I Was Reincarnated as the Strongest and Most Evil Noble Who Controls the Darkness of the Kingdom

The inept eldest son, Alvert, was born into the marquis family, descendants of the ‘Night King’.

He possessed a twisted personality and gained immense power, subjecting various heroines to his revenge. He indulged in his desires to the fullest… only to meet a tragic end.

After his death, I seem to have reincarnated as that ‘protagonist’. At this rate, I’ll meet a terrible fate at the end of my pleasures.

If that’s the case, I’ll abandon all the happiness that comes with being the protagonist and enjoy a peaceful life as a mob character.

…That’s what I thought, but…

“You really are the reincarnation of the Night King!”

“Preparations for the first night are ready, Nii-sama ♥”

“I might be falling in love with you!”

…Why did it turn out like this?
