Yesterday Never Ended

Halyn High. The famed school of Allard City filled with bright and unique students and enough functions to make one's head spin.
Everything was calm until one day a boy by the name of Akio Deutelas returned to its halls. From that day forward, everything changed and a new trio of friends was forged.
This is the story of that school and all the students in it. And this is the story of Akio, Luna and Grey. The three students that turned Halyn High on its head.
