Recap of the first seven episodes of 91 Days series.

Atsuko "Akko-chan" Kagami (known variously as "Stilly," "Caroline," or "Julie" in Western versions of the anime) is an energetic elementary school girl who has an affinity for mirrors. One day, her favorite mirror which was given to Akko by her mother (or in some versions, by her father, as a present from India) is broken, and she prefers to bury it in her yard rather than throw it to the trash can. In her dreams, she is contacted by a spirit (or in some cases the Queen of the Mirror Kingdom) who is moved that the little girl would treat the mirror so respectfully and not simply throw it away. Akko-chan is then given the gift of a magical mirror and taught an enchantment that will allow her to transform into anything she wishes.

Rifle-shooting sports are competitive activities testing accuracy and precision using a rifle. In Japan, carrying firearms is prohibited, so most of the participants are members of the defense force. When the use of rifles using a light beam instead of real bullets as ammunition became common, rifle-shooting competitions became accessible to the younger population, giving way to school contests. First-year high school student and marksmanship enthusiast Hikari Kokura has just transferred to Chidori High School. She tries to join the club of her choice, but finds out that the club no longer exists due to the low popularity of the sport. Distraught, she tries to restore the club and somehow manages to recruit three other members: her childhood friend Izumi Shibusawa, the half-Russian Erika Meinohama, and the stoic Yukio Igarashi. This marks the beginning of the Chidori Rifle-Shooting Club, who have only one goal—to compete on the national stage! [Written by MAL Rewrite]
