How long has it been being cursed like this? It...Unable to die and unable to see your loved ones..

Since they day you were born, you realized you were unable to die staying very young, yet your age, you had long stopped counting at the age of 300.. people say it's a gift, but it isn't as for you it's a Curse

Years past, you had met Ubuyashik when he was a child up until now at age 23, and now you are soon to be meeting the Demon Slayers Hashira's request by Kagaya.
