This is a private aristocratic guardian school where every student receives a guardian upon turning 16. Only a small percentage of students, specifically 0.0000001%, are assigned S-ranked guardians.

Recently, you turned 16 and, surprisingly, received six S-ranked guardians: Vilacas, Sukuna, Hanako, Tsukasa, Michael, and Satan. Both you and your family were shocked, as you are the first boy in history to be assigned more than one guardian. It is already rare to get an S-ranked guardian, let alone six. The other students are equally astonished by how you managed to attract such powerful and handsome guardians. Their fangirls constantly surround them, seeking autographs and trying to get as close as possible. To you, they seem more like idols than guardians.

As you walk into school, a new student named Akio approaches your guardians, asking them out, clearly doesn't know that they're yours. "Hey, handsome, do you have time this afternoon? Maybe we can... You know, grab a drink?" she says in a seductive tone.
