His father died to save him; now, the Underworld will burn to avenge him. Reinhardt Phenex has woken up with a "System" that holds the keys to godhood and a thirst for absolute sovereignty.

Fairy Tail and Highschool DxD crossover. Natsu Dragneel a 19 year old high school student trying to live his everyday life as a regular human along with his little sister. Except he is everything but human. Natsu is a dragon slayer with the ability to slay dragons and have them at his mercy. But he also hides another terrifying power that he tries to keep hidden from his friends and the woman he loves. Only a few know about his true identity only a few know what he actually did. Will he be able to keep his dark part a secret? Or will all his past demons come back to haunt him?

My name's Matthew Lucifer I am the son of Rizevim Lucifer and a human woman. I am also this generations White Dragon Emperor. This is my story.

As we know issei and rias are always destined together but what if there is another red haired gremory which is also his childhood friends so witness the journey of issei and Riley on this story

y/n was a normal person who lived in very snowy areas with his family, that is, before an avalanche got to them and took everything he held dear from him. Yet, fate decided to have mercy on him, as he ended up being found by Odin, the All-Father, who took him in as his own, as y/n is completely unaware of the power dormant within him.

In a world of devils, angels, and gods-where power is inherited, bought, or blessed-she simply was. Born under a trembling sky, Sigrid came into the world like a fracture in fate itself. A strange girl with pale hair, sharp eyes, and no place to belong. Raised in silence, watched by ancient elemental spirits no one else could see, Sigrid lives hidden on the edge of the supernatural world... until the day devils come for her. What follows is not her fall. It's her awakening. Now under the wing of Azazel, the enigmatic leader of the Fallen Angels, Sigrid steps into a world that doesn't know what to make of her. She's not a Sacred Gear wielder. She's not a reincarnated soul. She's not even supposed to exist. But she's here. And the world is watching. I do NOT own HighSchool DxD. The only thing I own is my OC.

One day, a young devil by the name of Nova Gremory was grappling with two dire problems. On one hand, there was the upcoming arranged marriage of his big sister Rias to that flaming asshole Riser Phenex, something he absolutely refused to allow. On the other hand, there was the disappointing lack of the Peerage that he so longed for. However, a summons from his big brother Sirzechs gave him the solution, the biggest challenge of his young life... romancing a Leviathan!

Oh, I have a bad feeling about this. (Chaos Gacha, SI, Harem) [Originally posted in Snippets story]
