Kia is indeed in tune with the darkness, and is one of her two main abilities, mainly in the form of magic-based attacks. Being a mid range fighter, Kia wields a hefty, rather large, curved blade akin to that of a guillotine. Despite its size, she wields it one hand with ease like a knife and utilizes swift swings and keeps it mid-range. Alternatively, she may charge her weapon with darkness and increase her attack potential. Overall, her fighting style resembles that of Sora's Limit Form: chaining normal attacks into various special attacks. Her other ability is shapeshifting, which serves to be as formidable as her darkness powers. Kia is compromised completely out of a metamorphic liquid that can assume many shapes. When she discards her weapon, she will start using this ability as four large, arm-like appendages appear from anywhere on her body. Entangling her opponents in a multitude of tendrils of ambushing her opponents from behind, Kia is at her most unpredictable when using this power. It is also because of the ability that she can withstand many physical attacks. Despite these strengths, Kia is not weak against the light, but ice. Another downside is that while she can gain experience and grow stronger, she can't learn any extra abilities. She has no White Magic to defend herself with, so she must use on-hand items.
