Sieglinde is a serious and contemplative Tokota who wants to succeed in everything that she does. Has high expectations of others, but even higher ones of herself. Always looking to not only prove herself, but also show others what she can do. Dreams of being an example to future generations of hunters.

While friendly with Edelgard, Sieglinde can't help but be a little bit annoyed by her stubborness. The fact that the other female is almost a head taller just adds to the rivalry, although Grimhilt is good at managing the both of them. Her closest platonic relationship is with Brume, with whom Sieglinde seems like a very different kind of Toko.
