EPISODE 19 "Magic Picture Diary"

"There are things... I want to do with my mom".
To grant Umi's wish, Hairi and Shiroha form a "pretend family" with her. They build a water slider in the pool for Umi, sing songs with Tsumugi, and create a picture book with Kamome's help. Hairi, Shiroha, and Umi spend their time together, laughing like a real family. Shiroha happily says, "I hope I'm being a good mom". However, after witnessing Umi say things that seem to predict the future, Shiroha suddenly declares that she quits being a mother.
