I'm not entirely sure as I haven't read it specifically. It could be about a dark or mysterious story, perhaps involving death (since'morte' means death in some languages) and presented in a graphic novel format with unique art and characters.
I don't know the main characters in 'Morte Graphic Novel' as I haven't read it. But they could be characters related to the theme of death. Maybe a reaper - like figure or someone on a journey to understand death.
Maki in fanfiction usually has a fierce loyalty to her friends, especially Yuta. She is the type to fight for what she believes in. Yuta is sometimes portrayed as being a bit naive in the ways of the world outside his own small circle, but his pure heart makes him endearing. In many stories, their different personalities create an interesting dynamic, like in a story where Maki's boldness gets them into a risky situation and Yuta's calm thinking gets them out.
Well, one way this could work in a fanfiction is that Naruto could use Yuta's powers to enhance his combat abilities. Yuta has some really unique and powerful cursed energy techniques. Naruto might be able to combine his chakra with Yuta's powers, like using the Rasengan with Yuta's cursed energy for a super - powered attack. It could make for some really interesting battles against tough opponents like Madara or Kaguya.
