Giselle saw the potential in Albus but wanted him to grow on his own.
His laziness disappointed her, but she never stopped believing in his talents.
She felt betrayed when he eventually left the company after his training period.

Albus respects Giselle, but he does think of her as a bitch. He'd never admit it though.
In the first mission she appears in by attacking Albus from afar, he gains the "Rage" state after realizing her identity.
