Grandpa and Grandma Turn Young Again

Grandma is a nasty and maipulative thing most of the time, cousing endless trouble for her son-in-law and daughter, her grandchildren, and her neighbours.

There are far worse things than having to deal with your ex-boyfriend's little sister or your older brother's ex-girlfriend. But that's something Karada Iokawa and Shoko Nogami have to learn the hard way when a magic wishing stone inexplicably grants Karada's wish to be older - and does it by stealing the years from Shoko! Now Shoko, who's already graduated and studied overseas, is Karada's age, just about to enter junior high school. Meanwhile Karada must suddenly face the real facts about what being grown up entails. And just to make a bizarre situation even more awkward, there's the issue of how to handle their existing romantic interests!

An unaired episode bundled with the home release of Ojisan to Marshmallow.

An old man well into his 60s makes the hearts of old ladies flutter with his handsome speech and charming behavior.
