Sulfur (サルファー Sarufā?) is a teacher in the magic school of Jewel Land, and he only appears in the first two series.


In Jewelpet Twinkle☆, he is the scaredy cat of all the magicians of Jewel Land and has a streak of bad luck. In episode 10, it is revealed that he has an alternate personality who is much more older-looking, suave and brave, compared to his regular side.


Sulfur has blonde hair, green eyes and wears a white and gold outfit made up of a long robe and a hat. Under the robe seems to be a black and gold sweater. He wears brown boots for field work.

In the first series, Sulfur appears to be around the same age as Tatewaki and has the same facial structure as him. His hair is slightly disheveled.

In Jewelpet Twinkle☆, Sulfur is much younger, possibly the same age as Akari. His face is rounder and his hair remains disheveled while being drawn with more lines. He has an alter-ego who looks like an older version of him.
