With the students in the catastrophe beam's line of fire, Honoka uses her power to get Yuu and Iris below the beam, while Yuu fires an anti-gravity bullet to direct the beam safely into the sky. 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. As such, Yuu comes up with a new strategy that involves dropping Mistilteinn, but with the students using dark matter to protect the Mistilteinn from the third eye's catastrophe beam for five seconds. Honoka shows her concerns about whether or not the plan will work, while Mitsuki decides that she will descend with the Mistilteinn, a plan Lisa expresses her disapproval of. However, Firill comes up with a better plan that makes Mitsuki the captain of the operation. That night, Tear is taken from the infirmary by Honoka, who Yuu figures out is actually Kili, and she intends to feed Tear to Basilisk to spare the other students.
El ataque desde la isla falla, pero todos logran salir con vida. Mientras Mitsuki intenta elaborar una estrategia para lograr que Lisa la perdone, Honoka desconfía de ellas y decide hacer algo por su cuenta.
