Storyline

Twenty-five years ago, the world suddenly changed when monsters called “Dragons” appeared; seeking to ravage the earth and find mates. Over time, superhuman girls possessing the powers of the dragons, called “D girls” were born. Yuu Mononobe is the only male “D” in existence and is forced to enroll at Midgar - an academy for D girls. At the academy, he accidentally runs into Iris, a delinquent D girl, while she’s naked, and even reunites with this long lost sister, Mitsuki, whom he was separated with at birth. Will Iris and Yuu, the boy who is supposed to become the strongest assassin, be able to challenge the seven dragons that threaten to destroy the world?

After the Dylan's plan has gone awry, the execution of a new operation is entrusted to the Midgar. Having analyzed Basilisk's third eye, Haruka gives an overview of the new strategy to the students of class Brunhild, which is to form pairs and launch a strike on Basilisk, by infiltrating the volcanic island. She orders them to carry out the attack before the catastrophe beam can be fired. For this operation, the pairs consist of Yuu and Iris, Mitsuki and Ariella, Lisa and Ren, and Firill and Honoka.

The island is destroyed by Basilisk and students retreat back to the ship. After analyzing the attacks, Yuu determines that its third eye cannot fire the catastrophe beam in quick succession and its discharge time is five seconds.

Yuu defeats Kili in a fight to decide Tear's fate. As part of the agreement, Yuu's plan to destroy Basilisk goes forward and Yuu orders Kili to live on as a human. Kili kisses Yuu as she leaves asking him to show his superiority by defeating Basilisk. Mitsuki devises a strategy to defeat Basilisk with all possible fallback scenarios planned out. The students drop with the Mistileteinn and protect it from the first catastrophe beam discharge by Basilisk's third eye, but with the discharge having come much sooner than anticipated that the third eye had time to fire the catastrophe beam a second time, which destroys Mistileteinn. However, the blast creates an opening for the students to disable the third eye and immobilize Basilisk, allowing Yuu to destroy Basilisk using Babel. The students return to Midgar as Mitsuki's outlook on life has changed to a more optimistic one and Yuu tells Iris about his memory loss as a condition for using Babel, and Iris vows to stay with him.Less
