What’s a hydra devil? :0!! Also, what does their department do research on?

And it’s the medical and general scientific department! So all sorts of science stuff, even though she’s personally very biased towards the medical end of the research!

Well all demons and devils in this lore have to assimilate the soul of another being in order to stabilize themselves, however, they end up taking on traits from whatever they assimilated, Indra decided to go for a type of Hydra, so that’s what that means!
