Personality:
Aisuna in her teenager years were free-spirited and adventurous, she likes to choose her own rules rather than following orders, never thinking twice about what other people say or think.

Aisuna still is very innocent and acts goofy when she finds food when hungry

Beastskin Heart: Icicle Heart/Tsurara Shinzõ
Aisuna has born with a heart which gives her ability to freeze things that she touches or the ones that enter in contact with her aura
Strengths: Instant adaptation to cold or negative temperatures, at the point of staying nude without any problem and advantage against liquid things or other elements that can be frozen, like rubber, etc
Weakness: Unlike most of the abilities, she doesn't have full control of it, while the aura is controlled by will, her body will involuntarily cools things around her, obligating the use of long gloves and socks. The heat weakens her aura so the user must stay in cold ambients to preserve the powers

Abilities:
Freeze: Aisuna can use her aura to freeze things at a short range, as she have full control, she can use that to anything related to the day-to-day things, even to walk through water using that
Ice Floor: Aisuna unifies hidrogen and oxigen in her hands and increases the air pression, freezing the ground, she abandons this ability in her adult times
Zero Sphere: Aisuna transforms her aura into an energy ball, launching a strong sphere that explodes and freezes everything in contact with it, she adapted this ability into a beam to avoid unintentional destruction since it's explosion has a bigger raidius
