I think i Forgot to say..
But Saki is not In the Harem and she is also not part of "Metamorphosis" since Saki is older....meaning DxD does not share worlds with it.
If it did leo would've burned it down.
But tell me do you want a chapter of How ishtar got here ... like the journey of Saki becoming a history teacher.
I have funny interactions planned with her like Barging into Yomi after daki begged ishtar to revive the train driver.
Saki is more like.... turbo granny as a cat and will be useful when Ishtar is out.

Tiamat watched as Nammu finally broke down, letting out all the regret and sorrow that had been eating away at her for so long.
She let her daughter have this moment—this long-overdue release—before turning her gaze to her grandson.
He had finally calmed down, though his sheer presence still weighed heavily on the space around them.
But more than anything, she was proud.
Proud of Nammu for finally letting go of the chains that had bound her heart.... of the strength it took to face her mistakes.
Though they were pretty stupid..
And, of course… happy that she now had an absolutely adorable grandson.
But that was beside the point.
A small smile tugged at her lips as she extended her authority.
For some time now, she had been spreading the Sea of Life in vapor form, letting it subtly seep into the space around them.
With a thought, she invoked Cellular Compulsion, forming a geis at the very foundation of her grandson's being.
Unlike the beasts she had created from the Sea of Life, this was different—this was more refined.
His massive body trembled, shuddering as if struggling against an unseen force.
But Tiamat was gentle, guiding the change rather than forcing it.
His form shrank, collapsing inward, shifting, condensing—until finally, he floated before her.
A small boy.
His hair was a deep, mesmerizing blue, his eyes large and impossibly innocent, staring up at her with a confused yet curious expression.
Ten small horns crowned his head.
Tiamat grinned, hands on her hips as she admired her work.
"Much better."
She crouched down, cupping his cheeks, marveling at how soft and warm he was.
"Oh, you are adorable," she cooed, already imagining all the ways she was going to spoil him.
Her grandson blinked, tilting his head as if unsure of what just happened.
Nammu, still emotionally sensitive, could only watch in stunned silence.
Tiamat chuckled.
"Well, someone's going to be the most spoiled grandchild in the universe."

