Regarding the 'choes and dealth' in Akame ga Kill Naruto fanfic, it could be that the 'choes' are the remnants of the different values and powers from both universes. These could be in conflict and result in death. The Naruto characters' belief in friendship and perseverance might clash with the cut - throat nature of Akame ga Kill. This conflict could cause a lot of death and destruction. It could also be a way to explore how different cultures and power systems interact when merged in a fanfic.
In some fanfictions, a crossover might involve the Akame ga Kill characters joining Naruto in his fight against the Akatsuki. Akame's Murasame could be a formidable weapon against the likes of Sasori or Hidan. And imagine Tatsumi learning chakra control from Naruto. It would be a cool way to blend the two universes. Also, the different power systems interacting, like the Teigu in Akame ga Kill and the kekkei genkai in Naruto, could lead to some really creative plotlines.
One idea could be a crossover where Naruto and Sasuke are somehow transported to the world of Akame ga Kill. They could team up with Akame and the Night Raid members to fight against the corrupt empire in that world. Maybe Naruto uses his shadow clones to gather intelligence, while Sasuke's sharingan helps in combat against the powerful foes.
The 'choes' could be represented as the memories or legacies of the characters. For instance, the echoes of Naruto's determination to become Hokage could inspire some Akame ga Kill characters to strive for a better world in a different way. Or the echoes of Akame's past assassinations could haunt the Naruto characters, making them more aware of the darkness that can exist in a world.
One interesting Naruto and Akame ga Kill harem fanfiction is 'Naruto in the World of Akame ga Kill'. In this story, Naruto's skills and personality are blended into the Akame ga Kill universe, leading to some unique interactions with the female characters from both series. It has an engaging plot that keeps you reading as he tries to navigate this new and dangerous world while also dealing with the growing harem around him.
The combination of two very different universes like Naruto and Akame ga Kill makes it appealing. Naruto's world has ninjas and chakra, while Akame ga Kill has a more dark and political setting. When you throw in the harem aspect, it adds an interesting dynamic of relationships. The different personalities of the characters from both series interacting in a new context is really exciting for fans.
Sasuke and Esdeath could be a fascinating pairing. Both are extremely powerful and have a certain ruthlessness. However, Sasuke has his own moral code which would clash with Esdeath's more extreme views. This conflict could drive an intense story.
