On March 5th, a mysterious advertisement reminiscent of the appearance of "Shocker" appeared inside the east ticket gates of JR Shinjuku Station in Tokyo. The advertisement suggests that a "mysterious" announcement will be made on March 7th, and that Shocker will attack "AnimeJapan 2025", one of the world's largest anime events, to be held at Tokyo Big Sight (Koto-ku, Tokyo) on March 23rd.
On the same day, a mysterious website was also launched. Further information will be announced at a later date. The mysterious advertisements will be up until March 9th.
