Naruto would be extremely worried. He would likely call on all his training and skills. He might start by retracing Ino's last steps. He would also be thinking about all the times Ino has been there for him and the village, which would fuel his determination to rescue her. He would be so focused on finding her that he would hardly rest until she was safe.
Naruto would be in a state of high alert. He would quickly assemble his friends and form a rescue team. He would be the driving force behind the mission, constantly motivating everyone. He might also have flashbacks of their time together in the village, which would strengthen his resolve. He would use his unique abilities, like his chakra control and his jutsus, to their fullest extent to find and save Ino from the bandits.
Ino would likely be very concerned. She might immediately try to use her mind - reading skills to figure out what has happened to Naruto. If she can't break the hypnosis right away, she'd probably seek help from her teammates or sensei. Ino is a determined character, so she won't give up easily on saving Naruto.
Well, one possible plot could be that Naruto and his friends immediately set out on a rescue mission. Naruto might use his shadow clone jutsu to search a large area quickly. Sasuke could use his sharingan to track the bandits. They would face various obstacles on the way, like traps set by the bandits. And when they find Ino, she could have used her mind - transfer jutsu to gather some information about the bandits' plans, which would help them in defeating the bandits and getting her back safely.
Naruto might react with shock at first. After all, his whiskers are a very distinct part of him. He could then start laughing it off as one of Ino's crazy antics. He might even joke about it and say something like 'Hey, Ino! Those whiskers are my trademark!'
She might be initially shocked. Ino is used to Naruto's regular abilities, and the sudden appearance of the Rinnegan would be a huge change. But then she would probably be curious and eager to learn more about how it affects Naruto and what new capabilities he has.
Ino might be initially shocked. But then she'd probably be quite excited. She could start planning all sorts of things to do with Naruto, like shopping for new clothes or teaching her about girl - only ninja techniques. Ino would likely see it as an opportunity to have a new kind of friend.
At first, Naruto would be stunned. But being Naruto, he'd quickly gather his wits. He'd probably joke around a bit to lighten the mood and try to get Hinata to open up. When he realizes she's serious, he'd start to analyze the situation. He'd think about what could have made Hinata do this and try to find a solution that would not only free him but also help Hinata if she's in some sort of trouble. He might also think about how this would affect their friends and the village as a whole.
Sakura would be extremely angry. She's Ino's friend and rival, and she would not tolerate Naruto doing such a thing. She'd probably be the first to go looking for Ino and confront Naruto. Sasuke, on the other hand, might be more calculating. He'd try to figure out Naruto's motives first before taking any action.
Sakura would be really happy for them. She has been friends with both Naruto and Ino for a long time. She would probably offer to help Ino during her pregnancy, using her medical skills. Shikamaru might act like he doesn't care much at first, but secretly he would be glad for his friends. He might offer some practical advice about raising a child, like how to deal with the financial aspects or the importance of education. Choji would be excited and would bring over lots of food to make sure Ino and the baby are well - nourished.
Naruto might be initially confused. He's used to people being friendly, but Yandere Ino's possessiveness would be new to him. He could try to talk to her to understand what's wrong. But if she gets too extreme, he would probably be a bit scared and try to distance himself.
Sasuke would be furious. He already has a strong sense of justice and loyalty to Naruto. He'd likely immediately start looking for Naruto, using his Sharingan to track any possible leads. He might even go against the village rules if he thought the village was involved in Naruto's kidnapping.