Aizen reappeared in the depths of Muken with a faint blue glow, the same abyss where he had been sealed for countless years—the same place where he had once departed on his journey to another world.
The difference now?
His bindings were gone.
Aizen ran a hand through his hair, exhaling slowly.
His posture relaxed, but there was a sharpness in his gaze, something deeply unsettled beneath his composed exterior.
He smirked, but it lacked his usual amusement.
Instead, there was unease… and something he hadn't felt in a long, long time.
"Leo..." he murmured to himself. "You are a formidable force."
He had been uneasy ever since he laid eyes on that man.
Aizen had encountered many powerful beings.
He had faced power like Almighty.
But Leo?
Leo was different.
Leo talked with an ease that was almost disarming, much like himself in the past, his tone friendly, even playful at times.
Yet despite this relaxed facade, there was something beneath the surface—something that gnawed at Aizen's instincts.
He had never felt like this before.
It wasn't just raw power—no, in that regard, Tiamat overshadowed even him.
But Leo was dangerous in a way that transcended simple strength.
There were no limits to him, no defined peak, no preordained fate guiding his hand.
He was, in every sense of the word, unbound.
And that was terrifying.
"The One True Satan..." Aizen muttered, the words filled with something deeper than just acknowledgment.
A title meant to inspire fear, respect, and dominance.
The way concepts bent around him, the casual ease with which he manipulated forces beyond comprehension, the sheer conceptual weight he carried—this was no mere claim of dominion.
Leo was not someone striving toward godhood.
Like he once did...
He was something that even "gods" had no answer for.
"This is what it truly means to be 'Satan,' isn't it?" Aizen mused.
"Not a ruler of devils. Not a title for the strongest among them.... But the defiance of all order itself. The rejection of limitations. .....The refusal to be bound by the laws that shape existence for else."
He laughed, an amused, almost exhilarated sound.
"A being like that... It makes me truly afraid "
Aizen had always believed in control.
In knowing every variable, in bending every force to his will....acting like god among the less intelligent.
But how do you control something that cannot be defined?
How do you predict the movements of a being that exists beyond limitations?
He clenched his fist, feeling the unrestricted surge of his power, the absolute freedom he had sought for so long.
And yet, even now, as he stood unshackled, truly free—
He couldn't shake the feeling that compared to Leo, he had never known True Freedom.
Aizen looked up, his eyes tracing the abyss above him.
This prison—Muken—had been redesigned for one sole purpose.
To bind him much like Yhwach ,into a state of being a lynchpin.
In the eyes of the Soul Society, Aizen alone was a threat great enough to justify its existence.
And perhaps, for a time, they were right.
Ever since that day, when he enacted a sacrificial Kido, consuming essence of every prisoner within these depths in a final attempt to escape—he had believed he could break free.
Not for himself, but to aid Kurosaki.
Aizen had seen something in that boy.
A spark of potential that should never have been snuffed out so early.
He couldn't bear the thought of a being like Ichigo—someone who could truly stand beside him—perishing before realizing his full strength.
But in the end… He was too late.
Ichigo Kurosaki, a soul meant to ascend beyond the limits of mere existence, was gone.
And Aizen?
He had slaughtered all of Hell for it.
Every single wretched being within its depths had fallen to him, fueling his ascension, forcing him to evolve even when he no longer wished for it.
His Zanpakutō, long since fused with his very being, reached a state beyond what a 'Bankai' could define.
It wasn't really a "Bankai" since it was his dormant state now.
It was more like .... He had broadened his perspective.
And yet, even after reaching that pinnacle…
He willingly returned to Muken.
Not out of defeat.
Not out of submission.
But because, in that moment, he realized something terrifying— He was truly alone.
At the peak of power, standing above all, he had no equal.
No rival.
No purpose.
There was nothing left to reach for, nothing left to achieve.
The vast emptiness of supremacy had hollowed him out more than any blade ever could.
It was then that his ambition died.
And with it, the Hōgyoku became dormant—its pulse, once entwined with his will, fading into silence.
For the first time in centuries, Aizen had nothing to achieve.
But now?
He placed a hand over his chest, feeling it—truly feeling it.
A rhythmic, steady beat, surging through him like a quiet storm.
Thump.
A heartbeat-His heartbeat.
That emptiness, that abyss of nothingness where his drive once resided—was stirring again.
"How amusing..." he murmured to himself, lips curling into a slow smirk.
Leo... You have reignited my ambition.
He laughed, a deep, quiet sound that echoed in the emptiness of Muken.
It wasn't amusement, nor arrogance.
It was exhilaration.
For the first time since that day—Sousuke Aizen was hungry again.
Aizen muttered softly, "Zoltrak."
A beam of pure destruction erupted from his finger, tearing through everything above him.
Gone.
The endless dark of Muken, the seals meant to bind him, the layers of Kido suppressing his power—all erased in an instant.

Leo sat quietly, watching as Nammu played with her son—Elum, a name derived from ancient Sumerian, meaning Salvation.
The boy, small yet unmistakably powerful, laughed as his mother chased him, his horns gleaming under the soft light.
Leo tried to keep his expression neutral, but his current position made that difficult.
Tiamat had wrapped herself around him, her legs snugly positioned around him and him sirting in between them.
The moment Nammu had taken Elum from her arms, she had latched onto Leo instead, all while justifying it with a smirk.
"I was in mother mode, and you disturbed me," she had said, as if that explained anything. "So, you'll have to take responsibility now, Leo."
At first, she simply patted his head, her hand threading lazily through his hair. But gradually, her hand had begun to wander, fingertips grazing beneath his shirt, warm against his skin.
Slow. Teasing.
Leo sighed internally.
She's definitely slipping out of "mother mode" — which was definitely bullshit..
Then, his thoughts drifted—back to something that had been weighing on his mind.
Something he hadn't voiced.
And before he could stop himself, the word nearly escaped.
"Mo—"
Only the first syllable left his mouth before he caught it.
His expression hardened, he locked in, his voice shifting mid-sentence, regaining its usual authority.
"Tiamat."
Her fingers halted against his skin.
His eyes met hers, firm and unwavering.
"We need to talk."
Tiamat tilted her head, curiosity flickering in her gaze.
The teasing amusement in her smile faded slightly.
She could tell—Leo wasn't joking.
