Know any good Youkai(demon) anime? Mostly with tragedy in them? Coz I really like such anime and I want to watch some more.....

Well the only I can think of is Inuyasha.

Claymore, YuYu Hakusho, D.Gray-man...all good ones

Well, I thought of Nura: Rise of the Yokai Clan.

Kanon but demons are not the main issue and it's bound to make you get tears in your eyes

or i can recommend vampire knight but as the name already says it's not about demons but Bampira and i pag-ibig the hero's tragedy poor guy Yuki is a asong babae if you haven't already seen it then you should

ooh and for less tragedy and madami demons try inyasha,or bleach works too

hope i helped

inuyasha

rosario vampire

you can try kuroshitsuji...

try shounen onmyouji

I found it epic and life-changing. The ending also made me cry. Pretty sure you'll pag-ibig it unless you've already watched it ..... but oh well
