yup it is a subgenre called furry/beastiality
there are more of this genre on mrm (or myreadingmanga) which is a dedicated site for yaoi manga
The same can be said of all the yaoi, hentai, ecchi, smut, gore, and horror manga on this site. It's why the warning is there. It's not the site's responsibility to police what people read, nor is it yours.
Yeah I'm kinda new in this manga thing so I'm surprised that they kinda normalized Beastiality.. otherwise thank you for your explanation!
Although they're often grouped together, this isn't the same thing as bestiality.
^^^^^ This, right here. I wish everyone would stop using that word to descibe this. Furry, animal characteristics = correct. Bestiality = something else entirely. If there wasn't anything human about the Beasts, then yes, it would be that. But they're half-human.
^ yea what they said
^ yeaaaaaah
Is this kind of thing normal in manga? Even though its only an alternate universe? Because everyone can read this including children.
