-----19+ Warning?-----
Next day.
With the weekend finally here, Issei had already been through a great deal over the past week. The memories of his past life had awakened at last, along with the [Rinnegan] and the [Ten-Tails] that had been set free within him, and then there were his meetings with Rias Gremory and Asia. But above all else, what made him happiest was the progress in his relationship with Rias Gremory! As a healthy high school boy, getting to exchange all sorts of skinship with a beauty like Rias felt like a dream. Of course, compared to the power he now possessed and the fame and dignity he would gain in the future, it was a rather modest dream—but Issei had only been an ordinary high school boy before, and he simply hadn't been able to foresee what was coming.
And so Issei headed to the Church, not to keep watch over the Fallen Angels serving there, but rather to do something indecent.
"Hiding is useless."
By the time he arrived at the Church, the four Fallen Angels with collars around their necks—basically slaves—had all tried to hide at once, but with [detection mode] and those collars on them, escape was impossible. Only then did the Fallen Angels give up, lower their heads with guilty expressions, and appear before Issei.
"You completed everything I ordered, right?"
""Yes, sir!""
"Why do we have to be dragged into this too..."
At Issei's words, Raynare answered with military stiffness, while the other three Fallen Angels were so wronged they were even in tears.
'Still got enough energy to talk, huh? Guess the punishment wasn't harsh enough.'
He said he hated Devils, but he was even more devilish himself. Seriously.
"Then today's task. First, repair everything in this Church that's gotten run-down, and clean every single facility without missing a thing. If you don't finish by today, you know what happens, right?"
""Hiiik!""
"Answer me."
""Yes!""
Issei turned into a villain whenever he stood in front of Fallen Angels, and the fact that they were obeying even without the [Rinnegan] meant his little mini-[Infinite Tsukuyomi] was starting to work. And then—
"Raynare, you come with me."
"...Couldn't we just work together? Please?"
Realizing his intent completely, Raynare reverted to Amano Yuuma and tried to act cute, but—
"Come with me."
"...Yes..."
"Haa, thank goodness."
When Issei glared at her like an ogre, Raynare had no choice but to give up and follow him, and the remaining busty Fallen Angel let out a sigh of relief.
Then he took Raynare through a hidden door in the Church and brought her into a secret room.
"So this got exposed too..."
Seeing the place she had secretly prepared get exposed so easily, Raynare looked utterly defeated.
"I'm going to take a nap here, so until I wake up, massage me here and there."
"Yes..."
"For the record, I said here and there."
Issei had somehow even prepared a bed, and after climbing onto it and settling into sleep mode face-down, he carefully drilled the instruction into her again. Raynare's face went pale.
"Yes..."
In the end, she climbed onto Issei and began gently working his shoulders.
'So she's got a service mindset, huh? Guess the effect of the awakening is starting to show.'
He hadn't told her to climb on top of him, but she did it on her own and started massaging him gently, so his perception of her had definitely begun to change.
'Nice. If this keeps up just a little longer, I'll get my virginity—'
...Someone, please save this hopeless soul. Honestly, the fact that the [Rinnegan] had ended up inside a walking embodiment of lust was already enough to signal the end of the world.
And thanks to Raynare's massage, Issei lost sight of his original goal and drifted into a blissful sleep before he knew it.
"Uuugh... why am I in such a state..."
Raynare's face flushed red with shame.
"But it doesn't feel that bad..."
Somewhere between humiliation and pleasure, the little mini-[Infinite Tsukuyomi] was already blooming steadily, and it seemed her fall was only a matter of time.
Then, as Issei slept with a completely peaceful expression—
"....."
Raynare's little schemes began to stir, and just as she slowly tried to pull her hands away—
"Kyaa!"
Her body suddenly flipped over, and she let out a girlish cry before she could stop herself.
"T-th-this is... I mean..."
Thinking she'd been caught and trying to beg for forgiveness, she was met with—
"Mmm... Rias-senpai~"
He was talking in his sleep. In other words, he had flipped Raynare over while sleep-talking. And then—
"Ahh. T-there!"
After fully lying on top of Raynare's body, one of his hands began kneading her chest.
"W-wow... it's a meeeelon... so soft..."
"Nnh... if you keep touching there... I... I'm going to get weird..."
From a distance, it looked exactly like they were in the middle of something explicit, and the unconscious actions during sleep brought to mind some harem king somewhere who only caused trouble despite having the strongest master in the universe.
