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.
Ino would be worried sick about Naruto. She'd probably feel a sense of responsibility, especially if she thinks she could have prevented it. She would use her in - depth knowledge of Naruto's mind, which she has gained from their interactions over the years. Ino would try different mental techniques, like creating mental images of their friends and happy memories in Naruto's mind to counter the negative effects of the hypnosis. She would also be on high alert for any signs of danger to Naruto while he is in this vulnerable state.
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.
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.
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.
Often, Ino is initially shocked. After all, Naruto might not be the person she expected to ask her out. But then she might show her kind side and accept. For example, she could blush a little and say yes with a shy smile.
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.
One possible plot could be that Naruto is hypnotized by an enemy ninja who wants to use him against the Hidden Leaf. Ino, being a skilled mind - user herself, tries to break the hypnosis. She has to first understand the nature of the hypnosis, which might be a complex jutsu. Then she dives into Naruto's mind, where she encounters various manifestations of Naruto's fears and desires. Ino has to navigate through these to reach the core of his mind and free him from the hypnosis.
At first, it would be a really shaky and awkward relationship. Naruto's flirting might be a bit too forward for Ino, so she would be hesitant. But as time goes on, if Naruto shows his genuine feelings through his flirting, Ino might start to see him in a new light. For example, when Naruto flirts by sharing his dreams with her, like how he wants to be a great Hokage and make the village a better place for her, Ino might start to respect him more and be more open to his advances.
It could develop into a really good friendship. They'd learn more about each other's quirks and habits.
