Amuse, Animate, and bilibili are working together on this show. It'll take place physically at the Makuhara Messe Event Hall in Japan. The list of performers includes GRANRODEO (Kuroko no Basket), Liella! (Love Live! Superstar!!), Liyuu (Love Live! Superstar!!), Maaya Uchida (Idolm@ster), May'n (Macross Frontier), Miyu Tomita (Date a Live), Yuma Uchida (Kono Oto Tomare!), Umamusume, STATION IDOL LATCH, and TM Revolution (Gundam Seed Destiny). Quite the star-studded list.
For those of you who are currently stuck outside of Japan, like myself, there will thankfully be a stream available worldwide. This is a one-time stream and will not be played again. There will be no archive so I hope you're a night owl. The start time is set for 5PM JST/1AM PST/4AM EST.
Cost is 3300 JPY which is, at press time, about $24. Take advantage of that exchange rate, folks!
Tickets are available here.
