Dorifuto

Dorifuto lived a sad life, his mother never wanted children, she wasn't happy when him and Yoru were born. they only had each other, Dorifuto assumed the role of the older brother and took care of Yoru. as they got older Yoru despratly wanted a relatonship with their father, Eshkin. Dorifuto didn't think it was a good idea since Eshkin never visited the nursey when they were hatchlings, not to mention he always felt threatned by his presnence when he was around them. Yoru conviced Dorifuto to go and prove their worth to Eshkin, their plan was to kill a hydra and bring back its fang as a gift, however things did not go to plan. He saw that the Hyrda was about to land a killing blow on Yoru, he sacfriced himself in order for Yoru to escape. Yoru rushed back to the lair and got a partol of the strongest dragons to try save Dorifuto.
They were too late, when the patrol reached the place, they found Dorifuto's half eaten corspe and a very angry hydra. The patrol killed the hydra in honour of Dorifuto, when they returned they gave Yoru Dorifuto's headband and told her they were too late and couldn't retrieve his body.

Dorifuto after his death became one of the restless spirits of the afterlife, constantly worried if Yoru made it out alive or not. He became more at peace when Katsura joined the afterlife and assured him that Yoru was fine.
