This ending is for the Arranged mode, the remade version of Akumajou Dracula X68000. The Regular mode ending is kept in its regular form and can be found here.
After the defeat of Dracula, the camera begins to circle the castle. As we zoom in, the towers on the end of the clock tower begin to collapse, signaling the submerging of Castlevania.
The bridge leading into the upper portion of the castle collapses as the destruction continues. When we zoom back out, the foundation of the castle is totally destroyed, and the stone embodiment finally gives way. Dracula is dead, and Castlevania will be dead with him.
From afar, I assume from the view of Simon, the sky becomes alive as the sun rises from behind the mountains. We fade out as the sun becomes its brightest. The credits roll as still shots of Simon battling bosses flashes in the background.
