Demon Slayer Kimetsu no Yaiba is an incredibly popular manga by Koyoharu Gotoge, and the anime adaptation by Ufotable only made it even bigger. Kimetsu no Yaiba became one of the best selling manga of all time with over 40.3 million copies in circulation. While the manga ended this year, running from February 2016 to May 2020, its popularity is still ongoing. Most notably with a new movie by Ufotable.

CyberConnect2, makers of the popular Naruto Narutimate series, are currently developing a Kimetsu no Yaiba PS4 game. It's really promising and should be a way higher quality than a lot of the 3d battler arena every popular shonen gets nowadays.

Granblue Fantasy will hold the yearly Granblue Fantasy Fes event in December 11-13; We will have some announcements regarding Granblue Fantasy Relink then. Previously, Producer Yuito Kimura and Director Tetsuya Fukuhara stated the game's development is going well, but it won't receive a release date until the very last moment.

There's also the fighting game Granblue Fantasy Versus out now on PS4 and PC. Though it looks pretty dead online. At least outside Japan.
