If we assume 'in live' means 'involved', Naruto can be involved with fanfiction through the creativity of fans. Fans write stories about him, so he becomes part of the fan - created fictional scenarios.
There's also 'Date A Live: Ninja Invasion'. This fanfic has a really cool concept where the ninjas from Naruto start to show up in the Date A Live world, causing chaos and also creating some unexpected alliances. It's full of action and some really fun character interactions.
It could mean that Naruto, the character from the Naruto series, is somehow involved or associated with fan - created fictional works in an interesting way. Maybe it implies that there are fanfictions that are very much centered around Naruto's character and his storylines.
One interesting aspect could be the exploration of Naruto's character in extreme situations. It might show how he overcomes his darkest moments and finds new reasons to keep going. For example, it could depict him facing an enemy far stronger than he's ever encountered and having to dig deep into his willpower.
There may be new characters introduced as well. Maybe a mysterious figure who has a special ability to either enhance or dampen Naruto's will to live. This character could add an extra layer of mystery and conflict to the fanfiction.
One interesting concept could be the idea of characters getting a second chance at life. For example, a character who died in the original Naruto series might be brought back in the fanfiction with new abilities or a different perspective on life. Another concept could be the exploration of alternate timelines where events in Naruto happened differently, leading to new and exciting storylines.
Sasuke. He has such a complex character arc and his death would have a huge impact on the story. So, in fanfiction, he's a likely candidate to come back to life and continue his journey. Maybe he has some unfinished business or a new purpose to fulfill.
In a 'Naruto in Date A Live' fanfiction, Naruto could be a key figure in preventing a total war between the Spirits and humans. His ability to understand and empathize with outcasts (like he did with Gaara) could help him communicate with the Spirits on a deeper level. He could teach Shido some of his ninja techniques to better protect the Spirits and also use his own chakra to help stabilize the space - quakes caused by the Spirits, thus bringing a new hope for peace in the Date A Live world.
In the 'naruto has no will to live fanfic', it might explore Naruto's extreme state of mind. Maybe he has faced so many traumas and difficulties that he loses the will to live. For example, he could have witnessed the death of too many loved ones, like Jiraiya, and felt overwhelmed by the responsibilities on his shoulders.
They probably handle conflicts by talking it out. Naruto is not one to hold back his feelings, and Ino is also quite outspoken. So they'd likely just blurt out what's on their minds and then find a middle ground. For example, if Naruto wants to go on a dangerous mission and Ino is worried, they'll argue at first but then come to an agreement that he'll take extra precautions.
