The day had started well. Uzui woke everyone up shouting and singing at 6:08 in the morning. Right after, everyone went to have breakfast and chat as usual, but something was wrong. The crows seemed... to be talking? As if they were discussing something or someone, but nobody paid any attention.

A girl with black hair, pink streaks, and disheveled like a bird's nest entered huffing, wearing a rather conspicuous uniform and with dark eyes gleaming with arrogance.
