Sure, there is a manga for Death Parade. It expands on the story and characters presented in the original concept. The manga offers additional depth and details that fans might appreciate.
One idea could be exploring the backstories of the characters in more depth. For example, the arbiter's past lives before becoming an arbiter. Another could be creating an alternate ending to the series where different decisions are made during the death games. Maybe a fanfiction where the characters from different death games interact with each other outside of the normal game settings.
I have no clear idea. It could depend on the creator's plans or the popularity of the series. Try searching manga-specific websites or communities for accurate information.
It could be an evil shinobi from Naruto's world who has also ended up in the Death Parade world and is trying to corrupt the system. He wants to ensure that all the souls are sent to the void or something worse, just for his own amusement or power - hungry desires.
Perhaps Naruto enters the Death Parade world in search of a lost comrade. He teams up with the arbiters, reluctantly at first, when he realizes that they have some knowledge about where his friend might be. Along the way, he shows them the power of friendship and loyalty that he has learned in the Naruto universe, and they in turn show him the complex nature of the afterlife in the Death Parade world.
One of the most popular characters to write about is Nona. She has a mysterious air about her and her position of power in the afterlife gives her a lot of influence. Fanfiction can explore her motives and her plans for the future of the afterlife. Also, Ginti is often written about. His more volatile nature compared to Decim and his own unique style of running death games can be the focus of many stories.
Sure. The manga goes beyond what's shown in the anime and gives you a richer perspective of the universe it creates. You'll learn about hidden aspects and get a more elaborate exploration of its themes and settings.
