Take this newly acquired Heavenly Reincarnation Pool, for example.
Even though the system hadn't listed out many specific functions, Sai Akuto had already thought of plenty of ways to use it…
For instance:
First, by using the Heavenly Reincarnation Pool, he could reclaim reincarnation authority for his own faction, allowing him to resurrect his people even before fully conquering a world.
Although its effect overlapped slightly with the Heavenly Rebirth Pool, the true meaning of the Heavenly Reincarnation Pool lay not just in resurrection, but in establishing a complete cycle of reincarnation.
Second, it allowed him to observe reincarnation and the cycle of life and death itself, and study the principles of soul power and resurrection.
The divine power of the Underworld was a force representing death, yet within that death lay the seed of new life. It both complemented and opposed immortal power, essentially functioning as a transformed state reached once power was pushed to the extreme.
The forces within Sai Akuto's own body had merely reached a preliminary equilibrium and cycle, and that alone had already allowed him to break through the barrier of Main God-class. If he could push it further…
At such a time, researching the power of the Underworld was clearly necessary.
To Sai Akuto, it was no more than opening one more window among the dozens already floating in his mental workspace.
…
Thanks to his "Multi-Heart Sense," Sai Akuto could study the Underworld's power without neglecting anything else.
After he guided Irina and Maki through their task, the rest of the original "Church Four" also joined the fray.
From that point on, the Church Four gained a new member in Maki, and successfully upgraded into the "Church Five."
At night, Maki and Irina slept in each other's arms, while Sai Akuto held Maki from the other side, still joined with her as he drifted off.
The next morning, Irina woke up first. Seeing Sai Akuto in the middle, being embraced by her and her mother from both sides, she could only show a helpless yet gentle expression.
From childhood, she had believed herself to be a pitiful child without a father.
But now… it no longer seemed that way.
If her mother had conceived her by heaven's will, then her "father" was the world itself.
She was not some abandoned child. The only reason her mother never told her the full truth was that it was too fantastical, and she'd feared Irina would refuse to believe it.
"Akuto-kun really is a bit of a hentai, huh…"
Glancing at Sai Akuto entwined with Maki, Irina gave a tiny nod.
Her orange twin-tails swayed slightly as she recalled her mother's saintly posture when she prayed before Sai Akuto.
That scene, that level of devotion, had left an exceptionally deep impression on her.
Maki truly deserved the title of Church Saint. In every respect, she stood far above ordinary saints.
"Wait a second…"
Recalling the way Sai Akuto had "sandwiched" two women last night, Irina's beautiful eyes widened slightly.
A thought suddenly occurred to her.
Come to think of it, weren't Griselda and Xenovia also in somewhat of a foster-mother and adoptive-daughter relationship?
Could it be… Akuto-kun really favored that kind of "meal combo"?
"Akuto-kun, you really are a total hentai…"
Remembering the waves of soul-deep shock from last night, Irina's eyes grew a little moist.
Because she had to admit: while Sai Akuto had certainly enjoyed himself, the experience she'd had in both body and soul far surpassed his.
In that sense, she hardly had the right to complain about him.
Pop.
A light sound reached her ears, one she recognized instantly.
She turned around and, sure enough, saw Sai Akuto's handsome face, a faintly playful smile tugging at his lips.
Leaning close to her ear, he spoke softly.
"Irina, judging from your expression, you seem to be savoring last night's memories?"
By now, his Succubus bloodline had evolved to Gold rank, giving him a relatively precise sense of the thoughts of anyone he was in direct contact with.
And since Irina had been hugging him while she was thinking all those things, her every thought just now had flowed straight into Sai Akuto's mind.
As Irina's partner, he felt obligated to help fulfill her wishes, especially when she was too shy to voice them herself.
"…"
Being so cleanly read by him, Irina shrank downward, looking for all the world like she wanted to escape reality.
But since Sai Akuto had already withdrawn from Maki's side and turned toward Irina, her "shrinking down" just meant burrowing straight into his embrace.
"Irina, I really like you like this. Keep it up, okay?"
Sai Akuto slowly put his arms around her and drew her fully into his chest.
Half an hour later, Irina and Maki were once again lying one above, one below, both completely drained under the effects of the bloodline infusion technique.
Their black and flaxen twin-tails intertwined across their bodies.
"Akuto-kun, you really are a hentai…"
Just before she completely blacked out, Irina couldn't help evaluating him again, clearly more fired up than usual.
