Ice Sword: Yukianesa

Mucro Algesco: Yukianesa has the shape of a katana. Continuum Shift states its blade is ice, and its power is manipulating the water in the atmosphere. According to Noel in Calamity Trigger, the ice Yukianesa creates erodes life, which explains why Jin seems to freeze everything for a short amount of time during his Astral Heat. "Yukianesa", "snow woman", is a Japanese fairy (more famously known as a "Yukionna"). "Mucro" means the sharp tip of a sword, and "Algesco" means "to become cold".
