The Quinx Squad could react with a mix of respect and wariness. They respect power, and Kaneki has a lot of it. However, they are also loyal to their cause of protecting humans from ghouls. Meeting Kaneki would force them to re - evaluate their views. They might start to question whether all ghouls are truly bad, especially when they see that Kaneki has his own moral code. This could create internal conflict within the squad as they try to figure out how to deal with Kaneki.
At first, Sans would probably be a bit shocked, but then he'd turn on his laid - back, sarcastic attitude. He might make jokes at Gaster's expense, which could either annoy Gaster or make him respect Sans more. If Gaster tries to harm him, Sans could use his shortcuts to dodge attacks and try to find a way to reverse the situation. He'd also likely be thinking about how this affects his friends in the Underground, especially Papyrus, and try to find a way back to them.
Harley Quinn might get really into it. She has a wild and unpredictable personality. She could start to role - play some of the scenarios from the fanfiction in real life, much to the confusion or amusement of the other Squad members. It would be in - character for her to embrace this strange new view of their world.
Papyrus might be initially shocked. He's used to Sans being more laid - back, so seeing him in a fight could be quite a surprise. His eyes would widen and he might gasp.
The ninja world would be in shock. The Hidden Villages would be very cautious around Naruto. They might see him as an even greater threat or an unknown entity. His friends, like Sakura and Sasuke, would have to adjust to this new Naruto and learn how to fight alongside him with his new powers.
Bakugo would likely be furious. He'd feel betrayed and would probably be the first to attack Deku, yelling at him about how he's thrown away everything they've worked for. Uraraka might be more empathetic. She'd try to understand what drove Deku to become a villain and hope there's a way to bring him back to the side of good.
In Comic Sans, 'Sans' typically refers to the style of the font being sans-serif, meaning it doesn't have the small decorative lines at the ends of the strokes.
