Weakness

Starla had immediate walked through the space to enter Ken's training hall, the moment his killing intent flared out of him,

As soon as she caught the glimpse of his figure, her senses locked onto him and she snapped her figures to change locations.

Arriving at a plains that had stretched far and wide, Starla and Ken faced each other.
