Daikichi and Rin deliver food to Hitani as she recovers from a bug. While wrestling with her first loose teeth, Rin and the three other kids work on their jump rope, while Daikichi mingles with Hitani and the dads. After about a year with Rin, he’s watched her grow and they’ve shared countless experiences, a lot of them cause him stress and nervousness, but he seems to be learning that comes with the job.
Daikichi’s little sister Kazumi is getting married, but isn’t so hot about having a kid soon. She likes going out and drinking and having time for herself. Daikichi used to own all of his time, too, and while it’s obvious he’s lost something in his change of lifestyle for young Rin’s sake, he’s gained a lot more. This person loves him unconditionally, and he her. He may not be a real dad, and it may have just been a year, but he’s definitely become quite good at taking care of RIn.
What has more or less been a slice-of-life series has a reserved send-off, which looks back on the development of Daikichi and Rin, and looks toward the future as she grows bigger, stronger, and brighter. Rin has definitely been one of my favorite characters this season, and one of the better-acted kids I’ve seen in anime. There’s nothing earth-shattering about this story, but that’s not the point: it’s done a good job portraying the everyday and mundane, with all the little childhood firsts sprinkled in. And certainly the only anime I can think of where a guy’s aunt is so much younger than him, he could easily be her father.
