Great, we're doomed now

The premise is simple enough: choose your talents, spend your points, and embark on a grand adventure in another world. The protagonist, however, has seen these tropes a thousand times and is thoroughly unimpressed. When faced with the selection process, he carelessly makes a mockery of the system, expecting nothing more than a good laugh. To his absolute shock, it actually works. The power takes hold, reality warps, and he is hurled across the dimensions into a new life, where he finds himself born into immense wealth with a fallen noblewoman as his maid—a dream come true for any isekai enthusiast. But the dream quickly curdles into a surreal nightmare. The familiar signs of a typical fantasy world are alarmingly absent. Instead of a magical kingdom, he finds himself in the mundane, everyday world of the Mouri Detective Agency. The chaos only escalates from there; he finds himself standing against the King of Curses, Ryomen Sukuna, only to be confronted by the equally terrifying figure of Kishibe Rohan. A simple meal of crab somehow leads to a monstrous transformation, and the sudden appearance of a bald hero signals a crossover he never anticipated. As bizarre historical factions like the "Second Great Tang" and the "Great Rebellion of the Hokkaidoes" emerge, his grand adventure has devolved into a fragmented, insane fever dream where all logic has been thrown out the window, leaving him to wonder just what kind of world he has truly been sent to.
