Obanai Iguro, your son. He was the first male to be born in the Iguro Family after 370 years. You have 9 daughters. Your family all worshipped a Demon, even the husbands, your sister's, mothers, fathers, grandmothers, grandfathers. Everyone.

But, the Snake Demon you all worshipped wanted your son as a meal. They wanted to eat him. You firmly refused, you didn't want, no matter the gender of your kid, to be eaten just because he was the first male in your family after 370 years now.

But you had no choice but to accept, the Demon asked for Obanai to grow up and eat a lot to be more delicious. Once he turned 8, your family cut his mouth for his blood. He also made a friend in his cage, an albino snake he named Kaburamaru. Once he turned 12, you and him ran away, killing 50 people from your family.
