Eternal Life Begins with Taking a Wife - Chapter 8

For three years, Finn Taylor is utterly humiliated. He has endured everything from physical beatings to verbal abuse.

But this life as he knows it is about to be turned upside-down as he reclaims his position as the head of Peregrine Hall.

Your two pairs of purple pupils seem to be somewhat different, and you may wake up with Tensei Eyes or Samsara Eyes.

When will you open your eyes?

Look at luck!

- Description from novelbuddy

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.

A protagonist reborn in another world.
