One of the main themes is reincarnation. The story revolves around a man who is reborn in a different world, which leads to exploration of new identities and second chances at life.
Eris Boreas Greyrat is also captivating. She is a strong - willed character. Her relationship with Rudeus, from being his student to something more, is full of development. Her hot - tempered nature and her growth as a swordsman add depth to her character.
If a character has the Rinnegan and Shinra Tensei, their personality could be shaped by the fear and respect they receive from others. For example, if they are initially shy but gain this power, they might become more confident or even a bit arrogant. The power could also make them more responsible as they realize the impact of their actions.
I think Makarov would be an interesting character to revive with Edo Tensei in a fanfiction. He was such a powerful and respected guild master. His revival could bring back his leadership and wisdom to the Fairy Tail guild. Also, he had a deep connection with all the members, and his return could strengthen the guild both morally and in terms of combat capabilities.
He might become more aggressive. The process of Edo Tensei could taint his positive nature. Instead of his usual friendly self, he could be more focused on the task given by the caster of the jutsu, which may be to cause destruction.
Her character could also grow in the fanfiction by interacting with other characters from Naruto's generation. She might be surprised at how far the ninja world has come and could offer her unique perspective on things, which in turn shapes her character further.
Well, an unexpected pairing could be Itachi and Luffy from One Piece. Itachi's calm and calculated nature would contrast greatly with Luffy's carefree and impulsive personality. It would be interesting to see how they interact, especially since Itachi has his Sharingan and Luffy has his Gum - Gum powers.
Hard to say. It could be on hiatus, but without concrete information, it's difficult to give a definite answer. Try following the mangaka's social media or the manga's official website for the latest.
