can some1 explain why tragedy is one the genre before i read this manga.Dont spoil just say like main character die or something happen.Im not really a fan of main character dieing at the end or sad endings. 2jku

Brother has incurable disease. They have no parents, older brother has to work for every penny.

Actually, the main character is killed in chapter one...then he is turned into an immortal (hence the name).

I thought that it was a pretty good story. Also, if you had not noticed, this story has a sequel called Cavalier of the Abyss.
