AN1: Goku black/ Zamasu in DxD

AN2: Idea for small word range fic (around 30-40k words)

AN3: Blood/gore/massacre fic idea

Why I am writing this idea: I read a fic of DBS x Naruto where Zamasu is transported to Naruto world and massacre them, but they are saved by Goku and company. The execution of that story was wonderful. And the blood/gore written in that fic was amazing.

Title Idea: The rose of terror

During the final clash between Trunks (who got dragon balls history thickest plot armor) and fused Zamasu.

(Some changes will be there)

Goku summons Zeno before Zamasu could combine itself with the universe killing every living being. Zeno is angry at the being in front of him, who has transcended the divine realm and evolving towards becoming universe itself. Zeno erases Zamasu and just as he is about erase the whole dimension, Goku stops and pleads him that he spares the mortals who doesn't have anything to do with that abomination. Zeno thinks for a few seconds before saying that he will erase this universe and reconstruct it. Zeno's hands start to glow and sensing the danger of staying any longer, Goku and company fled to their own dimension.

(Just before Zeno erased Zamasu)

Zamasu is shocked by the turn of events, as he didn't expected Zeno would show up. Zamasu tears a small part of his soul which contained universal energy (God ki/God chi/whatever you can call it) and releases it outside the planet. As he predicted, he was no match of Zeno and was erased, but no one sensed the small part of his soul has escaped.

Zamasu soul is traveling across the universe in search for a new body. But he never expected that his soul will be captured by one of the minions of King Yemma and is send to him for judgement. As there are many souls to be judged, king Yemma has many low levels king Yemma (one we see in dbz) who judge souls at mortal level. Since, Zamasu soul piece is half mortal and half divine, it is sent to low level King Yemma.

At low level king Yemma place

King Yemma is in hurry as the swarm of souls are swarming his place due to recent massacre of Zamasu. So, due to hurry he just horribly judges the souls without looking and sends everyone to the cycle of reincarnation. Zamasu is happy that King Yemma didn't saw him or else it would've ended much more horribly for him.

Zamasu's soul enters the cycle of reincarnation in DxD universe.

Zamasu is born as human (white hair is the only thing he got to keep, which he quickly changed to his original mohawk style) and loath himself for the mortal body he got and ponders on his life decisions. He has still got his Divine ki/ God ki, but it is too small to used for anything other than just creating small fireworks which is loved by his little sister.

7-8 years have passed since Zamasu has been born in his new body.

Zamasu mentality has changed much since his reincarnation, he is now able to understand the struggles of mortals and is re evaluating his decisions of zero mortal plan. He still hates every human as they are greedy, filthy, etc. But the only thing he now loves more than anything is his little sister who he will protect, even if he has to give up his own life for that.

Zamasu is now 17 year old.

With great "luck" he is able to enroll in his little sister's (who is 16) school (Kuoh Academy). His main goal was to protect her from the perverted male humans who have enrolled in now co-ed Kuoh all girl school.

He allowed her sister to enroll in this school because it was all girl school and she will not be tainted by males before reaching the age. But he became angry when the school decided to go co-ed and tried everything in his power to stop the school going co-ed, even going as far to legally file a case against them. But he forgot, he is nobody on Earth and Money/Power is everything on how humans operate.

Zamasu was very angry after that (I mean very angry). He swallowed his pride and also enrolled in Kuoh.

Before Zamasu joined Kuoh

Zamasu's little sister becomes a devil (sona's peerage) when she joins the student council of Kuoh academy. She wasn't willing to become a devil first, but was tricked by Sona into becoming one as Sona listed all the benefits of being a devil. She just wants to protect her brother who has protected her since her birth (flashback of Zamasu saving his sister can be added here). She wanted to become independent and also wants to protect her brother so she accepts becoming a devil.

Zamasu is oblivious of the fact that his little sister has become a devil. He is suspicious about the energy in his sister's body but dismisses it thinking that some of his divine ki must have leaked inside her mother's womb when giving birth to him, which was later absorbed by his little sister.

End of fic idea…

Suggestion:

1. Zamasu power will increase the more he battles (like how saiyans evolve the more they fight), Zamasu will not know about this until his first battle and recovery. Zamasu and his little sister (your choice who you chose from sona's peerage to be his sister) will have a healthy sister and brother relationship. Please no sis-con or brother-con, no incest please.

2. Zamasu will not join any side, as he hates everyone other than his family.

AN: Please let me know if you decide to take any part from this idea, I will love to read how your fic.

Thanks.
