姉妹ちがい 米田和佐短編集

Mutsuki opens Kazusa Yoneda's one volume collection with the case of his older sister turning out to be a magic user, a story that runs across the first two chapters. Yayoi takes the third, a pair of twins split between a nurse's ward and the student council take the next two, and the last chapter backs up to Mutsuki and Haruki on their first day of high school. Six short comedies, no shared continuity.
