Rogue Hero

Keith Herbert was a studious youth in his second year of college. He was an avid gamer, and quite dexterous with his fingers. He was highly skilled, and would have had a great life ahead of him in the tech field, building ever smaller and more powerful computers, if not for having been ripped from his life and tossed into a fantasy world named Azaron, along with 3 others whom he neither knew nor liked the looks of.

Assigned by the Spirit Orb the powers of the 'illustrious' Rogue Hero, he was quickly taken away by one of the sages and trained. In Azaron, the Spirit Orb allows one to see their own statistics, obtain skills, and level them. Two years later, he had obtained the Relic Blade, found a Dwarven Grandmaster smith to repair it, and then made his way to the Demon King, where he issued a challenge of honor.

Having won the duel, the other 3 heroes arrive, and using the spell 'Banishment' on Keith and the Demon Princess Kalypsa, send them away from Azaron, never to return.

In another reality, the highly advanced Devilium are being attacked by creatures from space, creatures they have no idea how to deal with. Their leader having just died of old age with no heir, they cast a summoning spell, hoping, praying, for a miracle, to give them a new ruler and a chance at survival. The Summoning is a success, and Kalypsa is summoned... along with Keith.

Due to Banishment, Keith has lost all his stat points from training, returning to his before summoned strength, but in this new reality, the first things he noticed after the pain of being summoned wore off was that the Devilium live in a world where their Ranks and Levels appear above their heads, and their armor and weapons remind him of Storm Troopers.
