Major plot hole * spoiler*
Its running on netflix right now, it is so well written, but when we learn around episode 7 how a shinigami dies.....it make no sense at all
So this Shinigami Gelus dies because he saved a girl life by killing his soon to be murderer, so shinigami can take the life of a human but not extend it or else they die
But by killing random ppl with there death note they can accidentaly extend the life of another person ex: a shinigami can kill a guy one day, who happen to be an alcoolic who would have killed someone while drunk driving 2 days later!!!! So by that logic that shinigami should die. Its ridiculous there race would have been extinct a long time ago lol
