I'm Already a Wage Slave, and You're Telling Me Digimon Exist?

Suzuki Haruka transmigrated to a parallel world over twenty years ago. He has grown tired of its dazzling virtual cities, and the pressure of his job keeps mounting alongside technological progress. He thought he would spend his whole life as a corporate drone in this world, but one day, quite by chance, he passed through the gate to the Digital World and met a boy with a Leomon. With no partner, no Crest, and no Digivice, Suzuki Haruka can only start by making a Digivice by hand and taking care of logistics. In a world whose setting has nothing to do with the anime, he searches for the "Chosen Children" and whips these handful of troublesome brats into a team. Watching the children shine in the Digital World, all he can do is hide in the background, consumed by envy and jealousy. "Which godforsaken screenwriter said adults don't have infinite possibilities!" (Reader's note: The setting and plot are original, based on the Digimon setting, and have nothing to do with the anime's storyline. A few original Digimon will appear. The Chosen Children will take up a fair amount of the story and undergo noticeable character growth. The protagonist's logistics phase lasts a while and may feel a little slow, so please read at your discretion.)
