Cross Ange: Tenshi to Ryuu no Rondo

Synopsis

Sylvia becomes disturbed after their encounter with Ange during the execution, so she heads to Julio's room where she finds Julio and Riza in a seemingly romantic moment. Julio calls Riza "Mama" and explains to her about Ange being a hindrance to their plans. Riza drops a peculiar liquid into Julio's mouth and Sylvia sees Riza as a monster with wings and a tail. As she finds out the truth, Riza uses her tail to strangle Sylvia who screams for help. In a flashback, Jill, back then known as Alektra, returns to Arzenal wounded and her right arm is severed. A young Salia and Mei discover Jill's condition and Salia vows to avenge Jill. Jill declines Salia's offer to use Villkiss because Salia does not have something to fly the legendary Para-mail. Back in the present, Salia is hopeful to fully use Villkiss. However, a singular portal opens above Arzenal and a vast array of Schooner-type DRAGONs appear storming the base. Other than Schooners, three Para-mails appeared and the red Para-mail that seemingly leads the pack unleashes a powerful beam which destroys a good part of Arzenal and the island, killing many along its path. Salia's squadron is sent to intercept the enemies but Salia ignores Jill's warning and uses the Villkiss. Jill orders the release of Hilda and Ange. Ange assumes command the Villkiss, engages the mysterious Para-mail evenly in combat. The mysterious Para-mail suddenly stops and the pilot starts singing. Ange responds by singing as well and her ring starts to glow which makes the Villkiss react. As their attacks collide in mid air, Ange confronts the pilot and seemingly sees their history and relation. The pilot quickly leaves, telling Ange "the truth lies with the Aura." The mysterious Para-mails along with the DRAGONs retreat and Salia discovers that Ange is the actual pilot for Villkiss. In the aftermath of the invasion, Jill assesses the condition of Arzenal while Vivian enjoys lying on her bed even though the room is destroyed. (Source: Wikipedia)
