Sure, Kakashi is present in the Boruto manga. His role might not be as prominent as in the Naruto series, but he still has significant moments and interactions.
Kakashi is very much alive in the Boruto manga. The manga doesn't include his death. Maybe you got some misinformation or confused it with another character's fate. But for sure, Kakashi is around.
Another interesting point in Naruto bell test fanfiction is the inclusion of alternate scenarios. What if Naruto had managed to steal the bells without Sasuke or Sakura's help? Fanfic writers can create unique storylines based on these 'what - if' situations, which can add a fresh perspective to the original bell test concept.
It's appealing because it gives a chance to rewrite or expand on the events. Writers can introduce new elements, like different jutsu or unexpected alliances. For instance, a fanfic could have Naruto form an alliance with a minor character during the bell test.
Well, Naruto could figure it out by thinking outside the box. He's not one to follow the normal rules. So, instead of directly trying to take the bells from Kakashi in a traditional way, he might come up with a plan like using distractions. Maybe he creates a diversion with his shadow clones while Sakura and Sasuke sneak up on Kakashi from different angles. This way, they work together and have a better chance of getting the bells.
In some fanfictions, Naruto might figure out the bell test by using his unwavering determination. He realizes that the test is not just about physical strength but also about teamwork. So he tries to convince his teammates to work together, seeing through the real intention of Kakashi Sensei behind the test.
In a Naruto bell test solo team fanfiction, a character might use unique jutsu to try and get the bells. For example, Naruto could use a new form of the Rasengan that he developed on his own. He might also form unexpected alliances with other characters during the test, even if it's a solo team concept. Maybe he teams up with an animal in the forest to outwit Kakashi in getting the bells.
