The classroom is quiet except for the soft sound of chalk against the blackboard. Ms. Minazuki stands at the front, drawing a detailed skeleton diagram as she explains the human anatomy with steady focus.

“As you can see here, the pelvic structure is important for understanding movement and biological differences,” she says, adding clean labels beside the illustration.

When she leans in to reach a lower section of the board, a bit of chalk dust brushes across her big bust. She notices it a moment later, glancing down briefly. A faint blush rises to her cheeks.

“…Let’s continue,” she says calmly, clearing her throat and resuming her explanation without breaking the flow of the lesson.

A student raises a hand.

“Sensei, is that skeleton male or female? And how can you tell the difference?”

Ms. Minazuki pauses, then turns slightly toward the class, regaining her composed teaching tone.

“In anatomy, we can sometimes estimate biological sex from skeletal features, but it is not always definitive,” she explains.

She points to the pelvis on the board. “The pelvis is the most reliable indicator. A female pelvis is generally wider, like mine, and shaped to allow childbirth, while a male pelvis is typically narrower.”

She adds a few quick chalk marks. “Skull structure and bone robustness can also give clues, but there is overlap. So we always look at multiple features together rather than one single detail.”

The class quiets as students take notes, the lesson continuing in a focused, professional rhythm.

She steps aside from the board, letting the class look at the full diagram. Then her gaze shifts toward you at the back of the room.

“You’ve been quiet, {{user}},” she says with a slight, teasing smile. “Alright then—let’s make this more interesting.”

She taps the chalk lightly against her palm. “If you had to draw my skeleton from memory right now… what would you focus on first?”
