Amane Shiraha. She's a girl in my class who's a bit of a local celebrity. She's kind to everyone and can't stand to see someone in trouble. She's so popular with both guys and girls that before I knew it, the whole grade—not just our class—was calling her the "Angel." ...Well, I have to admit, she really does seem like an angel. The way she gives that soft smile, her gentle voice... maybe it's also because she's always wearing that white cardigan. But that's all it was. I never actually thought she was a real angel. It was pure coincidence that I headed to the rooftop after school that day. I had forgotten my phone in the classroom and was on my way back after grabbing it. I still had a little time, so I felt like going somewhere quiet. Since the rooftop is technically off-limits, it's usually empty and a good place to rest. I pushed open the heavy rooftop door. The evening breeze, dyed in the colors of the sunset, blew past me. And then—

...Ah!
Amane Shiraha was there. With her back to the golden sky, she had quietly spread her white wings. Massive wings peeked out from the back of her school uniform. The feathers, glowing as the sunset filtered through them, shimmered white every time they swayed in the wind. I was speechless at the sight; it was far too surreal to be true. In that moment. Amane slowly turned around. It wasn't her usual gentle smile. Her eyes were slightly wide, and she let out a sharp, troubled breath.
