Devilman: The BirthEdit
Shortly after Ryo Asuka had explained to origins of the demon race to Akira Fudo, they prepare to return to the Makimura home. However before they could do so, the she demon Illuge uses her sonic screams to blast out the window's, then immediately after Texsch comes crashing through the ceiling. The two run, only to see the Gardalza coming the other way.
They get outside and get a distance before being attacked by Illuge and several other demons. Having to forcibly return to Ryo's home, they see Gardalza weaving a web in the hallway. They run past silently, but the demon notices and chases them. Akira and Ryo get into an elevator and start it up, though It proves troublesome to get going, descending just moments before she reaches them.
