Did you know that the truly popular Japanese anime rarely collaborate with other franchises? They might only do so once every few years or even a decade?

Have you ever seen anime like Pokémon, Demon Slayer: Kimetsu no Yaiba, Detective Conan, the Fate series, Gundam, Dragon Ball, One Piece, Naruto, and Evangelion frequently collaborate with other anime each year?

The answer is no. Truly popular anime have very stable sales, and they don't want to lose their consumer base to other anime through collaborations. Only less popular anime frequently collaborate with other anime.
