True Calendar (T.C.) 71 - A new age where 70% of the human population lives in space. Haruto Tokishima lived an ordinary life as a high school student in the division known as 'Module 77'-until the Dorssian military begins their sudden invasion!
Enraged by his loss, Haruto uses the Valvrave to seek vengenance against the Dorssian Military. But an equally furious A-drie stands up against the attack and quickly overwhelms the inexperienced fighter.
L-elf tells Haruto to make a pact with him. ARUS kidnap Haruto and attempt to escape without saving the students of Sakimori. Shoko imparts the plans of ARUS to the student council. Not willing to depend on others, Sakimori students declare independence.
L-elf is finally reunited with Lieselotte, however the students find themselves surrounded with Captain Cain having predicted their every move. Saki Rukino also finds herself cornered, and Haruto learns the surprising truth about the Magiuses.
Haruto proposes to Saki, since he feels guilty about what happened between them. The school is under Dorssian attack. Haruto asks L-elf to drive the Dorrsians out. Shoko attempts to rescue Akira who refuses to go outside. Cain confronts L-elf.
Module 77 is headed to the Moon and the students have begun military drills. Thunder has sworn revenge but he is put in solitary confinement. Thunder and Inuzuka decide to pilot their own Valvraves and help Haruto and Saki battle against the Dorssians.
With Earth fast approaching, only Akira, the former shut-in, has yet to become friends with the others. Satomi is over-protective of his little sister to atone for his past actions, but even that gets on her nerves. Their plan appears to be going...
When Saki got on Valvrave IV, she took the same ability as Haruto. She causes a confusion using her ability. Soon after, Dorssia fleets begin to attack against Sakimori.
L-elf is held in interrogation but he manages to escape. Haruto makes a triumphant return and is considered a hero by the masses for taking on the Dorssian military. Haruto has a meeting with Senator Figaro.
Since Shoko declared independence, the students of Sakimori have been leading a carefree lifestyle. All of a sudden, the power goes out. Finally, the students manage to turn the power back on, and they broadcast a video of themselves singing a song.
