Yukina is trapped in a pitched battle against Astarte the homunculus, and she's losing—when who should come to her rescue but the very boy she's been assigned to observe, Kojou Akatsuki! Kojou tries to end the clash, but Astarte's familiar, the fearsome Rhododactylos, isn't going to let that happen. Is this a fight that only an awakened Fourth Primogenitor can finish?

As the fight against the armed apostle continues, Kojou's familiar began acting erratically, ending the fight early. The next day, Natsuki summons him and Yukina to the guidance office.

Kojou and Yukina discover a homonculus tuning vat in the lab. They soon encounter Rudolf and Astarte, and learn their plans. A fight ensues, and Kojou takes a fatal hit.
