Demon Slayer will never surpass One Piece or anyone in the Big 3. It hasn't influenced anything like One Piece, Bleach and Naruto have. In a month or two the hype will die down and sales will diminish as they have in the past. Not to hate but I just think it's dumb to say it's "Surpassing One Piece " when it's absolutely not. You can still like and love Demon Slayer, just don't compare it to anyone in the Big 3.
