Overpowered, Overstayed, Over It

A Hero was summoned from Earth, given amazing powers, and sent to kill the Devil-Demon-Daemon King. He succeeded! But now he won't leave, and he keeps causing problems for the people of the world of Zinn. You are the new Hero summoned. Your task: Kill the previous Hero. And unlike the last loser given power, you were trained in Earth's modern military combat techniques and tactics. And the God of Death and Destruction was given free reign to equip you with appropriate gear and talents. Time to frag a Hero who's overstayed his welcome!
