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~

Cael brought his hands together and stretched them wide, forming a blade of wind between them.

It was enough of a provocation for the centipede. It wiggled its mandibles and charged at Cael with an impressive speed for a beast of that size.

He was still faster, though. With a beat of his wings, he jumped away, sending the massive wind blade right at the creature's neck.

This blade had little in common with low level Wind Blades beyond the fundamental structure. Cael used known meta-forms and repeated them until the blade became so charged with mana that it could count as a level six spell.

It wasn't big, but flew with such speed that it was almost instantaneous. The speed was so fast that instead of swishing of air, there were only two bangs—first when it began to move, and second when it hit the target.
