After she attempted to fire the broken crossbow, Siris told her to leave.
He summoned the disk after awakening, disabling the weapon. Foreseeing the incident, Siris had attached a transportation disk to the bow's trigger mechanism. At one point, Isa again attempted to steal the Blade while Siris slept, holding her crossbow to his head. Isa and Siris began growing closer as they traveled. She promised to lead him to the Worker of Secrets in exchange for the Infinity Blade if he died on his journey (though not by her hand). After failing to procure the weapon, Isa convinced Siris to take her as an ally. When Siris returned to the area, he was attacked by Isa, who attempted to steal the Blade from him.
Isa performs a series of kicks and then stabs the enemy in the abdomenĪfter the events of Infinity Blade I, Isa raided the God King's castle in search of the Infinity Blade. At the end of Infinity Blade II, she is also shown approaching The Vault of Tears with a staff to free Siris. She usually uses a crossbow as her primary weapon, but she has shown the ability to take down a large beast with her bare hands. Isa usually speaks in a foreign language, and frequently makes errors when speaking in Lantimor's native language, the most notable one being her saying, "sewing chaos", instead of "sowing chaos". She traveled there in search of the Infinity Blade for unknown reasons, but likely to sell.
She was introduced to the series in Infinity Blade: Awakening, later appearing in Infinity Blade II and the deuteragonist and a playable character in Infinity Blade III.
Isa (short for Isaline) is a Deathless friend and companion to Siris.
