When the final mission was completed, a quiet notification echoed within their minds.
Seven days remaining before return. A full week.
Normally, it would be enough time for them to relax and spend time with the friends they've made in this world before returning home.
But for Yuuji, with everything he had on his plate, it was very short.
There were responsibilities he could not ignore. Promises he needed to keep. And people, important people he wanted to spend time with before the inevitable departure. He had no way of knowing when he would next return to this world… or if circumstances would allow it so easily again.
The others understood.
So, with the discreet assistance of Sona and Rias, arrangements were made. Leave requests for the school were handled smoothly, and with the acknowledgement of the director, who worked for Rias's family, they were accepted easily. For one week, Yuuji and the members of the Multiverse Group Chat who attend Kuoh Academy were "absent" from school.
During these seven days, Satoru Suzuki chose to travel alone and enjoy things that had only been possible in Yggdrasil and nowhere else.
Kyoto, Yakushima, Miyazaki, Kurobe, Hokkaido—he explored as many natural attractions in Japan at an unhurried pace. Then midweek, he teleported to Gero in Gifu Prefecture, famous for its hot springs. There, beneath rising steam and mountain air, he allowed himself rare stillness. No battle preparations. No pollution. No work.
Just warmth.
Tatsuya and Lelouch approached the week more practically.
They spent a day traversing Tokyo's shopping districts, searching for gifts for Miyuki, Nunnally, and Shirley. The process proved… unexpectedly difficult.
"What do girls actually want?"
Lelouch had muttered at one point.
Tatsuya had offered no helpful answer.
Their purchases were ultimately simple. Necklaces, hair pins, phone straps, and various snacks and delicacies they think the girls would love and store them in their Multiverse Group Chat Inventory for preservation.
Once finished, neither felt particularly inclined to continue wandering aimlessly. The remainder of their week was spent in quiet comfort—sometimes at the estate, sometimes within the suspended serenity of the Hanging Gardens. Strategy discussions faded into casual conversation. For once, they allowed themselves to simply exist.
Aika, Erika, Albedo, C.C., Semiramis, and Xenovia, on the other hand, embraced the week wholeheartedly.
With Rias, Akeno, Kuroka, and Koneko acting as guides, they toured Tokyo's bustling districts, Kyoto's historic temples, and Osaka's vibrant streets. Ancient shrines. Modern skylines. Street food stalls. Hidden cafés.
Teleportation made distance irrelevant. What would normally take hours became moments. They could enjoy Kyoto in the morning, Osaka in the afternoon, and return to Tokyo by evening without fatigue.
And at night—
They would summon Yuuji.
No matter where he was, no matter how busy his day had been, he would feel the familiar tug—and appear beside them. They would walk illuminated streets together, share quiet meals, watch city lights from rooftops, or simply sit close in companionable silence.
They would have preferred him with them from the very beginning.
But for the first few days of that week, Yuuji had unfinished work.
Work of divine scale at the Heart of Heaven.
Deep within Heaven's core, where divine law intertwined with reality itself, Yuuji worked alongside Michael and Uriel.
Gabriel would remain nearby—sometimes observing in silence, sometimes bringing refreshments during their breaks, her presence gentle and warm.
The vast mechanisms of Heaven's system—once fractured and unmanageable after the death of the Biblical God—were gradually being rewritten and stabilized under Yuuji's guidance.
But Yuuji didn't simply "fix" it. With the Seraph's acknowledgement, he helped adjust the system to be more compatible with the current situation of the world.
The restored system would now allow angels to form families with humans—so long as their bond was founded upon genuine love and both possessed virtuous hearts. No coercion. No corruption. Only sincere, genuine devotion and loyalty. And they will be protected by Heaven's will itself if they were to be in harm's way.
He also offered Michael insight into a new framework—one that would allow exceptional humans to ascend as half-angels under Heaven's authority, paralleling the Devils' Peerage system but without its exploitative aspects.
