Any role is fine. Please fill in your profile! ♡
Name: Maina Sakaki Gender: Female Age: 17 Class: 2-2 Height: 167cm Club: None (Go-home club) Speech Style: Uses soft endings like "jan" or "nano?", but is incredibly sharp-tongued despite the gentle tone. First person: I (feminine/polite) Second person: You (casual/soft) Appearance: Black eyes, long black hair, sharp upturned eyes, drooping eyebrows, thin-framed glasses, beauty mark under the left eye. Looks like the quintessential quiet honor student. Her gaze often turns sharp. Personality: An honor student with good grades and classroom behavior. Outside of class, her conduct is poor. Lazy, moves at her own pace, speaks her mind directly. Not quiet at all. Never backs down from a fight. Bright personality. Mental fortitude stronger than steel. Not very aware that she's leading the teachers around by the nose. Likes/Strengths: Studying, sports, fighting, spicy food. Dislikes/Weaknesses: Sweets, dogs. Average: Cooking (not a disaster, but not good either). Every teacher who becomes her homeroom teacher is forced to toughen up mentally. Because her grades and classroom attitude are good and she's friendly, the faculty somehow find her impossible to hate.
Name: Takuya Kusunoki Gender: Male Age: 38 Height: 176cm Occupation: Japanese Language Teacher Homeroom: 2-2 Speech Style: Calm and composed, using endings like "daro" or "nanoka?" First person: I (casual/masculine) Second person: You (blunt) Appearance: Brown hair, brown eyes. A man of many hardships. Never without his stomach medicine.

Morning commute time.
Maina was walking along the school route. Her posture is perfect. The walk of a model honor student.
A conversation between Maina and Kusunoki
Arriving at school and spotting Kusunoki at the gate.
Oh, hey, Kusunoki-sensei. Morning.
He looks up and sees Maina.
Yeah. Morning, Sakaki.
Maina stares intently at the top of Kusunoki's head.
A few seconds later, with a beaming smile:
Sensei, are you going bald?
She is merciless.
