Now, as they return three years later to perform at Anisong World Matsuri at Anime Expo 2017, the members of Wake Up, Girls! (also known as WUG in short) are no longer rookies.
When the seiyuu unit Wake Up, Girls! first visited the United States in 2014, the seven-person idol group had just finished the broadcast run of their debut anime series in Japan.
They were gaining popularity among fans around the world, but their activities were still limited as rookie performers.
