Moreover, his subordinates in the main story were used by the last boss, and then abandoned and killed with the same fate. ......?

"Damn it!　I won't die!"

Kaim decides to work hard to avoid being killed.

It had been a year since I possessed this body, and I finally discovered the identity of the original character.
But… I was revealed to be Evelyn, a handmaid who would help the runaway of the future imperial princess, Caesar.
My only way to survive was to control Prince Caesar's rampage and raise him to the throne.... more>>

"I have to find Your Highness's guide. Contacting a guide will allow you to awaken your abilities without going into a rampage."

In an attempt to survive a little longer, I set out to find his guide... only to discover that I was the one and only guide?
Moreover,

"I have no reason to dislike Your Majesty."
"Then that's good, isn't it?"
"...Huhh?"
"If you don't dislike it, then it's good."

As I was gradually preparing to leave the palace, the newly crowned Emperor looked at me with sparkling eyes.
He held both of my hands tightly, as if he had no intention of letting go.

I had only awakened him, so why was he following me around like a drenched puppy?
And why wasn't the rampage stopping?

***

"It's about time for me to vomit blood, isn't it?"
"Why would you say I'm going to vomit blood in front of me? Why?"

Unbeknownst to him, I was eavesdropping when Caesar gazed lazily and whispered.

"I need to go on a rampage... so that Evelyn won't leave me."

At that moment, the door I had been waiting for opened, and our eyes met.
His sky-blue irises were stained with bewilderment. <<less

“Sure,” she replied. She’ll just do C, then! No biggie.

“If I tell you to go east, you can’t ignore me and go west,” the Prince added.

“Yes,” she nodded. If she can’t go west, north or south works fine too.

In the Psychic Combat class, her classmates’ psychic manifestations were all ferocious beasts like tigers, leopards, eagles, and wolves, extremely fierce and intimidating enough to make three children cry at a glance.

Adelaide had risked her life in exchange for playing the role of the Duchess, but she never had any intention of loving Klaus.

He was a Northern noble with an elegant facade, yet lacking in any true nobility. Dealing with such a Duke was always a source of embarrassment for Adelaide, who had lived her whole life as a noble lady.

They were merely using each other. So there was no way that this could be love, just something as insignificant as that.

“You mean something to me.”

The more she fell for him, the deeper she fell, everything became a mess. Like an uncontrollable fire.

“Do you have any value other than yourself?”

Klaus sharply rebuked her with his lips against her throat.

“I want everything from you, even your very breath. How is this not love?”

“You’re completely insane…”

In the worst possible way, you made me realize. The fact that all we have left between us is nothing but hatred. <<less

Diana Pursler La Monte Heimüller.

A princess from the Duchy of Batemann, who appears to be on the run, staying in a convent on the Brecht estate after two marriages and bereavement. She was curious about the Archduke’s eyes.

A woman with misfortune, doesn’t she seem like a good fit for me, who is called a monster? The Archduke’s suggestion flashed into Diana’s mind along with the scandals that followed him.

Leopold Kaiser van Brecht.

Archduke Brecht, the owner of the prosperous West, the Grand Duchy of Lichtal. An undefeated commander who is brave enough to be known by everyone’s name. However, he is a man with a vicious character who weak people fear just by making eye contact. And a man with two or three g**itals. They said that there were plenty of women who entered this man’s bedroom and ended up dying or going mad.

In summary, Archduke Brecht is a pe*vert in bed. But for Diana, returning to the Duchy of Bateman was more tragic. She proudly told the Archduke that he would give him a fertile castle if he divorced after giving birth to an heir. <<less
