ジュン＝コーエン

She is one of only four Samurai Masters of the divine nation of Tesurai. Though a woman, her abilities are said to surpass even those of the great generals who command armies. While it's hard to imagine from her status and strength, she has a generally cheerful and friendly personality, and some commoners have even become friends with her without even realizing she is a Samurai Master.
