New "Monogatari" Anime Adaptations might be in the works judging from a recent billboard ad in Japan.
For several days a billboard at Ikebukuro Station by Aniplex/Shaft/Kodansha has been displaying a timeline of all Monogatari Anime Series however there are two suspiciously empty spaces left after 2024. Space for two titles.
The only series missing on this ad are "Off-Season" & "Monster Season". Given that Aniplex is currently teasing two Anime Projects codenamed "O" and "M" japanese fans are now speculating that this is about new Monogatari Anime.
The Official Reveal will be later today/tomorrow.
