## Premise

Yatora Yaguchi is a fairly popular student who excels in school, but secretly grapples with feelings of emptiness and frustration. After a night out with his friends, Yatora sees the morning scene of Shibuya in a shade a blue that awfully touches him. This feeling would inspire his first drawing for art class, which he normally regards as a useless subject. However, later, when visiting his high school's art club and feeling passionate for something for the first time, Yatora decides to pursue art. He eventually aspires to attend the Tokyo University of the Arts (TUA) after he graduates from high school, the most prestigious public art university in Japan. The acceptance rate is extremely low, so to pass the entrance examination, Yatora must work extremely hard.
