Madara-san (斑さん) is the president of the Chemistry Club. She is a second year student with black hair and glasses. Madara is very shy, and appears to disapprove of inappropriate behavior. When she overhears Sempai shouting at Assistant after a sword trick fails ("Pull it out!"), she is shocked and mistakenly thinks something else is happening. Madara allows Assistant to join her club, but asks him to stop doing "shameless" things. Madara is very knowledgeable in science, and likes to perform experiments that show how physics and chemistry work. She also thinks magic is fraud designed to trick people into believing in the supernatural.
