[Machine Translation] ( Bye, bro ) - Kirino said goodbye and departed from me. ...I'm not really sad about it. And then the new semester. I'm enjoying a peaceful high school life, when a strange junior appears in my life. ( Good morning, senpai ) I learn Kuroko's first name as a human, and we form a deeper bond. A sister and a best friend. Both of them have lost something big, and they face a girl with a "magic eye" in the school, where many thoughts are swirling around them. The girl with a rare ability overwhelms me and Kuroneko, and leads us into a different space...! The story begins when "everyday" and "extraordinary" intersect.
