Enter one player mode, press Up to highlight Kuroko, and hold B until a confirmation sound is heard. The game will remain at the character selection screen. While continuing to hold B, slowly sweep the D-pad in a clockwise Full-Circle several times until Yuga appears in place of Kuroko. Note: The timing of the sweep is particularly sensitive. The same confirmation sound should be heard during the sweep. While continuing to hold B, press A to unlock Shura and Rasetsu.
