Rehashing 2000s ecchi plot for a manga made in years of our lord 2020s. Story I enjoy reading ecchi. It is stupid and silly. Seeing all the skullduggery reasoning to see calcium cannons to be exposed. Now keeping all that in mind, honk shoo mimimimimi. The stereotypical demon king who can only use erotic magic being reincarnated for centuries is kinda lame and is sadly overused at this point. But the best part is of the thin veiled story is the demon king and hero from 1000 years ago were actually in love. Wait you are telling me this has been used before? I also hate that mangkasbasic fetish bring forced down my throat. Oh you like big boobs? Get in line buddy, everyone else does.
Art
You will read this for the art alone. Ignore the texts on the page
This is where this manga is good or at least bearable.
The character design are kinda basic, but my god every single main fc has big boobs and that's all that matters!!!
Overall
6/10. It is being carried by the art alone. I think this would have been peak ecchi manga if it was made in the 2000s maybe 2010s. But sadly
