Ryōta is the protagonist of the series and the childhood friend of Chika, having a crush on her ever since. In the past the two often played together, even sleeping together in the same bed, and promised to marry each other once they had grown into adults. He is best friends with Kōji and good friends with Tsubasa Kawai and often challenges Kōji to see which of the two is better. He enjoys eating and playing games together with the rest of the class. Although he is not very intelligent, he is a kind person and tries to help others when he can, which often unwilling and unintentionally trap him in compromising situations that earn him a beating from either Chika or Yūki. He is naive to the desires of normal males as he is not especially interested in relationships between males and females. Once he falls asleep, it is extremely hard to wake him up. Not only that, he is also a bad sleeper as he frequently rolls around in his sleep. His seat number is 12.     (Source: Wikipedia)

Following the line of the precedent OVAs (of the same name) This anime goes around the normal lifes of some elementary school (5th grade, 2nd class room) kids and their adventures, while turning to teens. Their games, stupid jokes, and the misunderstadings around their premature attraction to the opposite sex. Ryota Satou is the main character here, but his friends are almost as important as him since the school wouldn't be the same without them, specialy the girls who the majority of time appear to be mature by their ages but in the ends they are as childish and even more "dangerous" than the boys.
