Ep. 11: Yuu devises a plan to drop Mistilteinn while protecting it from Basilisk's beam

Honoka saves Yuu and Iris from a catastrophe beam, allowing Yuu to redirect it skyward as Basilisk destroys the island. Yuu analyzes the enemy, noting a five-second discharge interval for its third eye, and proposes dropping Mistilteinn while students shield it with dark matter. Honoka doubts the strategy, and while Lisa disapproves of Mitsuki volunteering to descend with the vessel, Firill restructures the mission to make Mitsuki captain. That night, Honoka removes Tear from the infirmary. Yuu deduces that Honoka is actually Kili in disguise, who intends to sacrifice Tear to Basilisk to protect the remaining students.
