Ep. 16: Fuerzas extranjeras irrumpen en la academia, amenazando la cirugía de Rihito y obligando a la clase a luchar por su supervivencia.

Murdoch, unwilling to risk Alcia never existing, decides to stop anyone interfering with Rihito's surgery. Doan steals Sonohara's remaining star, claiming she is too weak for war, so getting her expelled will save her. Murdoch lectures Sonohara for relying on Rihito instead of growing stronger, but gives her one of his stars. Lynn admits she loves Licht. Hina decides to let Rihito become Licht but prevent him killing so he never develops his Schmelman personality, and Alcia will still be created after the war. Pele almost admits he loves Lynn but a foreign country suddenly attacks the academy, which shouldn't be possible due to Althing banning war. Soldiers begin slaughtering the students but Doan saves Sonohara while Murdoch saves most of their classmates. Firenda realises that of the seven ballots needed for an Althing vote, four are in foreign nations, meaning they must have secretly voted to allow war again. The enemy cuts off the electricity, risking Rihito dying from the incomplete surgery. The entire class fights their way to the emergency generator, many of them becoming injured or killed and Alan receives his future trademark facial scar saving them from a rocket. Rihito's hair turns white as he begins to die. Hina is caught by a soldier and calls out for Licht. (Source: Wikipedia)