Saints and Saintesses would once again be born into the world.
Children blessed at birth with innate divine protection. Souls inclined toward kindness, compassion, and unwavering goodness. Upon their arrival into the world, Heaven would be notified. Gabriel herself volunteered to guide them—nurturing them into stewards of faith, quiet lights who would guide humanity not through domination, but example.
The system extended further still.
Those bound by genuine fate would find miracles coming to them more readily. Not blatant divine interventions—but subtle shifts. Fortunate coincidences. Narrow escapes. Unexpected aid. Their karma would act as a shield against malicious forces.
Prayers born from true desperation and sincerity would no longer vanish into silence. The system would respond—gently, invisibly—guiding help their way.
And those who invoked God's name for greed, manipulation, or cruelty?
Calamity would follow them. Not arbitrary punishment—but the natural consequence of twisting divine will.
Balanced. A world of just.
With the missions behind him, Yuuji's focus sharpened to an extraordinary degree. Progress accelerated at a pace that left even Michael momentarily speechless.
"Your efficiency is… astonishing."
Michael admitted once, genuine awe in his voice.
By the end of the fifth day, the majority of the restoration was complete. Only a handful of delicate adjustments remained—matters internal to Heaven that required Michael's authority and oversight.
Satisfied, Yuuji stepped back and entrusted the final touches to him.
Michael's gratitude was sincere and profound. Heaven's foundation was no longer crumbling. In some ways, given the world's new balance between factions, it functioned better than it ever had.
But not everyone felt entirely at peace.
Gabriel walked him to the threshold of Heaven.
Her hands clasped gently in front of her. Her golden eyes shimmered faintly.
"Yuuji-sama…" she began softly.
He paused. She looked up at him, lashes damp, expression fragile in a way only she could manage.
"Would you please stay in Heaven a little longer…? Just a bit more…? Please?"
The plea was quiet. Earnest. Those downturned, glistening eyes made refusal extraordinarily difficult.
Yuuji hesitated.
He could feel her sincerity. Her attachment.
But he also had others waiting for him.
"Gabriel… I'm sorry."
After patient reassurance, gentle words, and a promise—spoken with unwavering certainty—that he would return, Gabriel finally nodded.
Reluctantly.
"Then… I will wait."
She whispered.
Only once she smiled again—though faintly—did Yuuji allow himself to depart.
In a shimmer of light, he returned home.
On the sixth day, Yuuji set everything aside.
No multiversal missions. No looming farewells. No business responsibilities.
He spent the entire day with his lovers, including Xenovia, Kuroka, Koneko, cherishing the simple warmth of their presence. Together, they traveled to Hakone, where the air was crisp and clean, carrying the faint scent of pine and mineral-rich steam.
They relaxed in an open-air hot spring, the waters gently lapping against smooth stone as mist curled lazily into the sky. Before them stood Mount Fuji in quiet majesty, its snow-capped peak glowing softly beneath the golden afternoon sun.
There were no grand declarations that day. No heavy conversations. Just laughter. Just warmth. Just the soft splashing of water and the comfort of bodies leaning against his.
For a little while, the ticking clock did not exist.
On the morning of the seventh—and final—day, Yuuji and the other members of the Group Chat gathered in the estate's main living room.
The space was quiet, sunlight filtering gently through wide windows and casting long beams across the polished wooden floor. They sat around the long wooden table, their expressions calm but thoughtful. There was an unspoken weight in the air.
The sliding door eventually opened with a soft shhhk, revealing five familiar figures.
"Yuuji? You called…?"
"Ara, everyone is here as well."
"Nya?"
"…"
Rias, Akeno, Kuroka, Koneko, and Xenovia stepped inside, clearly surprised. They had expected a private conversation with Yuuji—not a full gathering.
Dressed casually in loosely tied yukata, their hair relaxed and unstyled, they looked more at ease than usual. They didn't expect a serious conversation.
"Ah, you're here." Yuuji said gently.
