Transmigrated to Game World with SSS Wife - Chapter 55: Upgraded Goblin Slayer

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 question I often ask myself, is the human desire for self-destruction never going away?

Travel through the endless apocalypse world, and find the answer behind every kind of demise!
