Naruto would be devastated. He might blame himself for not being able to protect his son. Sasuke would be angry and would likely go on a hunt for the perpetrator. His friends like Sarada and Mitsuki would be heartbroken. Sarada might vow to become stronger to prevent such a tragedy from happening again.
After Kurama's death, Naruto faced new challenges. His chakra reserves were reduced, but he continued to guide and inspire the younger generation of ninjas. He also had to adapt his fighting strategies without Kurama's immense power.
No, Boruto is alive in the manga. The plot hasn't led to his death. However, the manga is ongoing, and anything could happen in the later developments.
For Boruto, he could develop from being a bit overconfident to a more mature and reliable ninja. Maybe through his interactions with Sumire, he learns to think more before acting. For Sumire, she could become more assertive. Working with Boruto, she might find the courage to voice her opinions more often and take on more leadership roles.
It could also mean that a major chapter in Boruto's life has ended. Maybe a big battle or a long - running conflict has been resolved, and this is the end of that particular part of the story. However, it doesn't mean the whole series is over. There could be spin - offs or new storylines that start from this 'end'. For instance, a new generation of ninjas could be introduced who are inspired by Boruto's story so far.
The ending of the Boruto manga is a combination of emotional moments and big reveals. Different characters have their destinies fulfilled in unexpected ways. It's a finale that will leave you thinking, but I suggest you discover it firsthand by reading it.
In the Boruto manga, we see Boruto and his friends facing various challenges and mysteries. There are intense battles, unexpected alliances, and revelations about the ninja world's past and future.
