Forum:What's the final boss of the first Devil Summoner?

Hi there! I can't find any information about final boss of Devil Summoner. I'm making a small SMT comepedium on my PC...

There's a video (warning, spoilers!)

Looks like Lilith was put together with Tiamat and Yamatanoorochi tpgether in blender.

Thanks for answers!
