I've been meaning to release this for a while now, but took me quite some time to find a good balance of: not having the main female character being a zombie too, having detailed zombies while still keeping an anime style in anime models instead of realistic, and having a horror look without going overboard. It can also produce NSFW outputs.

Trigger word: zombie. You should also use it together with multiple boys and/or crowd.

Other tags to modulate the effect: ugly man, glowing eyes, blood, guro, horror or horror (theme), black eyes, rotting, undead, etc.

I recommend weight 1.0, but you can increase or decrease depending on desired effect, and CFG 5-8 should be good for most models.
