Sigmund's puppeteer. He addresses Charlotte as Charl (シャル Sharu?). Sigmund cares about Charlotte and often persistently argues with her the things about her that he would like her to acknowledge and change for her own betterment that she would often fervently deny and often with a threat.
Sigmund advises Yaya on her afflictions.
Sigmund has a good impression of Raishin of finding him of being a sentimental person due to him treating him as a distinct individual and not as a literal automaton by directly addressing him therefore making him interested with him.
