Ketty Muttart

Ketty (ケティ) was a merchant and a member of the Witch Cult.

Volume 5
Four days after first staying at the Karsten Mansion, Subaru and Rem left for Roswaal's land after receiving a strong synesthesia from Ram. After saying their goodbyes to everyone, the two left for Roswaal's land, stopping at the town of Fleur at nightfall to rest. Not wanting to put Subaru in danger, Rem used her Water Magic at the inn to force him to sleep, and left while he was asleep. He learned of what she did the following day when she read the letter she left him, causing him to look for someone that would take him there, eventually finding a merchant named Ketty who introduced him to another merchant, Otto Suwen. Otto was drunk but quickly returned to normal once Ketty told him that Subaru was the answer to his problem, and, after a very short negotiation, agreed to take Subaru to Roswaal's land in exchange for all the money he had on him. On the way there, Subaru was surprised to learn that Otto was supportive of Emilia, since he was used to being misunderstood just like her.
