Not sure what the drama was aside from Musashi and Kojiro playing old people.
After the Isshu motto (with the correct music finally!) Musashi picks up where she left off last week and wants ice cream. Luckily, they received a package from QQ full of freeze dried food, including ice cream! The first half of the episode is just them eating.
When they get back they finally talked to their guest, Mijumaru's voice actress. Mijumaru comes out near the end and Musashi brings up Meloetta. Misato Fukuen requests they play "Best Wishes", so the show wraps up with that song playing in the background as the TRio remind us of the Rocket episodes airing on Kids Station next month.
