From wiki:
Jump Festa (ジャンプフェスタ,
Janpu Fesuta) is an annual party or exposition in Japan, all about anime and manga, sponsored by Shueisha, creators of the various
Jump anthologies. New movies, manga, games and merchandise are introduced during this event. The tradition is that of already existing material a special item or episode is produced and presented at the convention to prove the makers aren't out of ideas and to experiment. Manga-ka of popular current and former Jump series are often on hand, and many of them have panels where they answer questions.
The event also acts as a gaming convention most notably Namco Bandai and Square Enix which often debuts trailers and new gameplay footage as well as game demos for the public. Although the event is focused around Shonen Jump, there are often events for many other anime and video game franchises, as well.
Like the fact you can get characters to assist you in battle (Tifa x Cloud against Sephiroth, nice
)
