My Unique Skill is Fate Gacha(DxD)

Ryougi Kazuya didn't know that this would be his last roll.

One moment, he was just another player trying his luck in Fate/Grand Order. The next, he was surrounded by flames, his cell phone exploding in his hands - and when he woke up, there was no hospital, no ambulance. There was only silence... and a strange sky over a city called Kuoh.

Reincarnated into the world of High School DxD, Kazuya finds himself trapped in a reality where demons walk disguised among humans, where fallen angels hunt in the shadows, and where the strong make the rules - or die trying to break them.

But Kazuya didn't arrive empty-handed. A unique power awakens within his body: Fate Gacha - the ability to summon, once a day, any resource from the Fate universe. From divine armaments to legendary heroes, everything is within his reach... if he's lucky.

Now, with the body of an irresistible young man but the misfortune of a doomed Lancer, he must fight to survive on a board where every move could be his last. Amidst supernatural intrigue, hidden wars, and girls who hide blades behind smiles, Kazuya begins to understand an uncomfortable truth:

In this world, destiny is not something you follow. It is something you defy.
