Hina-chan… There is something that Sora-neetan wanted to tell you that mommy and daddy will not come back!
*cries*
Yup, Sora finally said to Hina-chan that their parents will not come back and see Hina’s performance at Parents’ Day!
Even Miu is crying because Yuri and Shingo are already dead… or is it? But we’ll never know!
Although both Aunt Yoshiko and Uncle Nobuyoshi finally accepts Yuuta’s role as the acting father to the three girls, it seems that only problem he has to face…
…is how to make Hina-chan happy again? Wow, that’s gonna be a tough cookie!
Then, how about making Raika-san her mommy…
…and so were these guys. They want to be Hina’s daddy!
Yup, that will cheer her good! Good job, Yuuta!
So anyway, all is well that ends well in PapaKiki!
Good thing Aunt Yoshiko and Uncle Nobuyoshi were here to watch Hina sing…
Twinkle, Twinkle, Little Star~! How I wonder what you are~!
Uh, I’ll pretend that I’m the one singing in an obnoxious voice instead of Hina-chan doing it along with the other kids.
Even though I didn’t find a clue whether Yuri and Shingo are actually dead, but what counts is how Yuuta cared so much on the three girls!
Still, there is some more materials for another season. But for now, this is the happy end for PapaKiki!
