Hello, Type-Moon Universe, I Am Selene

"Your Majesty, Commander Alex reports that they have temporarily captured a leader from one of the territories in this other world…"

"Oh? Temporary capture? Why's that? What's so special about this captive that it warrants a report… This is a minor matter; Alex can handle it as he sees fit," Selene replied, opening her eyes from the lavish lounge chair, a bit puzzled.

From the moment Selene began observing this new world, her interest quickly waned. The Gastrea Virus could do anything Honkai could—and Honkai could do anything the Gastrea Virus could not do. Both could bring war, plague, climate catastrophe.

In short, this world held nothing valuable or interesting for Selene. Its sole worth was as a colony for resources and manpower.

Assigning Alex to independently handle the conquest was a perfect opportunity for honing the Astartes.

"Here's the written report from Commander Alex, which also includes a recorded conversation with one of the leaders, called Seitenshi."

Selene's curiosity perked up slightly as she turned on her side. "Seitenshi? With that kind of title… where exactly did Alex invade?"

Unfamiliar with this particular world beyond "Cursed Children" and the Gastrea Virus, Selene had little knowledge of other details. But the title "Seitenshi" or, in this case, "Holy Son of Heaven," seemed reminiscent of an Eastern rule.

"Where is this Seitenshi located? And why 'temporarily captured'?"

"Your Majesty, she has already taken her own life… According to Commander Alex, she asked that you show mercy to her people," Sebas respectfully replied.

"Oh? She committed suicide—seems she had some grit." Selene opened Alex's report and swiftly skimmed through it.

"So, it's the 'Seitenshi' of Tokyo…" She had no recollection of any such "Holy Son of Heaven," so she continued reading Alex's report.

"Not bad, not bad…"

The report detailed how, after swiftly conquering Tokyo and neutralizing its defenders, most of the First Astartes Legion had landed. Imperial auxiliary forces had also begun to establish order in Tokyo. Alex had gathered intelligence on this world's power structure, discovering human settlements worldwide beyond the Japanese archipelago.

At present, Alex had ordered a division of forces, assigning each Astartes squad led by a company captain to secure their own respective invasion zones…

Selene scribbled a directive—"Proceed as you see fit"—and read on: observations and improvement suggestions.

["Your Majesty, upon conquering Tokyo and other human strongholds, I found numerous abandoned young girls in what these people call the "outer regions." I humbly suggest that these homeless girls might make ideal palace attendants given the grandeur and vastness of Your Majesty's imperial residence.

On another note, the power of Your Majesty's specially crafted Honkai Fusion Detonators is excessively high and needs to be reduced. They should be classified across multiple grades for offense, defense, and yield.

The Vector Jet Thrusters are powerful, but they consume too much energy, limiting sustained operations…

The Astartes Legion lacks high-speed troop transport options, making us overly reliant on Your Majesty's teleportation capabilities for both ground and aerial deployments."]

Nodding, Selene annotated "Reviewed," then continued flipping pages until she reached a recorded video of the dialogue between Alex and Seitenshi.

"Might as well take a look…"

Pressing the purple-red crystal embedded in the file's cover, a luminescent projection flickered to life.

Over the ruined Tokyo City Hall, a frail-looking girl with silver hair and lavender eyes stood dwarfed before the towering figure of an Astartes warrior.

"Accept the Empire's rule, and you shall have the honor to bask in the Empress's glory. Refuse, and today you shall die. What is your choice?" The heavy metallic voice belonged to Alex.

"I refuse. How could a ruler surrender while her subjects still fight and die?" The projection showed the girl's quivering body, though her words held a certain resolute firmness.

"Really? It seems your argument fails to hold. Many of your subjects have already surrendered."

"That was their choice. I wouldn't stop them and would even bless them. But so many soldiers and officials have sacrificed themselves to protect me… I won't betray their loyalty."

…

"Fair enough. But I don't have time to debate with you, false sovereign. Goodbye, false king of another world!" Alex's projection raised his bolter.

"There's no need for Commander Alex to personally act…" Seitenshi's projection coughed blood, staggering as she spoke. "Before I came here, I never intended to live. I will die alongside my loyal retainers. My request to meet you was merely… to ask you to convey a message to your Empress—that they may, although it is a vain hope… please show kindness to those… who have surrendered…"

With that, the slender form of Seitenshi crumpled to the rubble-strewn ground before the towering Astartes warrior.

Click!

Selene shut off the projection, idly flicking the report on the table. "Seitenshi, is it…" Her wish is understood, and I'll consider not killing them, but as for kindness—how far that extends is not certain.

"Sebas, tell Alex I received the message about Seitenshi's last wish and that I agree—at least partially. How he interprets it is up to him." Selene closed the file, her tone casual.

Now that she was Empress, she could afford to leave some ambiguity. Many rulers, past and present, enjoyed being cryptic, so why shouldn't she indulge as well?

It was, after all, "kindness." Compared to a massacre, showing even slight leniency was generous.

But the Seitenshi's fate left her mood subdued once more. Without power, there is no protection, no agency.

