The Final Boss Calls Me Mother

The conference room was vast, its walls gleaming with amethyst. A heavy voice echoed through the space, and a chill settled over the chamber like frost. Ten or so figures sat around the table. At first glance they resembled humans, but anyone from this world would instantly recognize that these beings stood on a completely different plane from mere mortals.

Every one of them had black horns sprouting from their heads. These were the so-called demonkind, and at this moment all their gazes were fixed on the person seated at the head of the table.

The one wearing an expression of clear irritation, as if the entire situation displeased her. A female demon with brown hair and brown eyes. She was one of the five lords who ruled over demonkind and held the position of representative among the high-ranking demons gathered here.

Sena, the black witch.

The oldest-looking man among them spoke again, his voice cold as he addressed the frowning woman who remained stubbornly silent.

“My lord, this is hardly a matter you can simply keep your mouth shut about. Explain yourself clearly. What exactly did you do in that place?”

Though he used polite speech, the question carried an unmistakable tone of accusation. The determination behind his words—that this matter would not be brushed aside—made Sena grit her teeth slightly before she finally opened her mouth.

“I killed them.”

“…Pardon? Killed what?”

“Every last one of the filthy elves who had come to that place.”

“…”

“Haa…”

“…Good heavens…”

Her answer dripped with thick displeasure. Sighs and bitter chuckles rippled through the high-ranking demons seated around the table.

“Those disgusting elves dared to talk back to me. I didn’t like it. So I killed them.”

“Are you seriously saying that right now…”

“Didn’t I already tell you? Just looking at elves makes me want to vomit.”

“…Even so, how could you rip the head off an envoy from another nation?”

“Do you even realize how much damage this incident has caused?”

“Last time you massacred our own troops just because they refused a reckless order… and now this…”

“Please, I’m begging you—just do as you’re told for once. In the end, aren’t we the ones who always have to clean up your mess?”

The high-ranking demons took turns driving their sharp rebukes into her like needles. As Sena listened to their stinging criticism, she could say nothing in return.

Physically, she could have swept every last one of them away without effort. Moreover, she was—nominally, at least—their lord. Considering her temperament, the fact that she had torn off the head of an elf who had dared speak improperly to her meant these people had already earned death more than a hundred times over.

Yet despite all that, Sena could neither talk back nor openly display her anger in front of them.

For one thing, the problem had arisen because she had acted on a whim in the first place. She was also at a disadvantage when it came to verbal sparring. But above all else, the reason she—a former human who had become a demon—had been able to rise to the position of lord was due to their support.

She might hold the upper hand in tangible power, but in intangible influence she could not possibly defeat them. That was what Sena believed. Just as it had been since her childhood.

“Haa… Let’s end things here for today.”

“Please keep this in mind. If something like this happens again, we will not simply let it pass.”

After enduring a long torrent of abuse from the high-ranking demons, the meeting finally came to an end. Dragging her spirit, which felt as if it had been ground to dust, Sena returned to her private mansion. Without even bothering to change her clothes, she began walking deeper inside.

The innermost part of the mansion. After passing through several layers of defensive magic, she finally arrived at a certain room. It was a clean, luxurious space that no one but her was permitted to enter. Sena approached the figure sitting carefully on the ornate bed.

It had the shape of a person… the appearance of a human woman without horns. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Her face was elegantly beautiful, and even at a glance one could tell she possessed a voluptuous figure. She wore the simple clothing of a country wife, utterly out of place in such an extravagant setting.

The woman sat there with a modest, demure air. Sena slowly lowered her head toward her.

“…I’m back.”

Despite the greeting, the figure offered no reply. Even though Sena, a lord, had bowed her head, it maintained its silence. Had it been anything else, she would have torn its limbs apart on the spot.

In fact, the very act of Sena bowing her head was an exceedingly rare occurrence—she who never lowered her head even to those high-ranking demons. Yet despite this rudeness, instead of growing angry, Sena simply drew closer.

“Haaaa…”

She wrapped her arms tightly around the figure’s body and buried her face in its chest. There was no warmth to be felt, nor did it move in the slightest. Even so, this was the moment when Sena felt the deepest comfort she could manage in an entire day of living.

Even if it could speak no words and express no emotions—even if it was nothing more than an empty shell, a failed creation without even a soul, despite all the effort she had poured into making it—this being in the shape of a person was the only existence in this world that Sena could trust with her whole heart.

It was the only thing she could call family.

“Mom… Mom…”

She called the name again and again in a trembling voice. Like a baby seeking comfort, Sena burrowed deeper into the doll mother’s embrace—what was known as the Dutch Mother—and pressed her lips to its cold, massive breast, the one ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠she had prepared in advance.

She did this to soothe, even a little, the mental wounds she had suffered today. To feel, even slightly, the warmth of a mother that she would never be able to experience again.

But then.

“…Sena…?”

“!?”

A twenty-square-meter studio apartment littered with trash. The only light came from the computer monitor; everything else was swallowed in complete darkness.

“Fuck…”

With a short curse, I hurled an empty beer can. It rolled across the floor and landed on a poster, leaving droplets of beer on a smiling face that was now nothing but useless garbage.

-Candidate Choi In-im, People’s Justice Party, District 1.-

It had been ten years since I entered politics, starting as a parliamentary aide with dreams of becoming a true statesman. I had begun from humble origins, but I believed that one day I would rise high enough to change the world. Yet the dream I had poured my youth into for the past decade had now vanished like smoke.

One week before the election, without any warning or foreshadowing, I was suddenly and arbitrarily expelled from the party. The reason given was that I had accepted bribes—something I had never even witnessed, let alone done. Overnight, I was kicked out.

