Clamping the hot body tightly, Caleb injected billions of essence. Coupled with the stimulation of the lightning element, Ruri Kurumizaka also experienced the sensations felt by Reina Hamasaki and Yukina Sasaki. Wave after wave, her small tongue protruded obliquely, her pupils rolled up. Ruri Kurumizaka trembled non-stop, falling back limp against Caleb in a daze.
Feeling the slight increase in magic power within him, Caleb picked up Yuuki Shinamura and continued his cultivation. The four girls in the Hamasaki group were roughly C-rank to D-rank. For Caleb, who had merged with the Devil Bloodline, the improvement wasn't huge, but it was much more effective than the Takamine sisters.
Caleb deliberately exposed the existence of the supernatural world because he wanted the Takamine sisters to also begin cultivating magic power. This idea was now even stronger. Not only for better Dual Cultivation, but also for their safety. Regardless of their talents, as long as they could cultivate, with Caleb's help, they would at least be able to defend themselves against ordinary attackers.
The Dual Cultivation ability replenished vitality and spirit. The Devil Bloodline and Primary Physical Mastery greatly enhanced Caleb's stamina. With the aid of the Enchantment skill, his ability to handle all four girls, which was already possible, became effortless.
Caleb didn't stop until the sky began to lighten. Four naked bodies lay sprawled across the living room floor. Their pale, beautiful legs were spread wide, and white fluid slowly flowed out of their swollen openings. Looking at the slightly bloated lower abdomens and the dazed eyes of the four girls, Caleb muttered, "I was too happy. I think I overdid it..."
While Caleb was cultivating all night, Rias and Sona Shitori were not idle either. After failing to convert Caleb into a peerage member, Rias made some arrangements, appointing Himejima Akeno to temporarily take over, and immediately rushed back to the Demon World. If she couldn't find the answer in the family's ancient texts, she would ask her older brother, one of the current Four Great Satans. If there was still no solution, she would look into other ways to sign a peerage contract... Playing with the Evil Piece carrying Caleb's aura, Rias's eyes flashed with determination.
Sona Shitori listened attentively to Tsubaki Shinra's report, one hand constantly flipping through books, the other quickly recording Caleb's information. With just one penetration of Tsubaki Shinra, they had figured out Caleb's Dual Cultivation ability, aside from its characteristic of copying talents and skills. This was the terrifying power of family heritage. Of course, this was also inextricably linked to the personal abilities and knowledge of Sona Shitori and Tsubaki Shinra.
"Similar abilities have existed before," Sona Shitori closed the thick parchment book. "But this kind, with absolutely no side effects, is certainly worth investing in."
"It's not entirely without side effects, is it?" Tsubaki Shinra gave a wry smile, her beautiful face showing a slight worry. "Although my strength has increased, there is this feeling of being exclusively marked..." The stronger one's power, the more sensitive one is to changes in their body. Caleb, having just acquired the Middle-Class Devil Bloodline, was able to perceive the truth about the Dual Cultivation ability. Tsubaki Shinra, of course, could also notice the changes in her own body.
"I think it's quite normal." Sona Shitori pushed up her glasses, calmly analyzing, "Being with Caleb not only satisfies the body, but also increases magic power. Even without that influence, you probably wouldn't be interested in other men."
The increase in strength is also inherently pleasurable, especially the growth of magic power. The stronger one is, the stronger the craving for magic power. Magic power and spirit are the foundation, more so than the body. As long as magic power and spirit remain, the body can be resurrected even if annihilated. Of course, there is still a price, and it requires considerable strength.
Tsubaki Shinra nodded. "Indeed, besides being tied to Caleb forever, there are no other downsides."
"Yes, and when Caleb's strength surpasses yours, you'll benefit even more." Sona Shitori pondered. "This kind of constitution, where both parties increase their strength simultaneously without any damage... seems unprecedented in history."
"Could the failure to convert him into a peerage member also be related to Caleb's constitution?" Tsubaki Shinra asked.
Sona Shitori shook her head. She wasn't sure either. Logically, the two shouldn't conflict, but the fact remained that Caleb's peerage conversion had failed.
Tsubaki Shinra furrowed her brows, whispering, "It might not be a complete failure."
"What do you mean?"
