Большой шум с лестничной площадки

Keito Kamiyama once attended a concert of a local school rock band, all members of which were from the light music club. Impressed by their performance, the boy decided that this was what he wanted to do. After enrolling in high school, he immediately rushed to the club's doors and, without a second thought, expressed a fully enthusiastic desire to become part of it. However, it turned out that the club was run by two delinquent seniors who prohibited inexperienced juniors from practicing inside the club room. After the spring break, Keito learns that the negligent seniors were expelled from school for possessing "weed," which threatened the existence of the club. With the help of his friend Tsukumo Shintarou, Keito tries to save the light music club that he had grown to love!
