Underworld.
lucifugus Family Castle, in a training ground.
"Hmph!"
Linde, having finished several hours of cultivation, felt his magic power completely depleted.
He gently exhaled a breath of turbid air, sat on the ground, and wiped his sweat with a towel, yet he looked at the sky, clear as a lake, with a hint of melancholy.
He was a transmigrator; this was his second life.
Only a few days ago had he broken through the mystery of the womb.
In this life, he was not human, but a hybrid of human and demon.
However, as an infant, he was adopted by the lucifugus Family on the battlefield, becoming Grayfia's foster brother.
"Not bad at all."
Linde sighed.
With Grayfia as his backing and the cultivation resources of the lucifugus Family.
His strength had recently risen to the level of an Upper-level Demon.
For his age, that was considered very strong.
However… "This world is truly a bit outrageous."
Recalling the information he had gathered, Linde's eyelids twitched.
This was a world where multiple anime from his previous life had merged.
Just by looking at the map of the human world, he could see familiar names.
Komaou Town, Fuyuki City, Chiba City… Beneath the calm daily life, countless anomalies were hidden.
Demons, Angels, Fallen Angels, Sorcerers, Exorcists, Yokai—these were no secrets to him as a demon.
He even saw records of Anti-Magic Ninjas and Heretic Gods.
This almost made Linde lose his composure.
This world truly had a good appetite; it dared to merge everything.
"You're here, as expected."
A gentle voice sounded in Linde's ear.
Linde turned his head.
A tall woman with long silver hair and a cool temperament had already entered his sight.
She wore a pure white long dress, and her entire being exuded an indescribable nobility and wildness.
She was like a noble young lady, yet also like a warrior who had galloped across battlefields.
The person who arrived was none other than Grayfia lucifugus.
Because of Linde.
Her trajectory had already shifted.
There was naturally no need for her to wear a maid outfit.
"Sister Fia, you're here."
Linde smiled, trying to get up but stumbled.
The next moment.
A soft sensation enveloped him, and Linde felt himself sinking into a warm embrace.
Grayfia helped Linde up, completely disregarding how her intimate actions gave Linde a bit of a 'bonus'.
"You, don't train so desperately. With me here, no one would dare to cause trouble for the lucifugus Family."
Looking at Linde, Grayfia complained softly.
"I just want to become stronger."
Linde shook his head.
This world truly made him feel insecure.
Grayfia was strong, true.
But in front of the world's top powerhouses, she was still not enough.
Moreover, how could a man hide behind a woman?
"My little Linde will definitely become very, very strong."
A smile appeared on Grayfia's face.
She genuinely believed so from the bottom of her heart.
Linde's cultivation speed was stronger, not weaker, even compared to most pure-blooded demons.
And… how could the man she favored be anything less?
"Sister Fia, can you drop the 'little' part?"
Linde was a bit speechless: "I'm an adult now."
"Is that so? I don't see it?"
"Then do you want me to prove it to you?"
As he spoke, Linde had already playfully wrapped his arm around Grayfia's slender waist.
"Oh, it seems you want to rebel?"
Grayfia's cheeks flushed, but she didn't avoid Linde's gaze.
If not for a girl's modesty, she would have confessed long ago.
"How could I?"
Linde smiled: "It's just that my magic power is severely depleted, and I just want Sister Fia to replenish it."
Grayfia paused.
Linde seemed truly different.
He had become so bold.
Before, when she actively suggested replenishing his magic, he always refused.
But today… had he finally caught on?
Thinking this.
She saw Linde's face drawing closer and closer.
Hmm… Grayfia's pupils contracted sharply.
Her mind… felt so hot.
Linde's eyes flickered, feeling his magic power recover.
What was called 'replenishing magic'.
It was a method of replenishing magic power through the exchange of bodily fluids.
This was a method used only by close individuals within the demon community.
"Little Linde, confess honestly, have you been secretly messing around behind my back?"
Grayfia's eyelashes trembled slightly, her lips pursed, looking at Linde somewhat indignantly.
He was too skilled.
"I just have a lot of theoretical knowledge?"
Linde replied righteously.
This was truly his first time replenishing magic.
As for other things.
What happened in his previous life, of course, had nothing to do with this life.
"Is that so?"
Grayfia blinked, then smiled provocatively.
"Then I'll have to properly confirm it."
"Do as you please."
Linde and Grayfia's eyes met, as if there was nothing else in their eyes but each other.
"Cough, cough."
Just as Linde was about to lose control.
A cough came from the doorway.
Instantly, Grayfia jumped to the side like a startled rabbit.
Her ears were flushed, and she felt a little frantic inside.
It's over.
It was all Linde's fault.
She hadn't even noticed someone had arrived.
Could they have seen everything?
"Oh my, it seems I've come at a bad time."
Rias leaned against the wall, her eyes a bit jealous.
Because of the cooperation between the Gremory Family and the lucifugus Family.
She and Linde were childhood sweethearts, in a way.
Now, seeing all this, she felt an inexplicable irritation.
"Rias, why didn't you say you were coming beforehand?"
Grayfia took a deep breath, steadying her emotions.
"Wasn't it something you instructed?"
Rias rolled her eyes, "Linde's enrollment at Kuoh Academy has been settled."
"He can report there sometime soon."
Upon hearing this, Linde's face showed understanding.
Because of the tight devil population, many devil families, after their offspring reached a certain level of strength, would send them to the Human World to recruit Retainers/Subordinates and cultivate their own forces.
"I almost forgot about that."
Grayfia realized, then turned and said, "Little Linde, we talked about this."
"You haven't changed your mind, have you?"
"Of course not."
Linde nodded.
It would be a lie to say he wasn't curious about this hodgepodge world.
He wanted to know how crazy it truly was.
"Alright, here's your transfer application."
Rias took out a piece of paper and handed it to Linde, saying,
"You can come visit my club when you get there."
"That way, we can look out for each other."
After giving some instructions, Rias left, leaving a number before she went, saying he could ask her if he didn't understand anything.
After noting down the number, Linde turned and said, "Sister Fia, now that Rias has left, can we continue?"
Grayfia's expression stiffened.
Was he this aggressive already?
She felt like she couldn't quite handle it.
Even though she had long since accepted Linde in her heart, things were progressing too quickly.
"Oh, right, I think I have something else to take care of."
With that, Grayfia hurriedly walked out.
