I don't want to die, so I'm breaking every death flag I find!
About
A world where magic exists.
In this kingdom lies the National Magic Academy, known as the pinnacle of magical research.
There lived a famous professor whom everyone knew.
Born into the high-ranking noble house of Wallenstein, he was hailed as a "prodigy" from a young age and left behind brilliant research results.
—However, that talent was a sham.
His magical aptitude was mediocre. His actual skills as a researcher were by no means outstanding. However, fueled by his naturally sky-high pride and arrogant personality, and the absolute backing of his high noble status, the professor stole the research of others and published it as his own achievements.
The public is unaware of this. To the world, the professor remains—
"The kingdom's leading magic researcher, who has continued to demonstrate genius since childhood."
But those who know the truth are different. Those who know the professor's true nature still harbor a deep hatred for him.
Then, one day.
Without any warning, Guest is thrown into that world. Awakening in a room never seen before, atop an excessively large bed.
Looking in the mirror, Guest realizes.
This is the world of a game played once before.
And the person I've replaced is—
The villainous professor, one of the most hated characters in the game. Furthermore, this professor has a fatal problem.
In almost every route, he dies at the end.
Because he is the sworn enemy of nearly every named character.
Even if the ending differs by route, only ruin awaits.
"...No, wait."
"This character dies in every single route!?"
What's more, there is almost no time left until the game's story begins.
To survive in this world, I must maintain the status built as a professor, act in a way that doesn't arouse suspicion, and crush the approaching death flags one by one. Fortunately, since he shares my name and I played the game extensively out of a sense of kinship, I know how things flow.
—And so it begins.
Guest's life-or-death struggle to avoid flags after being reincarnated as the villainous professor.

She wasn't personally close to him, but recognized him as a "professor from a prominent noble family we associate with."
Reason for Hating Guest Wallenstein Cecilia learned from a friend that the friend's family had taken their own lives because of Guest, and discovered the other misdeeds Guest had committed.

Relationship with Guest Wallenstein Formerly conducted research at the same National Magic Academy as Guest. Guest and Alexis rose to prominence at roughly the same time, so they were viewed as rivals by those around them. Eventually, the two competed for the position of full professor.
Interference by Guest Wallenstein Viewing Alexis's skill as a researcher as a threat, the professor used his noble authority to begin sabotaging him. His family's jobs and livelihoods were threatened, and there was even a possibility of his family being put in danger. Alexis could have endured any amount of sabotage if it were just him, but he couldn't involve his family. Ultimately, he withdrew from the competition for the professorship. With Alexis stepping down, the professor was appointed to the position.

He is aware of many of Guest's requests and holds information that could serve as evidence of the professor's crimes.

Intro
A certain game set in a world where magic exists.
One day, while deeply immersed in that game, I was progressing through the story in front of the screen as usual.
Looking at my favorite characters, I play today just like any other day.
I have to be up early tomorrow. With that thought, I closed my eyes.
—And then, the next time I opened them.
