The Defeated Hero Becomes a Woman
"Turns out, the strongest hero in history ends up like this?"
Even the casual words sent a shiver of pressure through the air.
The pain from countless clashes earlier had left my body aching, and blood rose in my throat.
"Cough...!"
"Hero! Are you okay?"
The hero, Brien, looked back with great effort.
Thanks to him blocking almost all of the Demon King's terrifying attack, the others in the party were in relatively good shape.
The magician, the archer, the cleric.
The precious comrades who had always supported him from behind during his rampage, but their power had never reached the Demon King.
The Demon King was far ahead in knowledge of magic.
The arrows shot by the archer spun in circles and flew toward the hero.
The cleric had been unable to heal the Demon King's wounds.
Even the hero himself was in this state from attacks the Demon King had casually launched... it was clear there was no chance of victory.
Then, how should he act?
The hero's judgment, which had never given up and had crossed countless lines of death, was cold and precise.
*I will sacrifice myself.*
It was the only choice, since only he could leave even a scratch on that Demon King.
While the hero bought time, the other two had to take the Holy Sword and escape with the symbol of hope.
The four members of the Hero's Party were connected by telepathy magic.
Brien prayed that even this magic had gone unnoticed by the Demon King and calmly explained his final plan.
[...Got it?]
[No way! That's impossible, Brien! We were supposed to return together!]
The magician, who had been especially close to him, had almost screamed in refusal, but it was clear that the hero's judgment was the only opening.
[If I stall longer, the Demon Army's reinforcements might arrive. This is the optimal time to flee...]
[The Lord, Lord, and I will never forget your noble sacrifice.]
Listening to the answers from the archer and cleric, Brien smiled faintly.
[When I count to three, I'll throw the Holy Sword behind me and run immediately.]
Brien braced his wobbling legs and stood up, gripping the Holy Sword tightly.
[Three.]
He immediately crouched down as if about to charge again, locking eyes with the Demon King as if he would pierce him with his gaze.
[Two.]
The Demon King watched the scene with a ridiculous expression and raised a single finger.
Dark red magic, as if boiling, gathered at the tip.
"**One! Run!**"
Brien swung his arm with all his strength.
The direction his arm pointed was backward.
The radiant Holy Sword flew in the opposite direction from the Demon King.
At the moment Brien kicked off the ground with his bare hand, which was gathering magic power, the Demon King fired the magic from the tip of his own hand at the hero.
The horrifying scream the archer had let out upon catching the Holy Sword was swallowed by the magic explosion that erupted with a deafening roar...
**Krrrrr...**
The Demon King's Castle, which had been shaking for a while, finally fell silent.
Even though it was an explosion at the level of 9th-rank magic by human standards, every single piece of furniture in the Demon King's Chamber remained intact.
The only thing damaged was the hero who had just arrived today.
"Have the others escaped?"
The Demon King's question fell, and black mist gathered from the right side of the Demon King, slowly taking form.
In an instant, an elderly demon butler in a luxurious black suit and monocle appeared, replying with polite respect.
"It appears he used teleportation magic. Estimated rank is..."
"Stop. I don't care."
The Demon King's gaze remained fixed on the hero.
The butler, sensing the gaze, lifted his monocle and looked at the fallen hero.
Surprisingly, the hero was still alive even in the middle of the explosion.
He hadn't even lost consciousness.
With his face twisted in agony, the corners of his mouth were slightly raised.
*'He escaped safely...'
The mission was accomplished.*
Brien exhaled a breath mixed with laughter and coughing.
Well, it had been worth it anyway.
Lying half-collapsed, the Demon King's voice reached his ears.
"Bring him here."
"Yes."
Along with the answer of some unknown person, Brien's body rose into the air.
His lying body slowly turned upright and became fixed standing.
In that state, Brien floated all the way in front of the Demon King.
"What's so fun about that?"
"I have no words to answer you. Kill him."
"Why should I listen to you?"
Brien kept his mouth shut.
He just glared at the Demon King with rebellious eyes.
If he had even a little more strength in his body, he would have spat saliva.
But now, even using that much strength was difficult.
"Hmm. You are quite rebellious, aren't you, Your Majesty."
"You were the one who said the other side fits better, didn't you?"
"...Shall I prepare?"
"Do as you like."
What the hell were they talking about?
But seeing the situation, it didn't seem like they would kill him right away.
*'Why did they save me? Are they going to do some kind of human experiment on me?'
If they experiment on the strongest human, the hero, they would gain something from it.'
*'Still, I'm not going to quietly accept it however they want.*
If they save me, I will definitely drive a dagger into their Demon Army's hearts.
