I have a feeling you're making a joke, but I'll answer seriously just in case: just like anything else, it's only sinful if it actively promotes sin and the degree to which its sinful is directly proportional to how much sin it promotes. Also if it becomes an idol that replaces true worship of God.
So not in general no. Anime by itself is licit according to the Magisterium, but if it facilitates sin or you make it an idol, yes.
