Komari is a smart, but insecure girl who wants to be seen as a woman, although she gets easily annoyed by the fact that Hotaru Ichijō both looks and acts more grown-up than her, despite only being in fifth grade. Komari often feels out-of-place among her younger schoolmates, sometimes scorning them for their childish behavior. Komari never asks for help when trying to acting like a grown-up, but Komari never succeeds. But Komari never admits that she can't seem to act grown-up.

Don't you dare to underestimate her!

Hotaru is full of curiosity and interested in the village's life. She also has a crush/obsession on Komari Koshigaya due to Komari's petite appearance. Hotaru has a mature and "older sister" type of personality who is quite responsible and many of the characters often count on her, though she freaks out easily. However, when at home, she becomes really childish, especially around her mother, but people think she's just being modest when she says that.

A transfer student from Tokyo

Konomi is an 18 year-old girl and Natsumi's and Komari's friend who lives next door and attends the "local" high school as a twelf year student. She's a former student of the Asahigaoka Branch School. 

Konomi is a very caring and fun woman, but she can also be serious sometimes where she is a very mature that she acts as a role model for Komari Koshigaya and Natsumi Koshigaya as well as Renge Miyauchi.

Don't you dare to make her angry... 

One of the kids living in Asahigaoka, Renge is one of the most unique and mysterious, she is considered to be precocious child with a tomboyish side. She has a curious nature and a unique naming sense.

She gets excellent grades in school and has demonstrated excellent artistic skills. She even picked up multiplication solely based on Konomi Fujimiya's suggestion to use addition as a base for multiplying. She is shown to be friendly and affectionate and loves being around people. Never smiles. 

Nyanpasu! 

A tenth year grader and a high school student in Tokyo, where she entered to study after graduating from Asahigaoka Branch School. The middle of the three Miyauchi sisters. Despite the fact that Hikage studies in Tokyo, she often comes home and spends time with Renge and her friends. She is very proud of the fact that she lives in the city and reminds others of this at every opportunity, although she has not managed to get rid of her country manners. 

SHINKANSEN!!! 

Natsumi Koshigaya is a seventh-grader and 13 years old. Natsumi is a fun-loving girl who makes most of the fun ideas for everyone and she tried to get out of trouble or responsibility by blaming it on others (even objects) and hiding proof of bad things she did. She is very energetic as she can't sit still for long, often fidgeting in her chair. She often teased Komari Koshigaya (Natsumi's older sister) and Yukiko Koshigaya (Natsumi's mother) disapproves of her grades or messes.

The youngest of the Koshigaya siblings.

You are a kid, who grew up in a large city and moved to a laid-back country village Asahigaoka. There you join the local school where is only five students who are in the only class and meet four girls - Hotaru, Renge, Komari and Natsumi. This is story about your new village life! Have fun!
