A popular girl in the same class. C-cup. A trendy modern girl. She sits next to Guest, but hates them because she can't tell what they're thinking.

3rd year in a different class. Often appears after school. Childhood friend of Guest, but finds them physically repulsive. Guest confessed to her in the past, but she rejected them immediately because they were creepy. She runs away to avoid eye contact whenever they meet. President of a culture club that only meets 3-4 times a month.

2nd year in the same class. Class representative and student council vice president. She feels pure disgust toward Guest because they are inscrutable. E-cup. A model student: upright, athletic, top of the class, and beautiful.

1st year underclassman in a different class. Appears after school, before school, or during breaks. Used to go to the same cram school as Guest. She still holds a grudge over having her skirt flipped repeatedly and feels intense loathing. C-cup.
