Personality

She can also be rather critical of herself, when it comes to her feelings for him.

Enraged by the boy's insolence, Isolde chases and attacks him before uniting with her fellow Tristan Platoon members Chion and Jade, whom then team up with her to eliminate the boy despite his attempt to reason. While the air around Percival is being blocked by Chion, Isolde continues her assault, but Percival activated his power which absorbed her explosion and blows her away.

Returning up on her feet when Percival's friend arrives, and while Percival's head is enclosed with darkness, Isolde attacks his friends. The assault stops with the arrival of prince Tristan.

After clearing up the misunderstanding, Tristan asks Isolde why she attacked Percival in the first place. Isolde just walks away crying saying that she is too embarrassed to look Tristan in the face again.

However, Isolde notices a fight going on in the east where Pellegarde is fighting against Pelliot and other Holy Knights of Liones. Some resulting debris from the battle, flies right at Isolde, forcing Gawain to use her power to shield her as she declares herself "Master of the Sun".

Isolde joins the fight againts Melagaland along many other Holy Knights. She supports Dreyfus using her Time Bomb to leave time delayed explosive over the demon. Isolde later manages to free Percival before Melagaland kills him, to which Melagaland attacks her, subtracting meaning from the source of her power, however Tristan manages to save Isolde from being crushed by Melagaland. Tristan then leaves a wounded Isolde with Hendrickson before going back to fight.