But she also knew full well that, in this area, her own behavior was even wilder than his.
A "hentai" like her and a "hentai" like Akuto-kun… in a sense, they were a perfect match.
…
That morning, after dealing with the Church Five for the second time, Sai Akuto still got up early.
On the bed, Irina and Maki were still fast asleep, clinging to the drowsy Akeno without the faintest idea of where they were.
Maki's aura was more mature, Irina's more youthful.
Maki's twin-tails were black, Irina's orange. The contrast between them set off each woman's charms to the fullest.
Sai Akuto understood very clearly: the appeal of this kind of pairing lay precisely in the similarity that was never too similar.
Whether it was Akame and Kurome,
Rei and Kiriko,
Saya and Yuriko,
Irina and Maki,
Layla and Sona,
Rias and Venelana, and so on…
All of them carried resemblances, yet each pair retained key differences.
"Come to think of it, every generation of the Gremory heads fits this standard too, doesn't it?"
If Akame and Kurome were "standard edition," then House Gremory was basically the Super Supreme Plus version, the kind that could choke a person with sheer abundance.
In the right time and place, and only when he could completely crush Queen Alice in strength and resolve the whole "Fairy City serial theft case"…
…
After whispering a few words in each girl's ear and saying his goodbyes, Sai Akuto left home.
Today, all preparations were complete. The major matters he'd needed to handle as Grand Chairman had been taken care of.
It was finally time to fulfill the promise he'd made to Akeno.
Outside the Himejima Shrine.
By now, Shuri had already washed and dressed, and had changed back into her familiar shrine maiden outfit in red and white.
"Woom…"
With a flash, Sai Akuto appeared outside the Himejima Shrine.
To give Akeno some time to prepare herself, and to show how seriously he took this, he did not teleport directly to her.
Instead, he walked through the shrine's gate one steady, resolute step at a time, heading toward where Akeno was waiting.
"Akuto-kun!!~"
Noticing his arrival, Akeno sped up and threw herself into his arms.
After drinking in his scent to her heart's content, she finally lifted her head to look at him.
"Akuto-kun, today… my mother will be revived."
"Mm. She will," Sai Akuto nodded.
"I once made a promise with you: to guide this country through a perfect transition toward the form of a Holy Empire."
"That's right," he replied calmly.
"We also promised that, until my mother has fully accepted you, we won't reveal our relationship in front of her."
"So in other words, Akeno, what you're saying is…"
"Since today is the very last chance, Akuto-kun… could you let me engrave your taste completely into my body today?"
"…"
Before he could answer, Akeno rose up on tiptoe and pressed her lips to his.
…
In the light breeze around the shrine, Sai Akuto and Akeno lost all sense of time.
Only after an unknown span did Akeno slowly release her grip from his shoulders.
For some reason, she felt that Sai Akuto had become even more irresistible.
When their lips met, she could feel his pulse and power stronger, more intense than before.
"Mm? This is…?"
Looking up, Akeno noticed that the sky above had been covered in a web of formations.
After receiving Akuto's Evil Piece, her strength had soared from the peak of High-ranked Devil to the peak of Ultimate-class.
After a period of training, she had already stepped into quasi-Maou-class.
But even so, she still couldn't make sense of the formations Sai Akuto had laid across the heavens.
"Resurrection is a serious matter. We don't know what other variables might appear."
"To make sure that, if negotiations with the Underworld gods fail, the battle that follows won't spread and harm the surroundings, we need to set up defensive formations in advance."
In truth, these formations hadn't taken much time to arrange.
Sai Akuto was not distracted enough to be multi-tasking during their kiss.
After inheriting the knowledge of the God of the Bible, his mastery of spellcraft had grown by leaps and bounds.
Now, even though his power had jumped to Main God-class after fusing with sacred artifacts, his foundation in spellcraft could keep up—
In fact, in a very short period, he had already reached a level that outstripped many Main God-class beings in the same tier.
"All right. Preparations are basically complete… so let's begin."
As he spoke, Sai Akuto extended his hand toward the rear of the Himejima Shrine.
"Boom!!"
A shard of bone, smooth and lustrous like jade, burst from a grave behind the shrine and flew straight into his palm.
After her death, Shuri had been buried here.
The bone fragment in Sai Akuto's hand was Shuri's own remains.
