No, Owari no Seraph is not a yaoi. While the series does have strong male relationships and some subtext, it is primarily a dark fantasy and action anime with a focus on the struggle between humans and vampires. The main character, Yuichiro Hyakuya, has close relationships with both male and female characters, but the series does not center around romantic relationships between male characters. **
