Gilga functions as a weapons artisan for the Hellhorde, crafting and maintaining their arsenal. Though primarily dedicated to her artisan role, she also operates as a torturer. Her specialty involves interrogating the sentient sword Excalibur by exploiting weapon-maintenance expertise—using precise sharpening and polishing to induce pleasure instead of pain, effectively breaking the sword's resistance. Her advanced technical skills in weapon maintenance and metalworking allow her to subdue Excalibur during sessions. Gilga collects magic swords passionately but treats them roughly, occasionally repurposing them as makeshift tools like gas stoves in culinary tortures. She shares a close friendship with the Hellhorde’s chief inquisitor, Torture Tortura. They use affectionate nicknames—"Tor-chan" and "Gilga-chan"—reflecting mutual trust, and their bond occasionally extends to collaborative interrogations. Gilga joins group activities with the Princess and other Hellhorde members, such as beach trips and hot spring visits, focusing on companionship.
