The Shut-In Prince’s Splendid Social Debut — Me, a Villainous Imperial, Have Spent the Last Fifteen Years Fighting the “Wicked Thoughts” Eating Away at My Mind. When I Finally Returned to High Society, There Were Way Too Many People I Didn’t Recognize

◇◇◇◇

Fifteen years have passed since I reincarnated.

This world is finished.

To understand that, fifteen years was arguably too long a time.

“Evil Red Thrones”

Abbreviated as—ERT.

The world I reincarnated into was the world of a certain multi-ending RPG that took the world by storm in my previous life.

A truly bloody world where, triggered by the death of the “Sovereign Unifier” a war among seven kingdoms begins over the single, bloodstained “Throne of the Conqueror.”

The one who creates the trigger for that conflict is the third son, the Third Prince Yoan Joachim Rodenze. In other words, me.

Simply put, the root of all evil.

A gruesome villain who thoroughly disparages his family and relatives, beheads a certain heroine’s father, and even goes so far as to send that head to her.

In the main route, he is repelled by the protagonist and exits the stage in the mid-game after being made to drink a poisoned cup.

The scene where he is poisoned at the marriage ceremony was quite a spectacle.

Clatter, he drops the silver cup, rolls around the floor unsightly, and dies with a pale face.

From a player’s perspective, it was a satisfying development of karmic justice, but when it actually befalls oneself, it is unbearable.

Occasionally, there was a saying that “Villains are not evil from birth.”

I used to think so too, but unfortunately, born villains do exist.

——Yoan is one. I realized it after reincarnating.

Every time I meet people, thoughts like “Slap them” or “Punch them in the nose” flow in, regardless of gender.

Even when I am alone, some kind of obsessive compulsion surges like a raging wave, saying “Kill XX” or “Order □□ to poison △△,” and severe pain runs through my whole body when I try to suppress them.

It is fair to say that maggots are breeding inside my head.

That is the “Wicked Thought” that torments me.

The wicked thoughts are constantly trying to mold me into evil.

As if saying a villain must demonstrate their evil, they drive me toward evil deeds.

The nasty part about the wicked thoughts was that when fulfilled, a deep sense of accomplishment and fulfillment would visit.

Villains committing further evil—that cycle was established.

This must be the system by which Yoan became the “Incarnation of Evil.”

Therefore, I first needed to sever that cycle.

Worrying about the original story? That didn’t matter.

If I ended up killing someone like this, I would surely follow the same fate as Yoan. That is unacceptable.

That is why I simply continued to face these “Wicked Thoughts” earnestly.

Year 1. Unified King’s Birthday Festival – Yoan Absent

“Adaaaaaaaah! A’a’a’uuu!”

“I wonder what is wrong, Anje. Yoan seems to be suffering.”

“It is true… This Anje will go call a doctor!”

A few minutes later, the doctor arrived.

“Th-This is…! It seems Yoan-sama is receiving the ‘Revelation of the Hero’!”

The doctor said.

“Revelation of the Hero… What on earth is that…?”

“Since ancient times, it is said that those called ‘Heroes’ on this Welstern Continent received ‘Revelations.’ As if guided by fate, they accomplished great causes and made their names roar across the land.”

“But if that is so, why is Yoan suffering?”

“It seems Yoan-sama is resisting the ‘Revelation of the Hero’ with his own will. Since there is no distinction between good and evil in revelations, perhaps Yoan-sama is trying to follow his own conscience.”

“Eeeh, then what should we do?!”

“For this, there is nothing to do but for Yoan-sama himself to come to terms with it. All we can do is push him forward. Yoan-samaaa! Come now, follow the revelation! Liberate yourself!”

“A’daaaaaaaa…!”

Year 2. Autumn Leaf Viewing Party – Yoan Absent

“Gunuuuua’a’a’a! I don’t know… such a guy…! Anje… Is Anje there…?”

“Yes, it is Anje! What is the matter, Young Master Yoan?”

“Nua’a’a’a’a’a’a…! Anje… Who is Prince Robertttt!?”

“Eeeh… He is Young Master Yoan’s older Onii-sama. The same age.”

“Is that so, absolutely do not kill him…! Absolutely…!”

“T-That is obvious, is it not?! Besides, how many times have we had this exchange!”

◇◇◇◇

Year 5. Azerlan Empire 10th Anniversary Ceremony – Yoan Absent

“Guaaaaaaaah, M-Mother, you must not come near me…! My right hand is…! My right hand is moving on its own…!”

“It is fine, Yoan. Put it in my hole. You will feel better then, won’t you?”

“Guuuuuuu! Mother…! Could you please not say… ‘Put it in my hole’ so lightly… for a woman…!”

“Hah? What are you saying? Just shove it in, Yoan! Come on, hurry up and come inside me!”

“I-It’s impossible! I cannot possibly defile… Mother’s beautiful faceeeee!”

◇◇◇◇

Year 12. Engagement Meeting – Yoan Absent

“Go’o’o’o’o’o! Ha, hahaha! I know this, you shitty scenariooooo! You’re trying to make the dragon attack me when I carelessly get close like that, aren’t you! As a result, the dragon gets disposed of, and the heroine comes to hate me! Clever thinking! But such a thing cannot happen! As long as I stay shut in like this! Cough… Cough!”