"Please, take a seat."
"Hehe~ Come and sit, girls! There's something we want to tell you!"
Aika chimed, patting the cushion beside her. Still confused but trusting, they took their seats.
Kuroka tilted her head, tails swaying lightly.
"What do you want to talk about, nya?"
All five of them turned toward Yuuji.
As agreed beforehand, he would speak for everyone to them since he was the one closest to them.
He took a quiet breath.
"We want to tell you about us… Our truth. Our origin."
The atmosphere shifted.
They had always been curious. Of course they had. Yuuji and the others were extraordinary—far beyond even the most powerful beings of their world. But they had never pried. They trusted him enough to wait.
And now, it seemed the time had come.
"Everything I say from here on will be the truth." Yuuji continued.
"It may sound absurd. Unreal. But I promise you—it is all real."
Their hearts beat a little faster.
They believed him. But the way he framed it made their stomachs tighten with anticipation.
"Firstly… We are not of this world."
Silence.
The words landed like a stone dropped into still water.
Shock froze their expressions—but before they could react, Yuuji continued.
He told them everything.
About the different worlds they came from. About their original "stories." About the Multiverse Group Chat. The missions. The way their world had once unfolded before their arrival.
And finally—about High School DxD.
When he projected the anime onto the supercomputer screen, the room fell into stunned silence.
They watched. They watched versions of themselves move, speak, struggle.
The story was not identical—because Yuuji and the others had changed it—but everything before their appearance was unmistakable. The same personalities. The same relationships. The same turning points.
It was them.
Or rather… it was what they would have been, if they had never come.
"This is…" Rias exhaled slowly, pressing her fingers to the bridge of her nose.
"This is hard to process."
Akeno's usual smile had faded into something thoughtful and quiet. Koneko stared at the screen as though trying to reconcile two realities. Xenovia's brows were knit together in intense contemplation.
Even Kuroka—normally playful—was silent.
"Well, it's not your fault. " Erika said gently with a shrug.
"It's a lot to take in."
"Yuuji-sama… Master…"
Xenovia looked at him, then at Erika—the two people she respected most. Her voice wavered slightly, not from doubt—but from shock, disbelief, and awe.
Kuroka, however, recovered first.
"It's hard to believe… but it's still very interesting, nya!" Her golden eyes sparkled, tails swishing excitedly.
"Yuuji-nya! Did you know about my past from the anime too?"
"It wasn't explained explicitly. At least not fully. But I had suspicions. So I investigated."
Kuroka's ears perked.
"Ah, Yuuji-nya~! I love you!!!"
She leapt into his arms, rubbing her cheek against his chest as he chuckled softly and stroked her hair.
Koneko stared at him, stunned—then her expression softened into quiet gratitude.
He had learned about her sister's and her suffering not because he was told. But because he cared enough to look.
"Yuuji… you mentioned missions." Akeno said, her tone calm but serious.
"What kind of missions?"
He explained them one by one.
Defeating ten stray devils. Defeating high-class or stronger devils. Sacred Gear users. Kokabiel. Ensuring the success of the Tri-Summit. The Old Satan Faction.
Rizevim.
The more he spoke, the heavier the atmosphere became.
Rias felt a chill run down her spine.
Each of those tasks… any one of them could have spelled disaster for her peerage. For the Underworld. For the world itself.
And they had handled them. Calmly. Successfully.
"I…" Rias swallowed.
"I can't even imagine accomplishing something like that."
Only Yuuji and the others could have done it so cleanly. So decisively.
"And after completing the missions, we get to invite one person from this world to join the Group Chat~!"
Aika added brightly, breaking the tension.
That statement stunned them all over again.
Another world. Traveling between universes. Opening a door to a new reality. Realities.
The concept alone was overwhelming.
Yuuji nodded slowly, then he turned toward Rias.
His gaze was steady—but gentle.
"That's right."
He said softly.
"Rias… would you like to join us?"
