One day, red threads appeared on the fingers of all humans worldwide. Since those bound by that thread were destined for lasting relationships, it became known as the "red thread of fate," and a new era dawned where thread-based romance became the norm. While all this was happening, a red thread suddenly appeared on the finger of the protagonist, Tsumugi, who, incidentally, just happens to despise "thread-based love"....

Touma Funasaka is offered an unusual recommendation for his next school by his homeroom teacher. The school in question is Toyashihara Academy—a national, full-boarding institution that accepts only students through recommendation, with no general admissions. It also happens to be his teacher’s alma mater.

The low tuition and full-boarding system seemed like the perfect opportunity, so Touma decides to enroll. But what awaited him was an academy that defied common sense—a place built atop a vast underground dungeon, ruled by sex and violence.

Though bewildered at first, Touma quickly adapts to the decadent academy life. While indulging in a corrupt and hedonistic youth, he also joins comrades to form a party and challenge the dungeon’s depths!
