The King of Fighters Ash Saga/Shion

Shion is a video game character in The King of Fighters series and the sub-boss of the The King of Fighters XI game.

History
Shion works under Magaki and moves for the resurrection of the seal-moved Orochi. She uses a form of barehand wushu, a spear, and a rope dart for his moves. She is very eager to accept challenges.

Shion is first shown in the mid-game cinematics after the mid boss fight, showing her talking with Magaki, who warns Shion of betraying him. Next, Shion is seen taking a break after turning the finals arena into ruins. After she is beaten, Shion gets surprised by Magaki who whisks her away to a different dimension. The most likely case is that since she is definitely upset by this, Shion doesn't waste time at all when she finds an opening on Magaki's defense when he's trying to flee via dimensional rift. Shion kills Magaki by driving her spear right through his heart, killing him quickly, even though she is then trapped in the other dimension.
