Meanwhile, Sugihara and Takeuchi are playing in the park with Yaeka and then Yaeka becomes friends with a little foreign girl named Sara. The next day, the new neighbors to the Sakuragi household come to visit and... Now that Yaeka's birthday is here, what could the dish that Kirishima prepared for Yaeka be?

Masaya has a vendetta against Kirishima, if only Kirishima can remember who he is.
