Summary
Riri's birthday is coming up and Yuyu hopes to get her favorite drink a ramune for her birthday.

Plot
While resting outside of the school, a calico cat rests on Mai's chest and Tazusa approaches her detailing her misfortune trying to befriend it. So, Mai advises her to try now as it rests on her chest and as Tazusa does, the cat swats its paw at her.

In her dorm, Yuyu reflects on what she should do to show appreciation to someone, which amuses her roommate Matsuri. Elsewhere, Riri, Kaede, Fumi set up a small table to recruit the final two members to their Legion. Upon seeing Mai and Tazusa the trio approach them to ask to join their Legion, however, they refuse. Someplace else, Moyu talks with Miriam about Moyu's problems. Meanwhile, Yuyu, Riri, and Kaede enjoy tea together and Fumi joins them to show off a tablet that reveals personal information on Riri. From it, it's learned that Riri's birthday is the following day, and she later asks Moyu for advice on what to give Riri for her birthday. However, her idea for a present is too grotesque, so Yuyu then asks Miriam, who suggests giving her a ramune, which is her favorite. On the other hand, Miriam also states that anything Yuya would give Riri would be greatly appreciated. To corroborate the fact, Yuyu visits Shenlin and Yujia who confirm that Riri likes ramune. Tazusa also confirms that Riri likes Ramune as she feeds a stray cat. Eventually, Yuyu visits the school store where she buys some ramune candy and bumps into Mai there too. Later outside with some ramune candy, Yuyu is approached by Shiori who offers to help her wrap her present for Riri, but she declines. So Shiori instead gives her some pointers on how to wrap instead. Following, Shiori's advice, Yuyu manages successfully wrap her present. The following day, Yuyu visits Riri's old hometown that the Huge attacked. There she buys and tries a ramune and talks with the shop keeper there. Before leaving, she buys another ramune just for Riri.

Meanwhile, Mai and Tazusa talk about why Tazusa doesn't want to join a Legion. On a train ride home, Yuyu heads back to the academy, but as she gets off the train, she encounters a young girl begging her father for a drink and Yuyu gives the girl her ramune. Eventually, Yuyu runs into Mai and Tazusa who were "cat hunting" and as they head back to the academy, they find a vending machine covered in vines that dispenses ramune. This sudden revelation leaves Yuyu distraught.

At the academy, the members of the Legion along with Mai and Tazusa are present for when Yuyu gives Riri her birthday presents. Requesting for one more thing; Riri asks Yuyu to be "hers" which is basically just asking for a hug and Yuyu obliges, in turn, giving Riri a bear hug. After this, both Mai and Tazusa agree to join Riri's Legion, making it an official Legion. Later that night, Matsuri reveals to Yuyu the name of Riri's Rare Skill, "Charisma".
