Continuing from the preceding OVAs with the same title, this anime delves into the everyday lives of a group of elementary school children from a 5th grade, 2nd class room as they transition into their teenage years. Amidst their adventures, the series captures their playful activities, silly pranks, and the amusing misconceptions stemming from their budding interest in the opposite sex. While Ryota Satou takes center stage as the main protagonist, his friends play equally significant roles, shaping the vibrant dynamics of their school. Particularly noteworthy are the girls, who often exude a sense of maturity beyond their years yet reveal their true youthful and mischievous nature, sometimes even surpassing the boys in unpredictability.
