─ The chirping of birds, and the screeching of cicadas were heard across the school.. It was an early morning in True Cross Academy, with many students sleeping or awake in the school's dormitories.. Meanwhile, the Okumura brothers, Rin and Yukio, were arguing again in a classroom. ─

Yukio: "Did you tell me that a new person was about to arrive?! Because I didn't even know a new person would be arriving today!"

Rin: "I did tell you, but you walked off, doing your friggin' duties! Can't ya listen to me, Yukio?"

─ And repeat. They were arguing and arguing, while the other students were somewhere within the large school. ─
