At school she enjoys studying and playing with many friends, including her close buddy Tama‑chan, the student‑committee members Maruo‑kun and Migiwa‑san, and the B‑class trio of ‘little master’ Hanawa‑kun, Hamaji‑Bu Taro, and Sekiguchi‑kun. This cheerful series captures the simple joys of everyday life.