"Eh!? Hyoudou Issei? Wait! There!"
Feeling a sudden hand slip into that place, Raynare panicked and hurriedly tried to pull Hyoudou Issei away, but because his body had been unconsciously reinforced by chakra, he didn't budge at all.
"Wait! Nnngh... kyaaa!!"
When it went all the way in, Raynare screamed.
"Aaaah! This round, I'm winning no matter what!"
This time, Issei was dreaming about a game and moving his hands however he liked...
From here on, we cannot show you any more, so this part will be censored.

"Haa... haa... haa... I... I can't get married anymore..."
Raynare, drenched in sweat and utterly spent after being dragged into irresistible pleasure, collapsed beside Issei and fell asleep from exhaustion. (Issei had merely touched melons and played games in his dream.)
Then Issei woke up.
"This is..."
Seeing the damp sheets and Raynare sleeping like a girl, soaked in sweat, he frowned.
"What the hell happened here..."
He really had to start suspecting that Hyoudou Issei might be harboring the soul of some harem king from another world.
.

.
After finishing Raynare's "training," Issei left her there, still asleep from exhaustion, and stepped outside.
"...Fast."
"I-I completed everything! Issei-sama!"
The Church had become so spotless it looked like a brand-new building. For ordinary humans, that would have been impossible, but for Fallen Angels who used magic, it wasn't that difficult. They stood before Issei with proud expressions, like puppies desperate for praise.
'These guys... I should make them do something even harsher.'
His original goal hadn't been repairs, but draining their stamina so his genjutsu would work better. Yet they were unexpectedly energetic, so the corner of his mouth lifted again into a wicked smile.
"Then the next task is—"
"Th-there's more?"
"Nooo~. I want to take a bath and rest now~"
The busty Fallen Angel, who had thought this was finally over and was hoping to rest, went pale, while the loli Fallen Angel tried to act cute and complain. But when she saw the target mark appear on Issei's forehead—
""Hiiik! A-anything you say!!""
'Looks like the effect is showing.'
"Come to think of it, this Church feels a little cramped."
"....."
"....."
"....."
At Issei's words, the three of them practically lost their minds.
"You know what I mean, right? Ask Asia about the interior design and get it sorted out."
He was smiling as he spoke, but it wasn't a smile. The chakra he was pouring out was basically a warning that if they failed to complete it, it would be over for them that day. In the end, the Fallen Angels burst into tears and got to work, and from that day on, no one ever saw them resting again.
And so Issei, who had effectively gained four slaves—no, four Fallen Angels—said,
"Asia, want some tea?"
"Yes!"
and decided to enjoy tea with Asia, completely unaware of the danger heading his way after taking those four Fallen Angels into his hands.
Meanwhile, while Issei was chatting away with Asia—
At Kuoh Academy's old school building, Rias Gremory had come to school even on the weekend and was drinking tea while reading a mountain of books in the clubroom.
"Ninjutsu..."
Ever since hearing that shocking truth from Issei the previous night, she had begun investigating it. An unknown power that even she and the other Devils had never known about—perhaps a force that could determine their fate, one that might destroy them or revive them. She searched through every source she could find, but not even the tiniest scrap of information turned up.
"As expected, that power must be some kind of mythology. Otherwise..."
In this world, there were many factions besides the Three Factions. The Norse myth of Asgard, the Greek myth of Olympus, and countless other mythologies across the world all existed as powers in the world where Issei lived. So if something didn't appear in human history, she assumed it must belong to some unknown mythology. And as she worked beside her, her vice president Akeno said—
"I understand it's a power that can do many things, just as the president said, but should we really believe that boy's words as they are? Isn't this a waste of time?"
Unlike Rias, Akeno was suspicious of Issei beneath her pure smile. She was helping with the work because Rias had asked her to, but the sudden appearance of Issei and his claims had left her uneasy.
"I've thought about that too. But if there's even a chance it's true, we need to prepare in advance or we won't know what might happen. And even if it's a lie, I've always been interested in mythology and history, so I think it's fine to treat this as simple study, don't you?"
"If the president says so."
At Rias's words, Akeno obediently accepted her decision and continued working. Then, suddenly, a magic circle appeared at the entrance.
"Lady Rias, it's been a while."
"Grayfia?"
A silver-haired maid stepped out. And as if something had come to mind the moment she appeared, Rias's expression darkened.
"Young lady, I've come to deliver the head of the house's message."
