Ketty Muttart

Later on, it is revealed that he is one of the fingers of Petelgeuse Romanee-Conti. Subaru uses this knowledge to spread disinformation among the merchants, knowing that Ketty would fall for it and report incorrect info to the members of the cult. After he had fallen for Subaru's trick, he was arrested, the magic formula that allowed him to become a finger and explode in a dangerous situation was removed by Ferris, and he was taken in for questioning about Witch Cult activity, never to be seen again. The last mention of him was when Otto said that he was disappointed with Ketty after discovering he was a member of the Witch Cult.
