Hildegard Silbe is a head engineer for Void Garden and the creator of Garden's AI Silber.
Hildegard has a shy personality, often shuddering and awkwardly laughing when she has to talk to someone else. Kuroe notes that she is a sensitive person and will often cower or burst into tears at the slightest hint of antagonism or questioning.
Nevertheless, Hildegard has a sharp analytic mind when it comes to technology, being the one trusted by Kuroe to verify the legitimacy of Ruri's video. At times, when hiding behind a monitor, Hildegard can be somewhat trollish, often enjoy pranks that involve giraffes.
Unlike the other Knights, Hildegard was chosen not for her combat skills, but rather for her technical prowess as an engineer. Hildegard is a genius hacker, being able to tamper with Hollow's Ark's security systems while she herself is still at Garden. This included preventing Mushiki's group from being eavesdropped, disabling security cameras, and even sending a 3D hologram of a giraffe to disturb the Azurs.
