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 let out a breath. This really was a fair battle, one which Cael couldn't finish in a single strike. He had to give Dante his due—the man worked hard. The petrification gas… however it was made, it was some genius alchemy. Not to mention hiding it in the walls.

By now, Cael understood how Dante did it. The walls underneath the whitewash were made from a solid compound that, when contacting with air, dissolved into gas. In the past, Cael saw something similar with swamp dragon poison, which was liquid when a dragon spat it out, but turned into gas when exposed to air.

It was another question how Dante replaced walls with the solid petrification gas, but the answer must've been Transmutation magic. A spell with an instantaneous duration didn't leave traces of Dante's mana in the walls, and the gas itself wasn't much more magical than normal rock.
