Bakumatsu Rock
Ryouma Sakamoto wants everyone to be familiar with his passion for rock 'n' roll, therefore he roams around town together with his electric guitar eager to demonstrate anyone he encounters that he's equally as skilled as the renowned Shinsengumi celebrities they admire. Regrettably, Japan doesn't allow anything aside from the Heaven's Songs of that group, for performing or writing different kinds of music and can cause harsh consequences.
Agitated by these strict rules and brain washing, Ryouma does what he can to show people that provides them. Along Kogoru Katsura and his Shinsaku Takasugi, Ryouma works hard to find places due to his rock'n' roll group to execute side. The trio begin to appreciate than they had thought, that there is more for their passion.
