Castlevania: Dawn of Sorrow (2005), the first installment of Castlevania on the Nintendo DS, is a direct sequel to GBA hit Castlevania: Aria of Sorrow ( https://tasvideos.org/1681M ). In it, Soma Cruz continues ( https://tasvideos.org/1759M ) to cultivate his unhealthy obsession with collecting the souls of his enemies.
Using the powers that only tool assistance can provide, every single possible soul is collected in a bit over 35 minutes. If you've ever played the game, you know what a pain those souls can be.
Very detailed information on the run is available in the author's comments ( https://tasvideos.org/3780S ).
There are also runs that complete the game as fast as possible with Soma ( https://tasvideos.org/2528M ), with Julius ( https://tasvideos.org/2459M ), and with Julius while staying in bounds ( https://tasvideos.org/2085M ).
