Hourin was the kirin of the kingdom of Hou during the reign of Chuutatsu, the father of Shoukei; Chuutatsu is the second king she had chosen. When the king becomes increasingly fanatic about enacting harsh laws in hopes of ensuring his people become righteous, Hourin beseeched him to be more lenient. Her efforts unfortunately pushed further towards his belief that he needed even more austere measures and when Hourin has contracted shitsudou, Chuutatsu fails to see he has lost the way and continues to ruthlessly punish his people.
