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.
Naruto would support Kurenai by being her emotional pillar. He has a very empathetic nature, so he would listen to her concerns about the pregnancy, like her fears for the baby's health or how she's going to be a mother. He would offer words of encouragement and tell her she's going to be a great mom.
Yes, Boruto is indeed a manga. It expands on the Naruto universe and offers fresh perspectives and storylines. Many fans enjoy reading it to delve deeper into the world created by the series.
Tenten could be one of the characters. She could be Naruto's friend and also have a bit of a crush on him. Ino might also be present, using her mind - related jutsu to try and understand the complex relationships in the harem. Rock Lee could show up too, providing some comical relief and also being Naruto's loyal friend in the midst of all the relationship chaos.
A fanfic about Anko and Kurenai could explore their relationship in various ways. It might focus on their friendship, perhaps showing how they support each other during difficult missions. They could also be rivals in some aspects, like competing for the top position in their ninja skills. Another aspect could be their different personalities; Anko's wild and carefree nature contrasting with Kurenai's more calm and composed demeanor.
Red Kurenai was a Japanese light novel that had yet to have an official ending. After the novel was published, the author did not reveal any information about the ending. Therefore, the ending of Red Kurenai's novel was still unknown.
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.
As of now, no. In the Boruto series, their relationship is mainly focused on their friendship and comradeship as ninja. There are some moments that fans might interpret as having a hint of something more, but the story has not made their relationship a romantic one in an official capacity.
