Ore no Ie ga Maryoku Spot datta Ken – Sundeiru dake de Sekai Saikyou

To utilize the seemingly endless supply of magic in a nearby power spot, the Prussian princess Dianeia attempts to extract its energies alongside her order of mages. However, to the group’s confusion, this procedure inadvertently summons a house from another world that happens to be linked to the same power spot. Due to the house’s connection to the power spot, Daichi, its sole inhabitant, has been absorbing magical power since his childhood. As a result, he is remarkably stronger than any other being in this new place he has been transported to. Unaware of his own abilities, Daichi carelessly manifests them, making a lasting impression on Dianeia and her companions. Despite wishing for a life of leisure, Daichi realizes that his presence in this realm will only attract similarly mighty entities toward him. Consequently, the balance of power will be inevitably disrupted—not only in Prussia but in the rest of the world as well. [Written by MAL Rewrite]
