Slime x Male Moon Breath User (this is not a pairing of Rimuru and the reader)

Devils, angels, fallen angels. We've heard them all, most would say devils are evil and angels are nothing but holy. One individual can agree with the cliché of devils being unforgivable due to a past experience with the underworld residents. (Y/N) (L/N), a boy with mystery surrounding both himself and his past, he holds a powerful weapon unheard of and impossible to wield for any of the three factions. This causes him to become both a valuable ally, and a dangerous foe for the three races, but (Y/N) doesn't care as he only has one goal in mind: to annihilate every devil he comes across... I do not own Highschool DxD or any of its characters, the only thing I own is this story.

A small slime finds a new master in a forest. But this slime wasn't always the way he is now.

Inspired by @Astro_Reaper22 and @TheWidowMaker, I decided to make a dxd x male reader(this is my first book so don't hate on me okay?) Disclaimer: I don't own High School DXD. Y/n Gremory-Bael, third child of the Gremory household, was always loved by his family, especially Rias his older sister, Venelana his mother, and Grayfia his personal and trusted maid. He always draw attention to every female in the Underworld, including angels and fallen. He's always nice to all kinds of devils, angels, fallen, including Azazel, and Michael. One day, he woke up with a purple gauntlet that is more powerful than Ophis, Great Red, Albion and Ddraig combined. Few years later, he decided to visit Kuoh Town to see his sister(a.k.a a huge brother complex to her younger brother) and attend the school where his sister studies. Few days later after attending Kuoh Academy, he learned that a brown haired boy who has a Welsh Dragon Emperor sacred gear was stabbed by a light spear which was thrown by a fallen angel and was reincarnated as a devil by his sister.

Y/N Tsugikuni. A demon slayer who was living a average life hunting demons until he met Upper Moon one in an unexpected encounter had his life changed forever. Start - 10 May, 2021 End - 9 November, 2021
