Hiro Sakaki, a high school student, died and was reborn. Allen McCarthy went through a similar experience. Yumi Hitomachi and Rina Shirasaki, meanwhile, were subjected to Summoned Magic by the Gods. The four of them have come together to experience the life of the next world and to investigate the otherworld. Will the four of them be able to lift the veil of mystery? Furthermore, the enemy he faced was not just the people around him. Even more powerful than ordinary humans.
Since Lady Goddess granted me a second life, I will conquer this new world and transform it into a utopia! Author’s note: This is a story of kingdom building and conquest. A reincarnated person uses his knowledge to develop weapons and develop his nation in a world similar to Earth, albeit with a fantasy twist. The fantasy element is relatively weak in combat but is prevalent in production, taming, and mechanics. So there won’t be one-man armies, or sword saints and heroes.
One day, Theodore found a game application that installed itself on his cellphone. A game called Isekai Guide. In the game, it is stated that the main character is a woman who transmigrated from earth to another world named Etheria. Thodore's task in the game is to guide the main character, Rosalina, to kill the Demon King. So that Rosalina can return to her original world. But... Theodore didn't know, that the characters in the game might not be just game characters or npc. And Rosalina, might really be a victim of his world trapped in Etheria. If Theodore knew this, what would he do?