As he floated along behind the butler, Brien made that vow over and over again.
The place Brien arrived at was quite a spacious room.
It seemed like a woman's room, and the dishes and various furniture were elegant and luxurious.
An oddly large bed was attached to the wall on one side of the room.
A sinister premonition crept up slowly.
"Where is this place?"
The butler didn't even pretend to hear.
He laid Brien down on the vast bed and muttered some unknown magic.
All Brien could see was the back of the butler and the tail hanging below his waist.
"What the hell are you doing...!"
Brien's voice echoed hollowly.
The butler acted as if Brien didn't exist and continued his work.
He looked back at Brien about ten minutes later.
In one hand, he held a glowing pink sphere, which clashed horribly with his uniform black attire.
The butler approached Brien slowly with a straight gait.
Somehow, that figure felt like a blade on the guillotine.
It wasn't magic of any normal kind, no matter how you looked at it.
Brien tried to move his body in various ways and shouted at the top of his lungs.
"S-Stop! Just kill me! Don't do those weird things, just kill me already!"
He resisted while enduring the pain, but there was no emotion in the butler's eyes.
He approached like a machine and tore off Brien's tattered clothes.
His belly and crotch, covered in wounds, were exposed.
"You bastard, what the hell are you doing... Gaaah!"
Brien cursed in bewilderment, but the butler didn't hesitate and stuffed pink magic into Brien's lower abdomen.
An indescribable sensation surged through his entire body, and Brien rolled his eyes and began to gasp for breath.
It was hot. No, it was freezing cold, but then hot again.
What the hell is this?
Ugh... Hah... Hah.
Why is my breathing so tight?
My vision was white and my head was spinning.
I was breathing shallowly and quickly like an instinct.
For some reason, I had to do it that way.
The pain that had been felt throughout my body since the Demon King attacked was long gone.
Instead, a strange heat kept coming from my lower abdomen.
"This... What is this..."
It was clear that his ears had changed too.
His own voice coming out of his mouth sounded strange.
"You recovered consciousness so quickly. You truly have talent. The Demon King's eye is accurate, as always."
The butler's voice echoed.
Huh? Why is the author's voice normal?
Just as I had faint awareness, the butler's voice rang out again.
"I'll just do a quick check before His Majesty arrives."
There was no time to ask what kind of check—
The sensation Brien had never felt before began from his crotch and pierced through his entire body.
"Hiiiiaaaaaah?!"
Should I say it was thrilling, or ringing?
The sensation of his whole body going numb made Brien tremble.
*'W-Wait, this is dangerous...!'
A sudden rejection surged up.
But Brien didn't know.
That below his waist, it was twitching as if wanting that sensation even more.
Next was his chest.
The butler slightly bent his waist to meet Brien's eyes and placed his hand on the center of his chest and the nipple.
Brien let out another scream in amusement.
"Hiiick!"
At the same time, he realized.
It was impossible to avoid it.
The position of the nipple was completely different from what Brien remembered.
Even the butler grabbed the tip of Brien's nipple and slightly lifted it.
As if to show it off.
As if to engrave the plump breasts clearly into his eyes.
"You... You bastards, what the hell are you doing to my body... Gah. What are you doing...!"
He had become a woman.
The first sensation he had felt was probably in his vagina.
Tears streamed down his face from shame.
"I will never kill you neatly. Until you all beg me to die, I will crush you to death!"
The words, spoken harshly, somehow came out pitifully and cutely.
When the words ended, the butler's hand touched Brien's thigh, and another groan escaped.
With such a weak body.
Brien's heart was sinking deeper into the abyss of despair.
"The transformation is progressing well."
Brien's voice, filled with lost light and tears, reached his ears with the Demon King's cursed voice.
He, no, she began to writhe her body again.
Only then did he realize.
Unlike before, his wrists and ankles were now fixed.

"You bastards, let me go and turn me back into my original form...!"
The Demon King and the butler calmly discussed the Brien who was causing a ruckus on the bed.
"Yes. As you can see, the suitability is the highest."
"Good. Then I'll leave. I'll leave him to you from now on."
"Long live the glory of the Demon King."
With a creaking sound, the door closed.
And the Demon King climbed onto the bed where Brien was tied.
"You, this bastard, don't tell me...!"
"Your mouth is still rough. What does it matter. I'll explain from now on. Who is on top, who is on bottom."
The Demon King slowly approached.
The clothes he was wearing slowly turned into mist and dispersed...
The muscular body and the viciously erect penis came into view.
The Demon King proudly displayed his body and smiled sinisterly.
"Provisional Contract. Shall we start now?"
