Announced in 4th TV season's final episode

The 13th and final episode of the Utano☆Princesama Legend Star television anime ended with an announcement that the Uta no Prince-sama franchise has a new anime project launching.

Utano☆Princesama Legend Star was the fourth anime season adapting Broccoli's dating simulation video game for female players. In the first season of the slapstick romantic comedy, the female protagonist goes to a school for the performing arts with young men who are budding idols. The subsequent seasons followed seven of the young men after they form the idol group ST☆RISH.

The original Uta no Prince-sama - Maji Love 1000% anime aired in Japan in July 2011, and ended in the September of that year. Niconico streamed that series outside of Japan as it aired. Uta no Prince-sama - Maji Love 2000%, the second series, premiered in Japan in 2013, and Crunchyroll also streamed the series.

Sentai Filmworks has licensed the previous three seasons. Crunchyroll is streaming Utano☆Princesama Legend Star as it airs in Japan.
