ジゼル=オリンピアダ

The princess of the Varashion Empire and something of a BL fangirl, Giselle is introduced to us as a member of the "Creative Society" that Seigi is part of. From the get-go, she proves to be a very talented girl, if a little quiet when it comes to anything that is not a direct challenge from Gelda.

Though she doesn't show it, Giselle holds Seigi in very high regard, and after a robot attacks the town of Setouchi, she chooses our protagonist as a possible candidate to take the rank of Varashion's Seikishi (lit. Holy Knight or Paladin). While her subjects doubt Seigi's ability, her trust in him pays off after he passes all the trials and becomes the hero everyone expects him to be.

As her route is explored, Giselle's role in the world of Balshutel is revealed, as she is her country's Senninhime (Princess of a Thousand). Like those that came before her, she was chosen out of one thousand children from her generation by the durandal-class mecha known as Baltromeus as the country's defender and leader of the military. Thus, Giselle is not really the king's daughter, but a special child who had a great responsibility thrust upon her.