Rising, Selene handed the file to Sebas. "Have it duplicated. One for Alex as a response, and one for Dr. Stylish. Let him address the front-line requests for new and improved equipment."

"Yes, Your Majesty!"

Clang—

As Sebas exited the palace, the door closed behind him with a resounding finality, and Selene stood in silence, gazing until the gates shut completely.

"Hah…" Exhaling deeply, she turned toward the detailed plans on her desk. "With administrative tasks complete, it's time to make contact…"

"Not long ago, through the network connecting the world of Akame ga Kill to the Type-Moon Universe, Mine participated in a Grail War—two skilled Lancers, a gathering of three kings…"

Recalling her fragmented knowledge and the information the Type-Moon Universe had transmitted, Selene's eyes narrowed. "It's the Fourth Holy Grail War in Fuyuki."

Closing her eyes again, she projected her consciousness through the stabilized interdimensional path to the Type-Moon Universe. This route was crafted from Mine's dying wish—a desire that Selene had enhanced, strengthening it with vast reserves of spiritual and physical power channeled through the Teigu Shambhala to force open this link.

Using a targeted transmission, the Type-Moon Universe soon detected this strong "will" from beyond.

Thus, the worlds connected. After all, with Type-Moon having numerous heroes in its Throne of Heroes, it was not unprecedented for another unique world to join its pantheon.

"What's this, an invitation?" After an indefinite period, a flood of information suddenly entered Selene's mind, painting alluring images of the Type-Moon Universe—a miracle-filled land with a wish-granting omnipotent machine, endless battles among heroes…

The presentation felt like a desperate sales pitch, drawing Selene toward the path of a Heroic Spirit.

"An olive branch?" she mused. "Did Mine's actions during the Grail War catch the attention of Alaya? Or does Type-Moon Universe want to develop this world as a branch network after receiving my transmission?" Gaia or Alaya…?

In return, Selene carefully tailored her own self-introduction to this new universe…

Instantly, the incoming data stuttered, faltering as if the system had hit a glitch.

Selene understood the cause: based on the information she'd embedded in Mine's mind, she had woven her own accomplishments and the exploits of her subordinates into the message.

She presented herself as the peak synthesis of humanity's potential and divine majesty—a culmination of Type-Moon's most powerful protagonists and godlike figures, tempered and amplified to an impossible degree.

Should she allow the legends of the world of Akame ga Kill to fully enter the Type-Moon Universe, even their counter-forces could find no fault with her status!

To their perspective, the new goddess Selene was something like a celestial manifestation—a divine Empress incarnate, bringing peace to the chaos and uniting a world, reigning with an iron hand as supreme deity.

But now, it seemed Type-Moon's Counter Force was in an awkward position. They had expected this fresh, fictional world to yield a promising hero or two. Instead, they'd inadvertently pulled in something akin to a leviathan!

"Greetings to you, the Counter Force of this new world. I am Selene." Her voice was icy as she opened communications.

"One of my subjects, using an Imperial Arm, escaped death and entered your universe. I apologize, but I request that you return her remaining essence. I am the supreme ruler of my world, and though I respect your dominion here, I do not allow errors within my own sphere of influence!"

"…"

Sensing the flood of information from the other side, Selene continued, tone unyielding. "What do you mean by saying this is her wish, beyond my control? Then I'll retrieve it myself."

"…"

"I see. You'll release her, but only if I compete in this so-called battle for a wish-granting machine and win? You'll also restrict my power, no full manifestation? Don't you fear I'd tear apart the solar system?"

Finally, she'd heard the right words. Masking her satisfaction, Selene nodded coldly after a calculated pause. "Very well, I accept your proposal."

"So, will I enter directly? What level of destructive ability is allowed?"

There was a pause on the other end. They now understood that Selene was no ordinary combatant, but an extinction-level entity capable of devastating worlds—a rare high-dimensional cosmic force within the Type-Moon Universe.

Accordingly, Type-Moon began transmitting the detailed mechanics of the Holy Grail War and its wish-granting powers.

They explained that, in their universe, magic and magecraft were vastly different domains. Magecraft invoked a miracle through abnormal methods and existed within the universe's limits. A mage could call down lightning, create fire, but could not produce anything outside this universe's realm.

Magic, however, transcended all human effort, achieving feats otherwise impossible regardless of resources. Long ago, creating fire may have been a miracle, but after the discovery of fire-starting techniques, it became mere magecraft.

"Understood. So, if my main form doesn't descend, my authority will be constrained by this 'Servant' status, drastically limiting my power?"

"…"

"Hmm, no matter. Even so, I will not lose." She feigned a look of detached arrogance. "Receive my legend…"

Splitting off a portion of her consciousness, Selene unleashed the full might of her legend within Akame ga Kill, allowing Type-Moon to weave it into their Heroic Spirit Throne.

With that, Selene's partial consciousness flowed into the Type-Moon Universe, fully integrated into the Throne of Heroes as a Heroic Spirit. She had finally made her entry.
