I’m a Supporting Role in a Horror Game, Don’t Kill Me

Suddenly thrust into her favorite mystery murder game, our protagonist embodies Arviche Green, a supporting character doomed to bite the dust. Compounding the chaos, she wakes up in the house of the prime suspect, Duke Leikas Learmond, as the in-house tutor to his niece and nephew! Convinced of the Duke's guilt, she juggles evading the main storyline while also uncovering the truth. With her virtual lives dwindling, can Arviche game her way out, or is a game-over fate sealed?

I possessed the person who will be the tenth victim, the tutor Arvice Green.
The prime suspect is the Lakers, the Duke of Leermond, the employer!
“…Sah, the killer.”
“Miss Green, you’re sure I’m the culprit.
Yes?”
He lost his life in the last conversation he had with the Lakers. His remaining lives are two hearts.
‘If you run out of hearts, you really don’t know what will happen then.
So, get out of the main flow of this game as much as possible.’
Arbice’s actions to distance himself from the Lakers, the prime suspect, contrary to my intention, I have to attract his interest…
“Remember when I said the sheep I drew were interesting?
That statement should be withdrawn.”
It was a pleasant sound to hear. The murderer’s interest is just awful.
“It might not be enough to say that it is interesting.”
[The favorability of Lakers Rearmond has increased.]
‘….uh? Isn’t this?’
