Lord Of All Existence

Living a life of being a black company office worker, Leonard decided to commit suicide only to find himself wake up in his apartment.

Finding the situation rather strange, he chose to take a stroll outside, only to find that corpses litter the ground with devastation everywhere and at that moment, "Ding,ding,ding!", a sound came out of nowhere and announced.

"Congratualations to all newcomers to your new world, Elgaia! This will commemorate the tenth interstellar battlefield! To all newcomers as a newcomer bonus, we have decided to give all newcomers a [Skill Coupon] and a [Grand Draw Coupon]! We hope you all enjoy the bloodbath!" "To all newcomers, this world is similar to that of Planetary Star Grade A 1781-Earth. If, you wish to see your status, just think of seeing it. It will also be set to automated mode soon so for those who can't, don't worry, we'll do anything for our entertainment. The item bag works the same in which you will it to appear for you to see."

Finding this all amazing, Leonard felt amazed and decided to will his item bag to appear and used the coupons.

"You used a [Skill Coupon]" "You managed to draw the Passive and Active Skill [Concealed Existence Lv. MAX]".

"You used a [Grand Draw Coupon]" "You managed to draw the Passive and Active Skill [Heaven's Luck]".

Looking at his skills, Leonard decided to see if he could escape this hellscape and become the Lord Of All Existence.
