Street Fighter 5: Arcade Edition is getting a new character in the form of Kage, a dark force tied to the sinister aspects of Ryu’s soul.
Announced by Capcom, Kage is Ryu’s Satsui no Hado (“surge of murderous intent”) and only desires to survive, destroy and conquer. For reference, Akuma gave into his Satsui no Hado, though Ryu is constantly struggling to keep his at bay. If Ryu had kept his Satsui within him, he would have turned into Evil Ryu. However, this one became sentient and became Kage (“shadow”) and lives to prove that Ryu is nothing without him. To do so, it seeks to challenge Akuma and Sagat, two of Ryu’s greatest rivals.
