Hana takes everyone to meet her grandmother, Tanpopo, who runs a traditional sweets shop. However, Tanpopo, agitated by complaints about her sweets declining in quality, ends up injuring her back. Hearing about a type of manjuu that Tanpopo used to make before her husband died, Hana and the others find his old recipe book and make some to cheer her up. When Gelos attacks with a Mou-Oshimaida, Tanpopo regains her strength to protect her shop, allowing the Cures to defeat it, after which she resumes selling the manjuu with some extra help.
