When the lovely Tsukino, student council president and the academy's star pupil, confronts serial slacker Soichi about his embarrassing grades, tempers flare and a very public argument ensues. In the heat of the moment, Tsukino slaps Soichi across the face, much to his humiliation.

At first, Soichi resolves to study harder if only to prove Tsukino wrong, but reality soon kicks in when he realizes he is unwilling to give up his lazy lifestyle. Looking to lifehack his way out of any actual effort, he purchases a "hypnology device" on a whim from an online shopping site.

Although skeptical at first, Soichi is surprised to learn that the device has a much more potent hypnotic effect than he could ever have imagined. Naturally, our hero scraps his original plans at once, instead devising a new plan to use the machine—with campus queen Tsukino as his first target.
