Girl's High

With their dream of entering an all-girls high school approaching, Eriko, Yuma, and Ayano decide to explore the school during spring break. There, they encounter the harsh reality of all-girls high school. There, they encounter Koda, Himeji, and Ogawa, who are all current students. Koda and the others mistake Eriko and the others, who are wearing high school uniforms, for seniors. Unable to back down, Eriko makes up stories about "high school life at Saki Girls' High School"...

Eriko and Yuma are relaxed about their first physical examination since enrolling at Sakijo High School, while Ayano is a bit delusional. However, when Koda and the others tell them about the physical examination at a girls' high school, they are told that they are required to wear only panties and a cape! What's more, they are asked to go around each examination venue in these attire for an "in-school orienteering"! Eriko, feeling down, proposes a competition to see who can go around the whole thing the fastest, but...

The Idiots, jealous of the fact that Himeji has a boyfriend, have Himeji set up a mixer. On the day of the mixer, the guys are taken aback by Eriko and the others' high spirits and just smile politely. However, Ayano and the guy Shimotakaya, who are both interested in each other, enter their own world. With Eriko and the others dumbfounded, the two believe it's fate and start dating...

It's Yamasaki Girls' Private School Sports Festival. Eriko and the other six get excited after Odagiri promises to buy them ice cream if they win. Then, things heat up even more with the arrival of Saionji, Koda's rival. They do very well in the events they participate in, including the ball tossing contest. Despite losing by a narrow margin to the Red Team, Eriko and the others aim to make a comeback in the second half, but...

On her way to school, Eriko is captivated by a beautiful, idol-like girl who picks up her dropped handkerchief. That day's swimming lesson is held at the nearby Shimomura Junior High School pool, as the swimming pool is out of order. After the lesson ends safely, as Eriko and her friends are about to return to Sakijo, a student from Shimomura Junior High approaches them. It is the beautiful girl Eriko met that morning...!

Suspected by Ayano of spreading false rumors and trying to ruin her relationship with Shimotakaya, Yuma rushes out of the classroom and calls her sister Momoka. After school, the Idiots meet Momoka again. However, only Eriko sees through Momoka's lie and believes Yuma. Hearing this, the Idiots rush out of the store and head to Yuma to apologize. Eriko is still worried about Momoka...
