Juuou Mujin no Fafnir is terrible. There’s no avoiding that and no value in digging deeper than that. It has one of those narrated openings that tells us that monsters showed up for now reason and without warning and that people started to gain abilities like monsters…
…and then dumps us on an island with a teenage boy who’s drawn like he’s twelve stumbling on a girl who looks about the same who’s naked on a beach for no reason. His sister is there, though not naked, and she’s the student council president at the all-girls school that he’s enrolled in 120 seconds later. JMnF is a cliche, pure and simple.
If you liked World Breaker last season, and if this show’s dialog eventually manages irony, without sounding forced, then maybe you would like it. The art is sub par. The effects are sub par. The animation is sub par. The voice actors are doing all the can but the writing is a smelly turd.
If you can get through all of that, or if you are massively desperate for loli no-nipple boobs, loli-harem, then maybe. Maybe you would watch this.
But realistically you wouldn’t watch this. Even in a slow season, there are shows you’ve missed in previous seasons you can go back and watch or games to play or for God sakes go read a book.
Don’t watch this show!
