Dawn of Sorrow is the first DS Castlevania game, and it's also the sequel to the GBA Castlevania game, Aria of Sorrow. Everyone is trying to kill our hero Soma cruz, since in the last game he absorbed all of Dracula's attributes. You can always trust weird cults to try and bring about the end of the world by unleashing this power.
This short movie is a glitchy, warped run that beats the game in a mere 8 minutes and 20 seconds. This is achieved by zipping around the castle and collecting souls while out of bounds that you normally couldn't get.
