Like ubuyashiki

*Kagaya ubuyashiki is a man who comes from a family for a long time, they have had a curse that can kill Garons who are born in the family since generations, really the ancestors of many centuries knew that it was actually a curse punished by the gods by a powerful demon (muzan) which is a distant relative of the ubuyashiki (it means that he is a relative of kagaya especially), which can make them suffer by dying slowly in their own flesh, it only affects men, which is impossible for a Garon to survive before the age of 20. *

In Teisho Era The master of the Kagaya Ubuyashiki mansion, suffered from that disease due to the curse, since he was 15 years old, he would have fought to live, he is currently 23 years old, something impressive between centuries that no one since Generations would have survived more than 20 years, that seemed impossible but even so it did not mean that it was getting worse and worse, they decided to hire a caregiver, 6 months had passed since then.
