Garessta

In this world riddled with strife, where even kids know spells, and powerful mages are nobility, Cael was born with no mana at all. An heir to the family of mages, he was his father’s disappointment, and his city’s laughingstock. But who knew that he had a much different destiny? To prevent a looming catastrophe no one else knows about—to stop the Starspawn. 

“Blood Mage System activated. Greetings, user. I am your Blood Mage System. Consume the blood of powerful creatures to purchase new abilities.”

With that power, Cael will become a hero able to stand against the fate that crushed countless others—even if the world will call him a demon instead.

Although the novel has a harem and r18, neither are the focus of the story. Cael only has very few (2 right now and at the moment I don't plan on increasing this amount) girls, and there aren't that many r18 scenes. Take that as you may~

My Blood Mage System

Cael didn't count how many dragons he had to kill or maim on his way to the capital, but it was more than five and less than fifteen.

An individual dragon wasn't too much of an opponent for him, except for a rare quicksilver dragon, but the lot of them exhausted Cael's stamina and patience. The former could be refilled with dragon blood—the latter couldn't be.

When he finally reached the outskirts of the capital city, he breathed out in relief, because there were much fewer dragons there. But there was the same amount of chaos.

Instead of dragons, the city was attacked by ejderha—that was a fresh development. At any other time, Cael would've intervened, but right now he made a beeline straight to the embassy of the Kingdom of the Bear.

His heart sunk when he saw from the outside the damage done to the building. The doors were blown open, and traces of extinguished flames showed that a battle had happened there not so long ago.
