Your Majesty the Demon King, I'm Really a Loyal Subject!

The good news is that Danny transmigrated. The bad news is that he transmigrated into a cannon-fodder member of the Demon King's army who was slaughtered by the hero in the game. The even worse news was that the Demon King's army would completely collapse and raise the white flag before long... Recalling the demon race's various atrocities in the game, as well as his current predicament, Danny immediately made up his mind: I'm betraying them! I'm going to support the hero's party and strengthen myself by funding the enemy! While other demon officers were risking their lives on the front lines, Danny alone was reselling supplies in the rear! What? The hero's party is short on food? Sell it! Medicine? Sell it! Weapons? Sell them! Magic cannons? Sell them! The defensive maps of other allied forces? Sell them! And so Danny used the money he earned from supporting the enemy to rise steadily through the demon ranks, eventually becoming the foremost of the Four Heavenly Kings of the Demon Realm. Many years later, when the Demon Queen saw Marshal Danny, once her most trusted subordinate, open the city gates and lead the hero's party, fully equipped with elite Demon King's army gear, through the palace gates, she could not help but unleash a torrent of abuse! "Danny! You treacherous traitor who betrays your own side!" Danny protested aggrievedly: "Your Majesty the Demon King, I really am a loyal subject!"
