They start by shopping for the small stuff first and they look for them and Haruno buys them. After shopping, Yu looks at those plastic bottles in the trash can, Haruno already got permission from an employee there. However, those bottles are different from the right size, but Kei only finds large plastic bottles and they look like her.

Umika hasn't used to take photos, while inside the photo booth, Yu and Haruno capture her to take it. Umika's photo is still fine and likes it, Yu wants to try the spring-only design and pose.

After the fun, they bought a bubble tea, Umika seemed to be her first time hanging out with them. Umika looks at a poster about robot anime that Matataki likes and hears in middle school. She asks them to think about the rocket design. Meanwhile, after they give her a large plastic bottle, Matataki is to make a rocket and doesn't need to waste her time on things. They will be the end of that and she'll put an end to the duel.

The next day, it's the showdown for the bottle rocket duel started and Yu introduced, Umika's feelings when they won. Matataki ignores Yu when she asks about her feelings about breakfast today. Matataki decided to get shown on the road, she asked Yu when she'd had breakfast ten days ago. They got two chances to launch their rockets and take the better record and Matataki evily talked her. The Rocket Two-Round Showdown has finally begun it starts Team Shooting Star, consisting of members of Umika, Yu, and Haruno. Matataki watches her while setting up a launchpad, but Haruno and Yu stare at her. Umika launches their plastic-bottle rocket and reaches 103 meters and it's the first record to farthest yet. Matataki launches her plastic bottle rocket and reaches 105 meters, thus beating Team Shooting Star.

In the second round, Yu squeezes the handle and they are ready to go, then their rocket launches and Umika lets those feelings reach Matataki, thus the rocket reaches 110 meters and they cheer for Umika. Matataki thinks when the rocket flew, her simulation was 107 meters in the longest flight distance. She brings a rocket, but it's not plastic, and activates it using a black powder engine, then her rocket launches. She calculates her rocket's flight distance to 127 meters, then it is her victory. Yu and Matataki fight themselves when Matataki cheats on her rocket, and Umika drops their plastic bottle rocket after they lose.

Umika finally calms Yu, Matataki bet Umika will ask her to help with her rocket. Umika asks Matataki if the goggles on her head are awesome, she has always seen her goggles since middle school and always wanted to tell her. She would love to try them on someday and since Matataki stopped coming to school and all, so Umika never got a chance to tell her. She would be happy if she got to see her at school again and feels frustrated about losing today. They will do it again and Umika dashes to get a drink. Yu feels like they forgot about their original goal and she picks up things and they'll meet again at school. They want drinks also, Matataki is exhausted and finally wears goggles.

The next day, Umika is trying to check Matataki's shoe locker, Yu thinks Matataki will be there today and uses her forehead to Umika, so it'll be fine. They arrived at the classroom and surprised her, Haruno noticed Matataki hadn't changed her outdoor shoes, but she already wiped them down and always forgot her indoor shoes. Umika seems happy about Matataki finally going to school and Matataki gives her goggles to Umika. She will play along with Umika for a bit until she will rack up enough attendance days.