With the election right around the corner, there had been no proper investigation. The expulsion was delivered unilaterally, accompanied only by a cold warning: if I didn’t want to die, I should keep my mouth shut. It took everything from me.

As a city councilor, I had the support of local party members and the public’s favor. Yet this absurd thing had happened for one simple reason—the candidate who replaced me was the son of a famous national assemblyman.

From the beginning, the party had never intended to give me the nomination. My role had been nothing more than fertilizer to help another seed grow. All the effort I had poured into this district, all the work I had done while that parachute bastard hadn’t even shown his face around here, had simply crawled into his fat belly.

Barring some major upset in the polls, his election was all but guaranteed. I had sacrificed every dream, every hope, my entire youth—even love itself—only to lose it all. Alone in the dark, cramped room, my hands shook as I reached for another can of beer.

The liquid inside had gone lukewarm. I popped the tab with trembling fingers. Now that I had lost everything, drinking was the only way I could think of to forget the pain.

That was when it happened.

-Ding.-

A message appeared on my phone. Even through the haze of alcohol, my fingers moved on instinct.

“Pfft.”

A hollow laugh slipped out before I could stop it.

Even though my life as a politician had been insanely busy, I still had one or two hobbies left. One of them was the RPG game Saint Fantasia. It was almost fifteen years old now, a game I had been playing since high school. It felt more like family than a game at this point. I forced my staggering body upright at the sight of the familiar advertisement.

My mind was foggy from drink, but the pain in my heart refused to fade. My political career—no, my entire life—had been completely destroyed by this incident. The dirty feeling was so intense I thought I might go insane. With shaking hands, I turned on the computer.

Thus, in a drunken state, I logged into Saint Fantasia. My mind was half-unhinged, yet my body still remembered the motions. I naturally joined the “Demon Emperor Sena Raid.”

The battle flowed like water. In my first playthrough long ago I had struggled terribly, but now the strategy was engraved in my bones. Without making a single mistake, I brought Sena’s HP to zero in just one hour.

“Aah… Yes… I… I just… wanted to see that person one more time…”

Sena, embracing something that resembled a human woman, was consumed by flames. I already knew from the setting that it was the shell of her “mother,” the one she had tried and failed to resurrect.

A monster who had committed countless massacres, yet in her final moments she showed a human side before disappearing. I had seen the scene so many times that it no longer moved me. Still, the sight of the Demon Emperor Sena turning to ash looked remarkably similar to me—someone who had also lost everything and fallen into ruin.

The difference was that her downfall was the miserable end of a tyrannical monster drunk on personal power, ignoring all justification or politics. It was entirely self-inflicted. In my case, I had done nothing wrong, yet I had been crushed by the filthy realities of politics and left to die.

Either way, we had both met a pathetic end. At least Sena had tasted real power before she died. I hadn’t even gotten a sip, and my life was over. That made me even more pathetic.

“Fuck…”

I had started the game to relieve some stress, but it only made me feel worse. I staggered to my feet, thinking I would at least get a glass of water.

That was when it hit me.

“Ugh!”

A sudden, intense pain stabbed through my chest. It felt as if my heart was being crushed. My body collapsed to the floor. The corner of the bed came into view—the one I had always told myself was dangerous and that I should put something on it, but had kept putting off.

My head struck it exactly.

-Crack!-

There was a short sound, and I felt something shatter. The disgusting sensation of my skull splitting open and my brain being pulverized washed over me. That was how Choi In-im met his death.

In my final moment, unlike Sena who had died at the hero’s hand, I realized I was dying after hitting my head on a bed corner. A bitter feeling washed over me once more.

In the end, my life—the life I had lived chasing the dream of becoming a politician who would change the world—ended in utter misery without leaving behind a single thing.

My consciousness went completely dark. It felt as if I were sinking into a deep, deep swamp. My mind melted away like salt dissolving in water. Memories, emotions, even resentment… everything disappeared together.

But then.

“…Huh?”

The next moment, my scattering consciousness suddenly began to gather again. The fading awareness sharpened, and my vision brightened once more.

-Sluuurp.-

An eerie sound reached my ears, followed by a bizarre sensation. The indescribable, grotesque feeling jolted me, and I quickly pulled my mind together.

Then a figure appeared before my eyes…

‘…Fuck? What the hell is this?’

I almost swore out loud but managed to suppress it with the self-control of a politician. In front of me was an enormous pair of breasts. At a glance, they were one hundred percent female—and quite large at that. Just seeing them would have been enough of a shock for someone who had been a man, but the situation beyond that made me stop thinking entirely for a moment.

A woman was sucking on my breast right now. It was the first person I had seen after waking up, yet I recognized her instantly. After all, she looked exactly like the one I had just defeated before losing consciousness—the Demon Emperor Sena.

‘W-wait… hold on… what is this… what the hell is going on?’

In my confusion, I somehow understood that this was the isekai TS possession I had read about in novels and comics. But even so, how could I ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠be getting my breast sucked—by a fully grown adult woman, no less, and the final boss at that—the moment I possessed this body? What kind of situation was this?

The bizarre feeling of something warm being drawn out of my chest. The ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠sudden fear that if I upset this psychopathic tyrant, my entire body might explode. My mind spun in chaos.

“Se… Sena…?”

I unconsciously called her name in a trembling voice.

Then.

“!”

The Demon Emperor Sena lifted her head. With my nipple still in her mouth, she looked at me. A single clear emotion spread across her face—shock.

My breast milk trickled down from the corner of her lips. The first words that left her mouth were…

“…M… Mom?”
