Owari no Seraph/ Seraph of the end is one of my favorites! The characters are just soooo beautiful and I really love the plot! But my favorite part about the manga is the art style!! SO GODAMN PRETTY, For me Owari no Seraph is literally perfect in every way. I'm not a huge fan of Yuichiro (Yu), but thats why we have Mikaela (Mika) he's just sooo perfect.
