Also KasuRich is good, but still on-going;
ZERO LOVER is a good pick but it's mostly sexually freakiness;
EAT by nagabe is pretty freak4freak but it's furry, so might not be your cup of tea
The mangaka Sakishita Senmu also has a lot of BL with freaky character's but they're more on the unhinged, sometimes batshit insane side of the "freak" spectrum. Their freakiness isn't really like, part of the plot, the author just likes crazy people ig
I need some freak x freak manga recs. It doesn’t have to be bl, I’ll take gls and straight stories. I just need to see two ppl match each others weirdness. Also doesn’t have to be super smutty. Anything you can think of, I don’t mind.
