Video introduces two new "gum boyfriends" and a new storyline.
So you've got cute ramen boys to help you make dinner and cute onsen girls to help you relax, but what if you want fresh breath? Lotte's got you covered with the return of their "Gum Kare!" ad campaign, which anthropomorphizes their various brands of gum into handsome boys.
The fourth installment, titled "Time Leap School Trip" sees the story's heroine (a giant tooth) joining the boys for a class trip. Also coming along are Furuo and Tio Kajitsu, also known as the idol duo Geminica (who just happen to be our heroine's favorite idol unit). The "time leap" element and what Geminica are up to are anyone's guess, but new installments will be coming in future.
Furuo and Tio were created to parallel Lotte's Fruitio gum, which comes in multiple fruit flavors. They are voiced by Kaito Ishikawa and Ryota Ohsaka respectively.
