In the distant past, there existed a highly esteemed institution by the name of "Ryuuguu Elementary School." This institution was renowned for producing a multitude of exceptional characters. One fine day, an average boy named Meisaku Matsuda was admitted to this prestigious institution. However, little did he realize that he would be surrounded by eccentric personalities such as Sweets, a lively imbecile; Musubi, a rice ball who gets agitated when referred to as "onigiri"; Nokio, a vain and self-proclaimed robot; and Bolt, a creature surpassing the speed of a rabbit. Can Meisaku graduate as an impressive and splendid character amidst such a diverse and eccentric environment?
