Naruto is often full of surprises. He might first act all nonchalant and say it's just a new thing he's trying. But when he sees Anko's serious face, he would start to panic a bit. He could try to make a joke out of it, like 'Hey, Anko - san, this fanfiction - drink is supposed to make me write better ninja stories!'. In the end, if Anko doesn't buy his story, he would probably just bow his head and admit it was a stupid idea.
If Anko catches Naruto 'drinking' fanfiction, Naruto's reaction would be quite complex. He's a bit of a daredevil and often does things without thinking. So initially, he might be defensive, saying he heard from someone that fanfiction has some magical properties when 'consumed'. But as Anko stares him down, he'll realize how silly it sounds. He might then turn into his more sincere self and say he was just curious and didn't really understand what fanfiction was. He would likely promise Anko not to do such a strange thing again and might even ask her to explain what fanfiction really is so he doesn't make the same mistake in the future.
She might be really confused. Fanfiction isn't something you can actually drink, so she'd probably think Naruto has lost his mind and scold him for doing something so strange.
Naruto would probably be extremely hurt at first. He values friendship and loyalty a great deal, so Anko's betrayal would be a huge blow. But he wouldn't give up. He'd likely try to talk to Anko to find out why she did it, hoping to change her mind.
Naruto might be a bit shocked at first, seeing the usually tough Anko in a vulnerable, drunk state. He would probably try to help her, like getting her some water or finding a place for her to rest.
Anko might initially be very angry. She has a prideful nature, so being humiliated by Naruto would make her want to lash out. She could challenge Naruto to a rematch immediately, vowing to make him pay for making her look bad.
Naruto would probably be very kind and protective. He knows what it's like to be alone as a child, so he'd do his best to make the child feel safe and loved.
If Naruto does figure it out, he could be really flattered. He might see Anko in a whole new light. But he would also be a bit confused because he has always seen her more as a senior or a friend. He would probably try to handle the situation gently, not wanting to hurt her feelings.
He'd probably be shocked. I mean, a tank is so out of place in the Naruto world. He might be scared too, not knowing what this huge, metal thing can do.
At first, Naruto might be a bit cautious. He's used to facing opponents in battle, and a strange new object like a robot could potentially be dangerous. But once he realizes it's not an immediate threat, he'd likely approach it with his usual enthusiasm. He might start asking it all sorts of questions, like 'What are you?' and 'Where are you from?' His reaction would be a mix of excitement and wariness.
Naruto's reaction would be a mix of curiosity and caution. He would be curious to explore the contents of the Bingo Book, looking at the profiles of different ninjas. However, he would also be cautious because he knows that having this book could make him a target. He might also feel a sense of responsibility, thinking that he has to protect the information in the book from falling into the wrong hands. He may even try to find out how the Bingo Book is updated and who is in charge of it, so that he can understand the system better and use it more effectively.
Naruto would most likely see the wolf as a new comrade. He has a strong sense of justice and would feel responsible for protecting the wolf. He would introduce the wolf to his friends like Sasuke and Sakura. They could all train together, with Naruto showing off his Rasengan and the wolf showing off its natural hunting skills. And Naruto would always be there to make sure the wolf is safe and happy in the ninja world.
