Shirase is a hacker who solves every problem by being exactly the wrong person in exactly the right moment, and the show knows this is funny every single time. The short format means each episode lands its comedy before it can overstay the joke, and his complete inability to take anything seriously becomes the actual plot device. What keeps you watching isn't the King of America or the hacking setups, it's waiting to see which compromising position he'll talk his way out of next, usually while making it worse.
Shirase is a brilliant programmer operating on his own terms. Rather than chasing paychecks, he accepts jobs for a kind of payment that only someone like him would value. His manner hardly fits the assignments people hire him for. When the evil King of America starts stirring up trouble over the internet, Shirase finds himself kept constantly busy. Each new adventure draws even more odd and interesting people into his life. The result is a short-format comedy with science fiction and ecchi elements, built around a freelance hacker with remarkable skills.
