Marta Kompany

Norn's older sister. They run an apothecary together in the town of Ferio. After their parents' deaths during the demonic invasion, they only have each other. When Marta is kidnapped by Schtoll's minions, Norn tries to rescue her but is beaten back. Before she can be overcome, she is nearly run over by Cornelio's cart with Gil inside. His intervention eventually leads to her rescue. When Norn resolves to leave Ferio and travel together with Gil, she reluctantly accepts having also learnt the truth about her younger sister.

Spoiler

Marta has a boyfriend, but is willing to give her body to Gil for one night in gratitude for saving her from Schtoll and for taking care of Norn through the course of the story.

By the hot springs scene, Marta is willing to break up with her boyfriend and marry Gil together with her sister. It is not known to what extent she says this in jest, whether she's being serious or if Gil has been that successful in winning her over using his sex technique alone.
