The Aura Soul Spark Due (原因オーラソウルスパーク Gen'in Oora Souru Supāku) is one of Rose's special attacks, exclusive to the OMEGA Mode of Ultra Street Fighter IV. This is a variation of her Super Combo, Aura Soul Spark.
Executed by performing two quarter-circle forward motions and pressing punch, Rose performs her Aura Soul Spark technique. Each version of the attack has a different name, and is a distinct version of its Super Combo in Street Fighter Alpha 3.
The overall execution of the move is determined by the punch button pressed: light punch version (named Level One) has Rose make a regular Aura Soul Spark, as in Street Fighter IV; medium punch version (named Level Two) makes a series of attacks before finalizing the opponent with a multiple-hitting Soul Spark; and heavy punch version (named Level Three) uses the medium punch version of Soul Reflect which deals two hits before finalizing the opponent with a multiple-hitting Soul Spark.
