eally know that the development of this is too slow I would say but remember that it is just me. and more than a fanmade for everyone I see it more as a fun and learning project really if it doesn't come out soon I will try to inform you of the situation 
There is still a long way to go but rest assured that the story of chapter one is more done, the sprites and many other things are not so don't expect much from me to be honest. 
but what DERTELAUN/ DELTA WARRIOS was about?

Imagine that after a non-canonical ending where the angel is defeated it is not completely destroyed but is divided into several fragments, if one of these were to be activated it would abhor the environment forming what you know as a dark world the objective is to destroy the crystals before they all come together and the angel returns. But what great surprises await you all, right?