"When I took Caleb home, I thought I smelled an aura of a kindred spirit on him." Tsubaki Shinra's expression was uncertain. "The sensation was too faint. It's possible I was mistaken..."
"An aura of a kindred spirit? What specifically?" Sona Shitori looked curiously at Tsubaki Shinra. "Think carefully."
"It was the scent of a Devil. And it was of the same origin as mine, belonging to the Sitri family bloodline."
Sona Shitori took out the Evil Piece infused with Caleb's aura and let out a soft chuckle. "It seems it wasn't a total failure."
Caleb's Middle-Class Devil Bloodline came from Tsubaki Shinra, naturally sharing the same origin as hers. Through a happy coincidence, Sona Shitori and Tsubaki Shinra mistakenly believed this was a result of the failed peerage conversion.
"But in that case... will the Rating Game acknowledge Caleb's participation?"
Sona Shitori waved her hand dismissively. "There are many ways to convert a peerage member, and many are much more stable than the Evil Pieces." Since the birth of Devils, peerage conversions have been ongoing. The Evil Pieces were a method born of the modern era, which is why they are widespread. It doesn't mean it's the only way to convert a peerage member.
Strictly speaking, a peerage member is a servant, and the one holding the King Piece is the master. The only reason those converted by Evil Pieces are officially called 'peerage members' is that they lack a strict contract, and it sounds better.
"Yes, that's right. Even if you were mistaken, we can try again using other methods." Sona Shitori thought for a moment, then added, "However, we'll need to report it then, and probably submit one of the Evil Pieces." Sona Shitori's older sister is also one of the current Four Great Satans, which gives her this leverage. For anyone else, it wouldn't be so simple. If everyone did this, the Evil Pieces would have no reason to exist.
Despite their different lines of thought, Rias and Sona Shitori, the two friends, had simultaneously arrived at the same solution.
...
...
After sending a sick leave text from the four girls' phones, Caleb began cleaning up the messy living room. Before that, he needed to clean the four unconscious, naked bodies.
When the Takamine sisters woke up, Caleb had just finished cleaning the four girls.
"Ayame-nee, Yuri-nee, take the day off today and help me look after them," Caleb said as he carried the weak Yukina Sasaki toward the bedroom. "Yukina, I want you to help guide them when you have a chance. I want Ayame-nee and Yuri-nee to learn magic too."
Yukina Sasaki lazily glanced at the Takamine sisters and licked Caleb's neck. "Guidance is fine, but we can't guarantee they'll learn anything~~"
"Stop teasing, if you start a fire, you'll be responsible for putting it out."
Instinctively touching her slightly bloated lower abdomen, Yukina Sasaki's body stiffened, then she obediently snuggled into Caleb's embrace. She couldn't afford to be naughty. Not only was her stomach full, but her valley was throbbing. Putting out a fire now would only torture herself.
After settling Yukina Sasaki in the room, he brought in Reina Hamasaki, Ruri Kurumizaka, and Yuuki Shinamura, respectively. Similarly, Caleb instructed them to guide the Takamine sisters on how to begin their magic training once they had recovered a little. The three girls nodded in agreement and then quickly fell into a deep sleep.
"M-Master, who are they?" Looking at the four beautiful girls lying under the covers, Sayuri Takamine was slightly unhappy. "Did you sneak out and do it all night after we fell asleep last night?"
"They are my classmates, and they also know magic," Caleb squeezed Sayuri Takamine's delicate face, smiling. "They were with me even before you two were~"
"Including Tsubaki-senpai yesterday, that's already five." Sayuri Takamine pouted angrily. "How many other women do you have out there?"
Caleb thought for a moment and said earnestly, "Just these for now, but there will probably be more in the future."
"Wuu!" Sayuri Takamine puffed out her cheeks, her small face written with displeasure. She knew she couldn't have Caleb all to herself, but it still made her feel uneasy.
"Don't worry. No matter how many women I have, your Master will never neglect you two." Caleb meant to say something comforting, but the words came out sounding like a command. Because of his effective discipline, the Takamine sisters didn't feel anything was wrong. Ayame Takamine, especially, didn't care at all how many women Caleb had. As long as he satisfied her, she didn't care about his promiscuity outside.
