Talk:Monster Girl Quest: Paradox/@comment-26146688-20150225212144/@comment-25707465-20150226091709

Considering that the three known ancestors have nothing in common, and all possess a different, sometime surprising gimmick about their look (Hiruko's clothing aren't exactly fitting in a fantasy world, we'll probably get to see Loli-Tamamo, and Minagi is weird for a succubus, even compared to the others done by the same artist), I wouldn't be surprised if the Plant and Insect ancestor are two creatures living in a symbiotic relationship and is considered one like the succubus Lilith and Lilim in the original game. Since in real life, a lot of plants need insect to survive, procreate and vice versa, that'd make sense.

Also, Promestein didn't say the seaweed she revived was one of the 6 ancestors, she said it came from the era of the first monster lord. It's possible it comes from one of the organism The Darg God Alipheese lived with, like the flower in Alice XVI's head.
