I'm not familier with Uma-Musume. I asked Chat-GPT, Uma Musume has many characters, but the most popular is said to be "Special Week". Special Week is one of the main characters in games and anime, and is portrayed as a racehorse with a bright and energetic personality that everyone loves and top-notch speed.
Among us was very popular among children. Everyone becomes a crew (crew) and carries out missions such as repairing broken equipment in the spaceship, but impostors (werewolves) disguised as crew kill the crew one after another. Find the imposter before the crew is wiped out, but don't accidentally expel the crew.
