Kana

An ex-con who was freed from prison by Yoshioka. Due to having her memories erased, she does not remember the reason for her imprisonment. Under direct orders from the Caspar Faction, she enrolls in the magical girl school as a student. Due to information about her situation leaking, her classmates are wary of her due to her past conviction. Kana's magic allows her to to have any question truthfully answered by whoever she asks. However, if the question's recipient doesn't know the answer, is misinformed about the answer, or they don't understand the question, Kana's magic may produce unfavorable results.
