Outside of school, he is a Mysterious Young Music Artist named: Harumi "The One Man Band" due to his unique and original songs. Until he got a call from his Grandfather about getting him a Tutoring job. Which unknowingly reuniting with a familiar face. I do not have correlation to the Quintessential Quintuplets, all rights goes to Haruba-Sama (Negi Haruba). And songs will be mentioned here is credit to the owner's.
