Reincarnated Into a Game as the Hero's Friend: Running the Kingdom Behind the Scenes (Light Novel) – serie

A modern man is reincarnated into the world of a fantasy game he knows well: as Werner, the son of a powerful noble. The thing is, Werner isn't the hero or even the villain - he's a background character likely to die during a climactic siege! Werner seeks out and befriends the hero, but he doesn't have powerful enough skills to be a hero himself. Unwilling to die as a later plot point, Werner uses his knowledge of the game and his power as a noble to aid the hero and defend against evil attacks. That's when he realises that when he does so, he saves other people who were doomed as he was, which changes the 'plot' he thought was inevitable. As the hero's close comrade who can see the future, perhaps Werner will be a savior to this place, after all!

They may have separate missions, but Lord Werner - a Japanese office worker reincarnated into the world of a classic RPG - and his friend, the legendary hero Mazel, are both working to save the realm in their own ways. While Mazel walks the path of radiance, slaying the Demon Lord’s minions one by one, Werner uses his real-world knowledge to help manage the kingdom’s internal affairs. Managing refugees, fixing the water supply - it’s a lot of work for a supposed background character!

The Hero Mazel has finally set out on his grand adventure to defeat the Demon Lord, leaving his best friend Lord Werner—a Japanese office worker reincarnated into the world of a classic RPG—to hold down the fort. But just when Werner resigns himself to a mountain of paperwork, he’s called into a battle of his own! Can he rally his troops in time to save both the princess and Mazel’s family?

Someday, the hero Mazel will battle the Demon Lord with the fate of the realm at stake. But until that day... he better be carrying plenty of potions! While the hero is off saving the kingdom, it’s up to Lord Werner - a Japanese office worker reincarnated into the world of a classic RPG - to keep the rest of the world from becoming collateral damage. There’s no hero, luminary, or warrior of light who doesn’t need a friend like Werner! But can he truly defy the flames of fate and change the bittersweet ending of the game?
