Quirk Marriages (個性婚 Kosei Kon?, lit. "Individuality Marriage") are marriages that began to appear after Quirks manifested in society, sometime during the second and third generation of Quirk users.

These marriages were arranged with the sole purpose of choosing and/or enhancing a specific Quirk to be inherited down the bloodline, as a child will either inherit the father's Quirk, the mother's Quirk, or a new Quirk that's a combination of the two.[1]
