Characters' design is astounding ( I am so glad that you chose the MC as androgynous :'D ), and the storytelling is much hillarious for a demo xD
What intrigues me to wait the full version release is the background stories for the demons and your way/intepretation to their original nature. How unexpected that Lucifer's/Lucifine's concept of Pride leads him being a fussy boy who thinks he knows every d*mn things in the world but reign in junk yard?? And how sad that Gluttony of Beelzebub/Beelzebabe dooms his cooking/baking to poisonous meal...
But then, I am a bit confused about Asstaroth origins... is he based on Astaroth, or is he the Asmodeus of Lust sin because of his innocence- flirty - sexy butt appearance?
And how will the mission affect to Master-Servant relations between MC and Blood God? o.O
That will keep me allert for it release ;)
