The story reaches its conclusion as Tusk, Hilda and Salia team up to rescue Ange and make one last stand against Embryo in his dimension.
Tropes in this episode include:
- And This Is for...: Tusk kills Embryo to avenge his parents and the Ancient Humans, all while channeling his inner Domon Kasshu.
- Attempted Rape: Embryo does one last attempt to violate Ange before she starts singing the "Endless Song".
- Badass in Distress: Yet again, Ange is captured by Embryo and is stuck in his dimension.
- Be Yourself:
- Salia has to key into her emotions to activate her Ragna-mail with Salia gaining Villkiss's Ariel teleportation mode.
- Hilda, also keying into her emotions, unlocks hers, gaining Villkiss' Michael BFS wielding mode.
- Became Their Own Antithesis:
- Ange began the series as a naïve princess promising herself she would wipe out all Norma and uphold the peace and prosperity of the decadent Mana society. By the end, she's a hardened Norma soldier who scornfully disregards that her former homeworld (and everything it previously stood for) is in ruins and anarchy. She's also sided with nearly everyone she was previously against (the Normas, the DRAGONs and the Ancient Humans) and is set on creating a peaceful co-existence with all three parties.
- The same could be said for the Mana society as a whole. It was previously a utopic world of peace and harmony, a world that callously looked down on normas for being allegedly violent and anti-social. The last we see the Mana society, they've become everything they accused normas and pre-mana humans of being: a broken society of violent and anti-social anarchists without mana.
- Big Damn Heroes: Tusk, the Norma on the Aurora and the DRAGONs come to Ange's aid in the nick of time.
- Bittersweet Ending: The Norma and the DRAGONs return to the true Earth to help Ange finally kill Embryo, stopping the dimensional merge and undoing his reign of terror, and Libertas is a success. However, Ange and Sylvia are estranged, Jill is dead, and the humans in the false Earth have to live without their powers. With that said, the Norma and the DRAGONs look forward to a new future of peace and harmony.

- Hourglass Plot: At the beginning of the series, the Misurugi Empire was a prosperous utopia of peaceful mana users, while the normas are exiled to live in the "hell" that's Arzenal.

- Nice Job Fixing It, Villain:
- Embryo trapping Ange in his dimension means that she can sing the "Endless Song" to summon the Villkiss.

Then, Ange says "You wanna screw with me again? Give it a few thousand years!" and destroys Hysterica for good.
- Pyrrhic Victory: While Embryo severed the mana network, he failed in his ultimate goal to use Ange in creating a new humanity and merging the two worlds together.
