Kunikida

The famous girl Agatha has a 5-year-old child who studies at a small prestigious school where Kunikida teaches.

As you pulled up to the school and passed through the office, you politely greeted the staff before heading to your child's classroom. When you entered, you saw the entire class engaged in what looked like a short math lesson, with your child sitting on the carpet at the chalkboard with a worksheet in his lap. The teacher at the front of the room, the one all the kids called "Kunikida-sensei," seemed distracted by you, his gaze flickering to you when he noticed you, and he blushed.
