Rustle~ rustle~ chu~ smooch~
"Mnhm~"
"Haah.. your lips are so delicious Rias.. haah.. I already feel my magic replenishing at an astounding rate."
What is magic replenishment?
This is one of the most common methods for restoring magic in the mystical world.
Although there are many ways to replenish magic, exchanging bodily fluids is the most efficient.
"Haah~ O-Ok! Alright, enough.. huff.. haah.. are you hiding something from me? Have you been reading some inappropriate materials?"
Rias leaned languidly on the table, huffing, her cheeks already flushed, yet she still looked directly at Kuroki Ren, her beautiful eyes sparkling with a strange light.
"What are you talking about? You were the one who suggested it, you know." Kuroki Ren's face was filled with righteousness.
He'd be looking down on himself if he let such an opportunity slip away.
That said, he had to admit—magic replenishment was truly effective; his magic power had mostly recovered.
"Oh my, did I interrupt something?"
At the entrance of the library, a tall, beautiful young woman with waist-length hair tied in a ponytail appeared at some unknown point. She exuded the elegance of a true school goddess.
In terms of beauty alone, she was on par with Rias.
"Akeno, how did you get in?"
Rias's body stiffened slightly.
It had been her first kiss, and even if the one witnessing it was Himejima Akeno, she couldn't help but feel a little embarrassed.
"Isn't it because I waited outside for too long?"
Himejima Akeno's gaze swept over the two of them, her eyes narrowing slightly, a mysterious smile playing on her lips.
"If she likes to watch, let her watch. I still need a little more magic power to fully recover."
As he spoke, Kuroki Ren moved closer to Rias again.
"Rias Buchou, have you given Kuroki Ren the item?"
Seeing this scene, Himejima Akeno found it hard to maintain her composure.
What was going on?
When did Kuroki-San become so shameless?
Although she didn't mind waiting...
Being fed "dog food" so openly was still annoying.
"Ahem, there is indeed serious business to attend to."
Clearing her throat, Rias had already regained her graceful demeanor.
Then, with a wave of her hand, a pale purple magic circle flashed and disappeared.
In her hand, a set of international chess pieces had appeared.
"Devil Chess Pieces?"
Kuroki Ren's eyes flashed.
These were developed by Beelzebub, one of the current Four Great Devil Kings, to enhance the power of devils and increase their numbers.
It was a technique that could transform other living beings into devils.
"Here— from now on, this set of Devil Chess Pieces is yours."
"Thanks."
Kuroki Ren didn't stand on ceremony and took them directly.
Rias smiled and cautioned, "Each set of chess pieces has a limited number, so be very careful when choosing your Peerage."
"It's best if they're special races or Sacred Gear possessors."
After explaining a few things, Rias left the library with Himejima Akeno.
Peerage?
Picking up a Devil Chess Piece, Kuroki Ren didn't pay much attention to it.
If it had been before this—
He would've definitely done everything he could to use the Devil Chess Pieces to reincarnate powerful servants.
But now, the most urgent task was the newly arrived system!
Then, with a thought, his virtual panel appeared.
[Notice: Origin +10]
Seeing the notification on the panel, Kuroki Ren was slightly startled, but he quickly turned his attention to the subtle, mysterious patterns on the Devil Chess Piece.
"So that's it... is this how Origin Points are obtained?"
What was Origin? It could be considered one of the foundations of the world.
So everything—even knowledge—should be a component of Origin.
"No wonder I had so many Origin Points at the beginning. It must have come from everything I've seen and experienced over the years."
Thinking this, Kuroki Ren casually picked up a book from the shelf and began flipping through it.
He skimmed it, reading at lightning speed—ten lines at a glance. Only after finishing the entire book did he see another notification.
[Notice: Origin +1]
Looking at the new information, Kuroki Ren mused:
"It seems the acquisition of Origin Points isn't fixed. From the current results, items related to the supernatural yield more points."
Thinking that, Kuroki Ren placed the book back and sat down in his chair again.
He flipped his palm, and the light of a magic circle appeared in the air.
With a rustling sound, books fell onto the table.
All these books came from the Underworld, and their content could be considered quite varied—but all were extremely valuable.
Because these were all forced upon him by Rias to help Kuroki Ren improve his strength.
However, for a long time, in order to become stronger as quickly as possible, Kuroki Ren, without his previous life's memories, had focused solely on studying Thunder Magic—aside from a few practical spells.
He hadn't even looked at the other magic books.
Casually picking up a book, Kuroki Ren began flipping through it rapidly.
[Notice: Origin +3]
[Notice: Origin +5]
Before he even finished a single book, hint texts began appearing continuously.
"Indeed, my guess was correct."
Kuroki Ren's eyes grew brighter and brighter, and his page-turning speed increased without him realizing it.
Fortunately, he was now a devil, and his memory far surpassed that of an ordinary human.
Not long after, one book had been finished.
Then—
Kuroki Ren didn't rush to add points, but picked up another book to continue reading.
As more books were completed and more Origin Points accumulated, Kuroki Ren also discovered something else:
No matter what it was, as long as he saw it, he didn't need to understand it to gain experience.
Unconsciously—
It had already become late at night.
Kuroki Ren had stayed in the library the entire time, yet he felt no fatigue, as if he had completely lost track of time.
"Let's stop here for now..."
Setting down a book, Kuroki Ren summoned his virtual panel.
[Kuroki Ren]
[Profession: Original Magician]
[Magic: Thunder Magic LV41 (+)]
[Origin: 1815 points]
Rubbing his somewhat sore eyes, Kuroki Ren began to allocate points with a thought.
Buzz! Buzz! Buzz!
Light flashed continuously on the virtual panel.
Kuroki Ren felt the magic power within his body begin to surge like a raging tide.
His surroundings seemed to transform into a domain of thunder—everywhere he looked, there was only lightning.
Finally—
The light gradually faded.
[Kuroki Ren]
[Profession: Original Magician]
[Magic: Thunder Magic LV60 (+)]
[Origin: 1182 points]
...
Kuroki Ren stared intently and noticed a new notification on the panel:
[Ding, Thunder Magic has been upgraded to Level 60. Do you want to spend 1000 Origin Points to complete the class change?]
