[₪] Ice Release is the advanced nature kekkei genkai of the Yuki clan, and allows the users to combine wind and water-based chakra to create ice which they can manipulate through willpower alone. Unlike other members of the Yuki clan, Saito's ice is dark black in color, taking the appearance of dark black diamond, rather than clear blue ice. He also has the ability to freeze over water molecules in the air in order to fuel his ice techniques, giving him a near infinite supply of ice to use.
Having heard rumors that he was able to unlock an "advanced" chakra nature, Saito trained his use of ninjutsu, rather than genjutsu or taijutsu. This resulted in him being able to make hand seals much faster than the average shinobi, as well as have increased control over his own chakra. In order to use his kekkei genkai, Hyōton, Saito must be able to mould two chakra natures together to create the final product of his kekkei genkai, ice, a difficult task for standard shinobi.
