I caught the "he comes from a family of ninjas" line, but I am going to adamantly believe it was meant as a "haha get it, he moves like a ninja because he's a descendant of ninjas" type of thing. I really, really need this manga to stay on the rails, it's so close to being great that it's already the best football manga imo, and it's got that Kuroko no Basket vibe so I
know it could blow up and get wide appeal, meaning no sudden cancellation.
This could be really big, as in "animated by Production I.G" big. It just needs to stay on track, keep it grounded, and not start talking about "The Pinnacle of Perfection" like it's some kind of Ultra Instinct(I mean really, the secret to the power boost was just having fun? I'm dead).
Sidenote: Genuinely surprised we haven't gotten any talk or signs of a secret mystical state that will spread like wildfire once it gets introduced. So far, the manga has only had players "flaring up" or a specific character-based breakthrough, which is really refreshing honestly. Keep it about improving as players, and not a hunt for Ultra Instinct.
