Yuko Natsuyoshi has been visible across anime and game projects in recent months. In August 2026, she voiced the girl in the Nintendo Switch release of Menhera-rium, a deck-building roguelite dice game. The Switch version launched on August 13 with a 20% discount sale, following the Steam version that has been available since February 18 and holds a "Very Positive" rating. Her role as the confined girl is central to the game's premise, where players must survive seven days by winning rounds of the dice game chonchiro.

Natsuyoshi also appeared in the music video for Wasurelanneyo's "Nannmonee," the opening theme of the TV anime Yani Neko. The video, released on August 13, features her alongside voice actor Tetsu Inada, director Taku Kimura, and original creator Nyan Nyan Factory, with cameos from the Kaiji series. This marks a crossover between the Yani Neko world and the Kaiji franchise, with which the band had previously worked.

Most recently, Twin Engine announced that stage greetings for the revival screenings of Super Kaguya-hime! will take place on September 20 at three theaters. Natsuyoshi will reunite with Anna Nagase, Saori Hayami, and director Seigo Yamashita for five shows, marking their first gathering since February. These engagements show Natsuyoshi's ongoing presence in both animated features and interactive media.
