Harem Overlord

"The smell of these books feels nostalgic," Esmeralda muttered as she looked at the library again.

She hadn't visited this place for some time and her last trip had been well over a month ago and that too because she had needed books to teach Lana.

The wolf girl, as it turned out, did not know a lot of basic things. And since Esmeralda was an expert in these things, she decided to take it upon herself to teach Lana.

After that, she hadn't returned to the library for any kind of thing since she had been too engrossed in teaching.

If not for Kai, she probably wouldn't have come there for another month or two.

"What do you want from here?" Esmeralda asked as Kai told her about what he and Sahara had experienced.

The half-lion girl stood in the corner with a bored expression as she looked around and searched for a book to read. There wasn't anything major in the entire place but she did find a book on spiritual lions.

While she read that, Kai finished the story for Esmeralda as the pink-eyed librarian looked around the library with an interested look.

"I once read about something related to that. I think such a book was in the bloodline section."

"Why would it be in the bloodline section if it is something related to the mind?" The purple-haired man had no idea about what Esmeralda was saying so he left the librarian to do her job.

While she did that, he went near Sahara.

"What are you reading about?"

"Did you know that in some places, a spiritual lion's roar is considered as a good omen while in some places, it is considered as bad luck?" The half-lion girl asked as she lifted her face from the book she was reading at looked at Kai.

The purple-eyed man was taken back when he heard these words.

"What am I supposed to do with this information?"

"You are supposed to study such things and gather more knowledge on the topic of lions," Sahara replied and continued reading.

Before that day, Kai had never known that Sahara could get herself buried in reading such books. He then sighed and started waiting for Esmeralda to come back.

'What if she started reading smut books.' As soon as that thought entered his mind, he couldn't stop himself from thinking about it.

But after a few minutes, the librarian returned back with a black-colored thick book in her arms. She waved the book in Kai's direction as he released a sigh of relief knowing that she hadn't gotten distracted by smut books.

"This should tell you all the things you need to know though you will have to do some searching around. So can you please teleport me back so that I can continue my session with Lana?" Esmeralda asked while raising an eyebrow.

"As you say," Kai said and snapped his fingers and the librarian went back to her room.

"Sahara, you can continue reading about lions later on. Let's first see what happened with Lily and Mila." Kai said to the half-lion girl who raised her hand raised her head from the book again.

"You need to first find about the stuff before we read and find what happened. I can't help you there." Sahara replied and kept reading.

Kai sighed and started scrolling through the book. It told a lot of things about bloodlines however it didn't have an index.

This meant that Kai would have to keep reading until and unless he found what he was looking for and judging from how thick the book was, it was going to take him some while.

'Whoever created this book definitely had a lot of free time on his hand.' He thought with a sigh and after a few hours of searching around, he finally found what he was looking for.

"Some ancient demon texts say that the sins have the ability to pass a specific power they have through their blood. The ability can be chosen by the sin and would continue to go on for generations unless the sin decides to take it back." Kai read out loud as Sahara suddenly closed the book she was reading and put it back in its place.

"I never knew that we had this ability. Where did this guy even find this ancient text he is speaking of?" Sahara asked with a baffled look as Kai shrugged.

He read a little more but there was no mention of the texts in the book. After he was done with his reading, he decided to go ahead and see whether this was true.

"Sahara, let's test whether this theory is true or not," Kai said as he closed the book and put it inside his pendant.

The sin of pride then thought about it for a few seconds before she decided what ability she wanted to use.

"Open your mouth I guess." She said as Kai opened his mouth a little. She then raised her right hand over his mouth and bit her index finger.

After dripping a drop of black blood in his mouth, Sahara waited for something to happen.

And a few seconds later, two cat ears appeared on top of Kai's head.

"Out of all the things you could have done, you decided to give me these?" Kai asked with a baffled look as Sahara burst out laughing.

"They are useful thou. You can hear better with them than your original ears." The half-lion girl then closed her eyes and thought that the ears on Kai's head were gone.

And a few seconds later, they vanished.

This meant that what the book had said was true and Lily and Mila had somehow gotten to know about this thing and had used it to give their abilities forward.

However, the question was why?

"Kai, maybe we should go ahead and take Lily. We need to question her about this."

"I guess we are back to kidnapping people then."
