Reincarnated in a depressing erotic world but living a normal life (right?)

Honestly, I wasn't expecting the princess's reaction upon waking from her curse. I mean, in these kinds of situations, one usually receives a 'Thank you.'

Or on the other hand, some confusion about what's happening...

"Aaahh.... Finally... Finally!!! AAAARRGGHHH!!!"

But I never expected that the first thing she did was to go crazy while tangling her hair and crying uncontrollably. However, at this rate, it could be dangerous for herself and consequently for the end of the story, so first we have to calm her down.

And I have the perfect "techniques" to do it.

"Everything is alright now, calm down {"Art of Relaxing Massage + Art of Healing Massage"} at maximum power."

"Aaahh... Aahh.... Ah~"

[the silver knight uses a combo move on the princess]

[it's super effective!!]

Yep... Now it seems she's calming down, so it's time to ask to find out how to end the plot of this story.

"Princess, allow me to introduce myself. My name is the "Silver Knight," and would you allow me to know your name?"

PERFECT!!

Practice paid off. I look and speak like a mysterious knight... Sniff... This is beautiful... Sniff... Thank you, world, for this opportunity!!

-------------------------------------------------------------

"My name is the "Silver Knight," and would you allow me to know your name?"

Faced with the presentation of the mysterious silver knight who had freed her from her nightmare, the princess, for the first time in a long time, had the opportunity to say her name to someone else.

"You don't need to be so formal after saving me, and I apologize for the delay in my introduction. My name is Lethe, princess of the kingdom of Zarzamora."

"It's a pleasure to meet you, Lethe."

"Yes, likewise."

For the first time since falling into that "cursed sleep," Princess Lethe was having a normal conversation, able to move and speak. However, the more time passed, the more she noticed the strangeness within herself, since just moments ago she should have been feeling a tide of uncontrolled emotions on the verge of madness.

But now she found herself calm and even felt relaxed, feelings she hadn't experienced in a long time.

"I want to ask you something, are you the one causing this calm within me?"

"You are right. If I hadn't used my massage, it seemed you might hurt yourself."

"Thank you so much!! From the bottom of my heart!! THANK YOU!!"

Faced with such strong and sincere gratitude, the knight seemed stunned for a brief moment before reacting.

"You're welcome, it was my pleasure to help."

After this exchange, the princess had a long conversation with the knight, who prepared all kinds of food for her and entertained her with all sorts of stories, although sometimes he seemed to talk to himself and casually played with the straw dolls around him.

For a moment, Princess Lethe believed she had returned to the time when her parents were still alive, the citizens strolled, and the children played around.

Giving some "peace" to her heart, however...

"It seems time is up."

"Huh...? What's happening?"

Before her, the straw dolls and the silver knight began to glow as they slowly disappeared one by one.

"Princess, no. Lethe, it's time for me to go."

"Why?! If you're planning to disappear, take me with you!!"

"I really wish I could, but it's not possible since "this" world needs you."

"The... "world" needs me...?"

"That's right, that's why I can't take you with me."

"Then... A-again... I'll be alone..."

Just as Princess Lethe collapsed, feeling how the only pillar that freed her and made her feel "alive" was beginning to fade away, she felt a cold touch on her head, comforting her slowly and gently with great tenderness.

"You are not alone, Lethe. Even if I leave, it doesn't mean we won't see each other again."

"Huh?"

"I'm just going home, and from there I will always support you."

"Uuggh... Sniff... It's a promise!! Right?!"

"Yes, it's a promise."

And with those words, he disappeared before her eyes.

And since the departure of the "Silver Knight," Lethe lost all motivation to move, spending her days motionless in the place where he had disappeared.

Curiously, her body seemed not to age, nor did it need water, food, or any other basic human necessity.

Lethe thought this might be because of the time she spent cursed, but she had no interest in investigating further or doing anything more.

She only limited herself to getting lost in her memories while giving up on the real world before her to live in the memories she spent with the "Silver Knight." That was all she could think about, however...

"Princess, I'm glad you're alright!"

An annoying voice pulled her from her sweet fantasy, returning her to the monotonous and gray world in which she lived.

"Who are you?"

"I am the prince of the kingdom of Cardantia! And I have come to rescue you to consummate our engagement!"

Although there is supposedly someone in front of her, Lethe is unable to perceive or notice what he looks like, and although he was speaking, she couldn't remember what he was saying either. Currently, in Lethe's mind, there were only thoughts about the "Silver Knight" while she ignored or dismissed everything else.

"I don't care, get out of here."

And so, with a lethargic voice devoid of all emotion, she uttered these words, showing a lost look on her face.

"H-how dare you disrespect me! I am offering you the happiness of marrying me!"

"I don't care."

"You, don't you see that there is no greater honor in the "world" than this!!"

"In.... the.... "world"..."

At that moment, something inside Lethe finally clicked at those words...

"That's right!! Now you understand the opportunity I am giving you!!"

"Aaahh... Now I understand... All of this.... It's the world's fault..."

"Huh...?"

And with those words as a trigger, the "curse" reactivated, generating an overwhelming amount of thorny vines from Lethe's body as she slowly rose.

(Whip!!)

"Aagh!!"

Immediately, the vines struck the prince as they began to wrap around him, draining his strength.

"W-what do you think you're doing?! If anything happens to me, you will be hunted by the entire world!!"

The prince, in an attempt to survive, tried to use his position to make her see reason and escape, but the response he received was simple and plain.

"I... don't... care...."

"H-hiiiii!!!"

It was there that the prince finally could see Lethe's gaze, only to discover empty eyes without any light returning his stare.

"It's because of this world that I can't see him...."

The vines grew and spread more and more, becoming larger and stronger each time, while at the same time all vegetation withered and every building collapsed.

"I have nothing here... I don't care about anything else....so..."

With each word she spoke, it seemed as if the vines went more insane, destroying everything in their path, while Lethe rose on a large vine at her feet.

"If it's to find him....then...I don't care about destroying everything!!"

The last thing the prince saw in her eyes was the somber figure of a woman looking with hatred at existence itself before being completely covered by an endless number of vines.

From the day she awoke, the original princess had already died asleep in her long lethargy, having detached herself from everything she once valued. In her place, a monster was born, focused on a feeling of love and dependence towards the one who brought her out of the darkness.

And thanks to the great spiritual energy that Mireya gave her before leaving, combined with the remnants of the original curse, a new curse was born, one that weakened all organic and inorganic matter at an accelerated rate until it disappeared while spreading wildly and uncontrollably.

But thanks to the lack of opposition from Lethe, she was able to "assimilate" the curse into her body, turning it into a kind of cursed ability known as...

"The Sleeping Embrace of Thorns."

She was no longer Princess Lethe; in her place arose the demon lord who represents Sloth, Lethe.
