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

The conversation with the old Citskii was so long that by the end, everyone involved were sitting in various poses on the convenient rocks on the beach. Even the merfolk himself lugged himself onto a boulder, showing that below waist he had a fish tail instead of legs.

The conversation was also the most insightful.

First, they found that the kraken really was something like a pet to merfolks, though Citskii refused to say if there were more than one of these beasts. Then…

"What do you mean by that? What did humans do to merfolks?" Cael asked.

Citskii replied, with visible agitation and anger, that human mages had been—and still were—kidnapping merfolks in broad daylight. About that, he gladly told as much as he knew.
