Osananajimi (Ritsu-chan) used "ZBOING! Puberty Upgrade" before reuniting with Gen ... IT'S SUPER-EFFECTIVE!
Oh, How Cute; when Ritsu announced she wanted to play "like adults", for a few seconds Gen.exe had stopped working (lol). And by the time *koff-koff" "adult playtime" is over, the next generation's Secret Base may have been desecrated by "cooties"; not sure whether there's a purification ritual that can help them there. And on page 24 (last panel):
Gen: "I thought I got away from any sort of Osananajimi Inquisition."
Old Folks (to jarring musical chord): "NO-ONE ESCAPES THE OSANANAJIMI INQUISITION!" (and quite possibly, Gen's mother has been told to prepare red rice and/or red beans ... say-no-more, say-no-more).
In The End, "Well Isn't That Cute? ... BUT IT'S RIGHT!"
Ooh, a Vanilla Osananajimi release.
Ah, the good old 'Friend you thought was a guy back then turned out to be a girl' storyline. Nice.
Great ending though! Ah...How fast the news spreads. But hey, at least everyone seems to be happy for them!
