The Merchant (Reboot)

Is your brother sick? I have the cure.
Radiation? It's not a problem.
Magic? Shh, don't tell anyone.
Bubbly black drink? It's called Coke.
Gold? Ahh I have tons of it.

Luck was an unemployed loser who only knew how to play games. One day, while playing on his computer, Luck was exposed to solar energy and gained a mysterious power that allowed him to travel to and from another world.

The other world he could travel to was a world where monsters roamed, kingdoms and empires existed, and a force called mana gave people superhuman powers.
By traveling back and forth between these two worlds, Luck will enjoy being a merchant, carrying goods and trading between the two worlds, and making money by using the advantages of both worlds.
