The Male Lead Monster Lives Under My Bed

Entering a 19-rated romance fantasy novel?
Yeah, it was fine until then.

But out of all the characters, the one I possessed
happens to be the villain's daughter, and she is about to die!

While I was pondering how to escape this unlikely fate,
I got a present from my psychopath(?) war-maniac(?) Older brother…

Squi..shy?

Oh… isn't this a slime?

This slime that had only been plump and squishy started to speak?

"Myumyu! (Friend!)"

With the appearance of this new monster friend,
my fate as Irina Sordier…
is going in a different direction?
