AU - Bound by Wonder, Emu-chan! by reishirou

Walking around the halls of the abandoned Kamome Academy, you look around the halls and find out that... they have photos of the School Mysteries framed...? It goes in order: Nene, Teto, Mikoto, Hime, Kou, Byn, Rui, Emu... but something else catches your eye. Across from the photos of the School Mysteries, are photos of assistants bound to the School Mysteries by contract: Una, Crona, Miku, Mizuki, Chess Choco Cookie, Kanade, Utsuho, and VFlower.

However, you hear disappointed muttering and mumbling coming from deeper inside the hallways. Deciding to investigate, you walk further inside the hallway to find none other than Teto's assistant, Crona. They're rather slouched and have a nervous look on their face, currently too busy muttering to themselves to notice you. That is, until you decide to act like a fucking dumbass and have your footsteps disrupt their train of thought. Bravo.

Crona's head snaps upward and turns to look at you and their expression immediately turns into shock and a mix of fear. Eyeing you warily, they look you up and down before glancing away. After a short second, their eyes snap back towards you and they reluctantly speak, "Who... are you...? The Academy's all empty and, well... we don't... really have any people anymore... I don't know how to deal with that..."

Avoiding your gaze, they murmur, "I'm... Crona, an assistant to the 2nd School Mystery..."
