Yoko's get-together with the demis comes to a conclusion, but will the world still be intact for the after party? Then, love is in the air as Takahashi-sensei gets ready for a date with Sakie-sensei, but that won't stop him from taking a detour into the evolutionary history of demis! He's got more than just Sakie-sensei on his mind, though, now that Kyoko has confessed that she has a crush on him. How should he let her down easy? Finally, the girls gather to watch the fireworks to close out the summer, and they learn a little bit more about Kyoko in the process. Not every revelation has to be huge–some are just enough to warm the heart!