“T-This is terrible. Young Master Yoan has become delirious…”

“Guaaaaa! A-Anje…? You came at a good time. Can you bring me water? I screamed too much and tore my throat… (Vomits blood)”

“Hyee. C-Certainlyyy!”

◇◇◇◇

And then—Year 16.

Swish, sunlight streamed in as I opened the curtains.

I instinctively squint at the outside light for the first time in a long while.

Eastern Welstern Continent, Azerlan Empire.

Imperial Capital Kingshaven.

The city where I was born.

The view looking down from this castle built on a high hill is, in a word, spectacular.

Beautiful. …That was all I could think.

“—It’s finally over.”

Fifteen years since the battle with the wicked thoughts.

I was convinced that I had finally overcome the wicked thoughts.

“Now, I am free…!”

There is no need to be a shut-in anymore.

Finally, I threw open the door of my room and sprang out into the castle hallway.

If this were a Di*ney movie, I would have started singing and dancing, but unfortunately, I possess no such talent.

However, let me just say my excitement level was about that high.

CRASH.

“Eh… No way…, Y-Yoan-sama?”

As soon as the maid saw my figure, she dropped the vase right in front of me.

The shattered vase lay scattered on the floor, and she was still looking at me, flustered.

I unconsciously licked my lips, and my feet naturally headed towards her.

“Hah… I am terribly sorry! I will clean it up right now…”

As soon as the maid recognized my figure, she began to panic.

Pitifully, the maid is shrinking away like a frog stared down by a snake.

I felt a switch flip inside my head.

It feels like I can hear the footsteps of the wicked thoughts.

Hmm, as expected, it came.

What flowed into my head was that usual wicked thought.

Normally, if I tried to suppress this wicked thought, I would have screamed “Gunuoooo!” or “Hogyaaaaaaa”.

However, now, look at this.

“…Crackle“

“Hii.”

A lightning-like “Blue Scar” flashed near my eyes.

The maid let out a small scream.

Fufu, the result is excellent; I am completely suppressing the “Wicked Thought.”

“Ah, I am sorry for surprising you.”

While wearing a smile, I trace that blue vein and make it disappear.

“Heh? U-Um…”

“Do not worry about it. You may break as many vases as you like.”

“Eh, th-that might be a bit problematic, but…”

Truly, the vase does not matter.

For me, the mere fact that I am walking outside like this now was enough.

I endured the wicked thoughts for these fifteen years to reach this moment.

“That doesn’t matter. More importantly, I am glad you are safe, Celta.”

“…”

——A smile.

Yoan is the incarnation of evil, but only his face was good.

It is safe to say his features are regular enough that a single smile makes a lady blush.

Not the evil smirk of the original Yoan, but smiling like a Buddha—that is possible for the current me.

“More than that, Yoan-sama, is it alright for you to be outside…? Kya!”

At that moment, Whoosh, a spring breeze pierced through the hallway.

Dancing petals, a fluttering skirt.

The wicked thought flowing in.

…Hah, foolish ghost of Yoan.

There are no blind spots left for me, who has overcome the wicked thoughts.

“…Twitch!”

I can see the edge of a garter belt, and I can see the plump thighs.

If I lower my head just a little more, I can see what lies beyond… see…

“…U-Um. Yoan-sama, what exactly are you doing?”

“…Eh, ah, white.”

The maid was directing suspicious eyes at me.

And rightly so, for I was pressing my cheek to the ground and looking up at the maid.

“…This is, well… breakdancing practice.”

“Buraykudansu… is it?”

The maid is looking at me suspiciously as I act strangely.

…Hmm, this requires a little more adjustment.

Well, all of this is Yoan’s fault.

I splendidly straighten my back and adjust my collar sharply, saying, “More importantly.”

“Right, could you call Claus to the training grounds?”

“Eh, Claus-sama…? What sort of business would it be?”

That is decided.

“—I want to have a match.”

A world of swords and magic, and this healthy body.

It is only natural to want to confirm how much I can move now.

“A-A match? But Yoan-sama, your body is…”

“No problem. Tell Claus—’Everything is resolved.'”

The maid looks at me in surprise and nods solemnly.

“…! C-Certainly.”

“Ah, I’m counting on you.”

Amidst the gently blowing spring breeze, I head dashingly to the training grounds.

‘Now then… I ended up spending fifteen years battling wicked thoughts, ignoring the original story.’

It was a herculean task to continue enduring for fifteen whole years without committing slaughter or assassination, but my past life’s experience proved useful there.

Because when it comes to “enduring,” there are probably few humans who can stand in the same ring as me.

I have no lingering regrets about my previous life.

My family was that, and I myself only suffered from illness.

Even if he is a villain, I think being able to reincarnate into Yoan’s body, which has no illness, is actually lucky.

Let’s rejoice that I was finally able to take the first step in this world.

The only problem is that the current me is Lv. 1 and a trash weakling with zero equipment.

At my age, one would usually be diving into dungeons and reaching around Lv. 30 to 40.

I have completely fallen behind. Which means…

Is there any insurance I can join even now—?
