Gundam Wing: The Endless Waltz

“History is much like an endless waltz. The three beats of war, peace, and revolution continue on forever.”

Heero Yuy (Hikaru Midorikawa) and the other four Gundam pilots want what the war never allowed them, which is an ordinary life, and a year into the peace they have sent their machines into the sun. Then Relena Darlian, now a high-ranking government official, is kidnapped by a colony set on dominating the Earth Sphere. Yasunao Aoki sends the pilots back into action with nothing left to fight in, and the peace they gave up their weapons for is what they stand to lose.
