Alternatively, the title might already be in use, so the user wants to verify that the animation is the real deal. Maybe they need a feature that distinguishes their official product from fan works or imitations.
Also, consider current trends in animation marketing. Verified content could mean something like official collaborations with verified partners, or verified cosplay. Maybe integrating with NFTs for verified collectibles.
Another thought: in Japan, there's a game called "Jinsei Seiyoku" or games where characters boost their stats. Maybe "Tsuyotsuyo" refers to being super strong. So the animation could be about a character or group with exceptional strength, and the "verified" aspect is part of their story or merchandise.
