes human space colonies without warning, beginning a war for humanity's survival. When the UE attack the colony where young Flit Asuno lives, his mother is killed, and among her belongings he finds plans for a powerful weapon from the past: the Gundam. Flit spends years studying engineering at an Earth Federation base and designing the AGE-1 Gundam, finishing it just as the UE strike again. The story spans three generations of the Asuno family, with Flit, his son Asemu and his descendant Kio each piloting a Gundam against the UE in a war lasting a century. Expect sci-fi mecha action built around giant robot battles in space.
