Chapter 220: Succubus Contract
"This contract is quite special—only the succubi of our lineage can use it."
Though she said "this lineage of succubi," in reality, only she, her mother Sheila, and her half-sister Lucia remained.
Only the three of them knew this contract ritual, and only they could use it.
Maria continued explaining, "Moreover, the conditions for establishing the contract are quite strict. It must be performed on a full moon night, and both parties must enter the contract voluntarily."
Rias crossed her arms, not rushing to respond, but instead asked, "Could you explain the contract's contents and effects in more detail?"
Due to the changed worldline, Sheila hadn't been captured by Zolgear yet, so the succubus loli naturally wasn't under threat and didn't need to tamper with the contract.
Not that tampering would be effective anyway.
Leaving aside Haruto's spiritual contract talent, Rias and the others were certainly not magic novices like Toujou Basara and Mio.
When establishing such an important contract, they wouldn't just accept whatever this unreliable H-succubus loli said at face value.
If anything seemed off, Rias wouldn't hesitate to interrupt the ritual.
"This contract is a type of master-servant contract with only one restriction: the servant cannot betray the master and must be unconditionally loyal, not even entertaining thoughts of resistance or doubt..."
Maria grinned, a lewd expression appearing on her face.
If this expression were on a man, it would surely seem perverted, but on a petite, cute white-haired loli, while strange, it wasn't quite as repulsive.
Mio swung a chop with a look of disgust, stopping Maria's delusions. "Keep going, don't go crazy."
After nearly a week together, she had already figured out the succubus loli's personality.
With her cute appearance, she spoke in a rather lewd manner and even enjoyed recording erotic videos.
"Mio-sama, that's too harsh... Can't I even imagine now~"
Mio narrowed her beautiful eyes and clenched her pink fists. If it weren't for the fact that the villa was full of girls, the erotic incidents she'd encountered these past few days would have already "ruined her reputation."
"Maria—"
A sinister voice sounded from behind, and the succubus loli immediately covered her head with both hands, not daring to cause any more trouble.
"Ahem, it's because of the succubus contract. Once the terms of the contract are violated, the servant will be subjected to an aphrodisiac effect."
Maria quickly got back to the main topic.
"Note that this aphrodisiac effect isn't just about making the servant aroused; it also continuously gives them pleasure. As long as they don't sincerely submit to their master, this pleasure will keep going."
"This pleasure is very intense, possibly even stronger than actual intercourse. Since it's a contract effect, it affects everything from the soul to the body."
At this point, the succubus loli paused and added, "Well, all of this is what my mother told me. This contract hasn't been used by anyone for a long time. At the very least, neither my sister Lucia nor I have ever used it."
After hearing this, everyone quietly pondered. A contract condition as abstract as loyalty was indeed troublesome, as no one knew exactly how the standard was judged.
What if it required something like a well-intentioned lie? What would happen then?
Not dwelling on such vague matters for too long, Haruto spoke up and asked, "Can this contract be dissolved?"
Because of his spirit contract talent, he asked this question purely for Rias's sake.
If it could be dissolved, then it wouldn't matter. After the Rating Game ended, they could just dissolve the contract. But if it couldn't...
Maria shook her head, and the answer, as expected, was no.
Haruto really wanted to participate in the Rating Game and eliminate all unstable factors, but he couldn't make a decision for Rias based solely on his own desires.
This was a matter that would affect her for a lifetime.
Haruto turned his gaze to Rias, who gave him a slight smile before he continued speaking.
"Maria, since the contract terms are so strict, the effects must be quite powerful, right?"
"Of course! After the contract is signed, depending on the bond between master and servant, both sides will experience a significant increase in power."
The succubus loli said proudly, "There's a simple way to enhance power—just engage in lewd behavior~"
This contract was a perfect match for Haruto's dual cultivation ability.
After hearing Maria's explanation, Rias and the other girls all thought the same thing.
At that moment, Haruto also recalled more details about the contract.
The effects of the succubus loli's contract mainly depended on the bond between the two parties. If it was purely a physical relationship, it was unlikely to maximize the contract's effects.
But when it came to lewd behavior...
Becoming one and finishing inside was already the ultimate act. Even if it couldn't fully bring out all the effects of the contract, it definitely wouldn't be far off.
Moreover, he was confident that his bond with Rias and the others wasn't weak. Perhaps once the contract was successfully formed, it could achieve 80-90% of its effects.
Haruto instinctively glanced at the snow-white necks of the girls.
According to memory, the contract would form a heart-shaped collar on the woman's neck, similar to the family crests Rias and Sona had engraved on his palm.
It would manifest when magical power was activated, and as the contract's effects strengthened—meaning as the master-servant bond deepened—the collar would continuously change colors.
If he remembered correctly, the sequence was red, orange, yellow, green, cyan, blue, purple...
Haruto couldn't quite recall whether it progressed from front to back or back to front.
Similarly, it seemed there was a restriction placed on the servant after the contract was signed.
Violating it apparently had severe consequences, but his memory was hazy on that as well.
While Haruto was struggling to recall, Rias had already made a decision.
"Tonight happens to be a full moon, and tomorrow is the final deadline to submit the battle roster."
The red-haired beauty pressed her hands against the solid wood desk, her exquisite body leaning slightly forward. Her full, rounded breasts hung heavily against her chest, their graceful curves utterly mesmerizing.
"There's no time to waste. We'll begin preparing the ritual now and formally sign the contract as soon as it gets dark."
Maria blinked, momentarily taken aback by Rias's decisiveness.
She instinctively glanced at Haruto. Judging from earlier fragments of conversation, Haruto should be the servant.
For this special contract that hardly affected the master, the key was whether the servant agreed or not.
Haruto nodded, then after a moment's thought realized the succubus loli had misunderstood, so he specifically explained the reasons behind it.
"There's actually such an ability?" Maria marveled, clicking her tongue in amazement before falling silent.
During these past few days of getting along with all the girls, she and Mio had basically learned about everyone's circumstances.
Compared to dual cultivation talent, the Sacred Gear Red Dragon Emperor's Gauntlet, and Haruto's astonishing rate of improvement, the spirit contract talent seemed rather underwhelming.
Also, having learned about Haruto's promiscuous lifestyle, the tsundere twin-tailed girl who had initially been quite fond of him hadn't spoken much to him these days.
Haruto could do nothing about this but let things take their natural course.
It would be unrealistic to say he didn't want anything to happen with Mio, but after experiencing so many girls—especially after being with the members of the Occult Research Club—he would no longer force anything.
Just like how he deeply wanted to sign the succubus loli's master-servant contract with each of the girls to strengthen their bonds and deepen their relationships, whether to sign the contract was entirely up to the girls themselves.
Forced melons aren't sweet, but they quench thirst.
Haruto agreed with this saying, but right now he wasn't thirsty at all—instead, he was drowning in floods...
Just in the few days since returning from special training, the nightly orgies at the Takamine residence would promptly begin.
If not for the health and mana recovery effects of the dual cultivation ability, even SS-rank strength wouldn't withstand such daily draining.
Early June, with less than half a month until the summer solstice, meant nights arrived quite late.
After preparing the ritual and everyone handling their miscellaneous tasks, the sky only then began to darken.
After waiting about another hour, the bright full moon finally appeared in the clear night sky.
Soft moonlight streamed through the window onto the clubroom's wooden floor. The magic circle drawn with magical materials gradually emitted a bright yellow glow under the moonlight.
The warm glow intensified over time, and when the entire magic circle lit up, the bright yellow light merged into a continuous radiance.
Standing by the magic circle, Maria, who had reverted to her succubus form, signaled to Haruto and Rias.
