Juuou Mujin no Fafnir

Synopsis

Yuu defeats Kili in a fight to decide Tear's fate, thus his plan to destroy Basilisk goes forward. As part of the agreement, Yuu orders Kili to live on as a human. Kili kisses Yuu as she leaves asking him to prove his superiority to dragons by defeating Basilisk. Mitsuki devises a strategy to defeat Basilisk with all possible scenarios planned out. The Mistileteinn is dropped with the students dropping with it. The students protect it from the first catastrophe beam discharge by Basilisk's third eye, but with the discharge occurring much sooner than the first drop that the third eye had time to fire the catastrophe beam a second time, which destroys the Mistileteinn. However, the blast creates an opportunity for the students to disable the third eye during its recharging period. The students immobilize Basilisk, and Basilisk is destroyed by Yuu using Babel. The students return to Midgar as Mitsuki's outlook on life has changed to a more optimistic one. Yuu reveals the truth about his contract with Yggdrasil and memory loss to Iris. In response, she vows to stay with him and to never forget the memories they made with each other. (Source: Wikipedia)
