MTL - I Have a Store In the World of American Comics - ~ One thousand three hundred seventy-nine

This is the story of a crazy lich who possesses an internal game system and brings catastrophe to the entire world.

I want an S-Rank skill too! I want it so badly, I could die for it!

Eh !? WHAT IS THE POINT OF GETTING ONE IF I DIE !?

Two years ago, the mere fifteen-year-old scion of the Lin family, in front of the colossal behemoth that is the Murong clan, made a vow!Two years later, no one knows what he has gone through, but from the moment of his return, he radiates a brilliance that seems to compete with heaven and earth!(Note: The protagonist of this book is very aloof, cold, and passionate. Those who like to read about a military king's ambiguous romances and flirts, please bypass this one.)

Being given a chance and reincarnated is nice and all, yet why do I have to become that male friend who just watches the protagonist flirting with his harem?---World: Kaguya-sama: Love Is War - Hyouka ----
