Yuzu's mom finally shows up and we hear from her.. She's been looking in at the kindergarten Yuzu's at all day and the teachers had been getting suspicious so they sent Kippei to take a look. Kippei realizes that she's Yuzu's mother and asks her why she doesn't take care of Yuzu.. Her husband died and it seems like she did something bad to Yuzu once and now she's scared that she can't take care of her now. But, someday, when she's ready she'll come back.. She asks Kippei to not tell anyone, not even Yuzu, that she's been there. However, Kippei runs with Yuzu to the train tracks when he picks her up and they see Yuzu's mom on the train (in super-duper dramatic slow mo)...

Yuzu doesn't really say anything about it, though. It must be tough to finally see her mother after so long and not be able to talk to her or anything.. It'll be hard on Kippei when the time finally comes for Yuzu to be back with her mom. You can really see how much he cares for her. We'll see..
