Sumire Kageishi

Known to her students as the "Venomous Queen," this brilliant and stunning educator serves as Akiteru’s homeroom teacher. Beyond her intimidating classroom persona, she leads a secret double life as a struggling manga artist operating under the pseudonym Murasaki Shikibu-sensei. While she often battles chronic procrastination and missed deadlines, she remains a passionate lover of all varieties of sake, a preference reflected by her iconic sake bottle avatar.
