Ambition! Successor to the Throne

Nanael makes her report to Heaven, where the Head Angel determines that Aldra has made a pact with Delmora, a fallen angel. The final battle begins, with Aldra proving to have overwhelming power. She eventually kicks Leina in the neck, making her collapse. Risty appears at the arena and cheers Leina on, causing her to get back up. Leina shows that she has adopted many of her old foes' techniques as she hits Aldra with Claudette's Thunderclap Strike and Tomoe's Warrior Kick. Just as Leina has the advantage, however, Aldra petrifies her. The crowd jeers, calling her a demon. Meanwhile, Lana has invaded the palace, trying to rescue his parents by himself. He is confronted by a Fang Assassin, but finds Airi's Scythe which still contains some of Airi's spirit. He hurls the scythe at the Assassin, and Airi snags enough of the Assassin's vital force to reconstitute herself. Nanael overhears the struggle and arrives with more sacred milk, freeing Cattleya and Owen. Melona has been hiding in the palace, though now she is tiny, and Menace is also freed. Aldra flies into a rage at the crowd's jeers and petrifies them all except Claudette, Tomoe, and Risty. Even though Leina is petrified, her spirit causes everyone's weapons to glow: even those far away like Nowa and Echidna, showing the bonds she has formed with all of them. Nanael frees Leina with more sacred milk, and she counterattacks. Delmora convinces Aldra to remove the seals on his power, but even with his unsealed power, Leina defeats Aldra, causing Delmora to emerge. It is revealed that Delmora separated Aldra from her sister so that she would despair and seek to use his power for revenge so that he could get her body in return. Nyx sees that some of those petrified have been freed, and finally shows resolve of her own by freeing Funikura herself. Nanael pours more sacred milk on Delmora, then Claudette, Tomoe, and finally Leina attack, defeating him as Leina emerges victorious. Aldra matures to adulthood in an instant since Delmora had given her eternal youth, and Tomoe tells her that she can seek her sister in Hinomoto herself. Soon after, Leina is crowned the new Queen.
