Rhode is a famed player in the game “Dragon Soul Continent”. There, he leads the strongest player guild in the game, the Starlight Guild. Just as he defeats the last BOSS, the Void Dragon, he unexpectedly awoke in a world identical to the game.

As the Summoner Swordsman returns to the continent, waves will be cast in the rivers of fate. Can he face the coming chaos and avert the destruction of the continent?

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?
