Yone

 is one of the Downtown's advisors. They asked Tsugumi, who was the Downtown's youth representative, to hold a live show to attract young people to their "Healthy GoGo Festival". Though Tsugumi calls them elders, they are energetic enough to go and enjoy the Joint Cultural Festival, as well as Poppin'Party's self-hosted concert. However, in the 8th episode of BanG Dream 3rd season, just before the Downtown's excursion, all three suffered a strained back and unable to get up. Since their contract with their excursion's venue has no cancellation option, they offered it to Tsugumi and asked her to gather the number of people and go instead.
