The two part finale of Buddy Complex television series deals with the final battle between the Free Treaty Alliance and the space division of Zogiria, lead by an elderly Bizon, as Earth and time itself hang in the balance.

When ordinary high school student Aoba Watase is suddenly targeted by a giant robot known as a "Valiancer," he is saved by his mysterious classmate Hina Yumihara. After revealing that she and their robotic enemy are from the future, Hina suddenly propels Aoba 70 years forward in order to prevent his death. Upon arrival, Aoba finds himself in the cockpit of a Valiancer called "Luxon," stuck in the midst of a firefight between the military forces of the Free Pact Alliance (FPA) and Zogilia Republic. After he shows high compatibility with an FPA pilot named Dio Weinberg, the two perform a successful "coupling," allowing them to share experiences and subsequently increase their capabilities and skills. Although Aoba is able to survive this unexpected battle, he is taken into custody by the FPA ship Cygnus, who wishes to interrogate him. While the student's main concern is whether he will ever be able to return home, what he doesn't realize is that he is about to get caught up in a war to protect the world. [Written by MAL Rewrite]

Toua Tokuchi is an athlete by profession, but a reckless gambler at heart. On the streets of Okinawa, he uses nothing but his wits and a "fastball" peaking at a mere 134 kmph to somehow achieve 499 wins in the game of "One Outs," a simplified version of baseball between the pitcher and one batter. Amazed by Toua's unique prowess on the mound, veteran slugger Hiromichi Kojima artfully scouts the pitcher for his long unsuccessful team, the Saikyou Saitama Lycaons. Kojima desperately hopes Toua will lead them to the championship; however, Tsuneo Saikawa, the mercenary owner of the Lycaons, sees the vastly talented pitcher as a threat to the income generated by the team. Rising to the challenge of swaying the owner, Toua suggests a one-of-a-kind "One Outs" contract: every out Toua pitches will earn him five million yen, but with every run he gives up, he will lose fifty million yen. Adapted from the manga by Shinobu Kaitani of Liar Game fame, One Outs documents the intense psychological battles between Toua and those around him. With millions of yen at stake, can a pitcher who has done nothing but gamble in a head-to-head imitation of baseball finally lead a real baseball team to victory? [Written by MAL Rewrite]
