I'm Hikaru Satonaka, 5th grade elementary school student! When I'm happy or trying to cheer myself up, my eyes light up, so my nickname is "Pikaru"! I decided to transfer to Hanamatsuri Elementary School from my grandfather's family in the next town, but as soon as I moved, I got run into by a delinquent and drowned in a river! ? The person who helped me with this was Satoru, a super lazy boy who I later found out was my classmate. However, when I tried to help her, I mistakenly thought that Daichi, a kind older brother from Tomo's same grade, had helped me...! ?
