I believe viewing this on a large device will fix the problem
Or just enlarge the image in general

All of the images does look like that if you view it on a fit view mode

I mean you are fitting 4kx6k res on a mobile phone after all
Ofc it will look sharp asf

pc master race for reading manga

 

[Gatenka]

Skinny ass looking Demon King.
Oh wait, his wife is a Succubus, that explains it.

Also, wanna bet that Flay's father was the one that gave the demon lord those scars, and it's also why he's coughing so much. The fight must've been really brutal.
