|“||That smile is what Ishigami worked so hard to protect.||”|
—Kaguya Shinomiya, chapter 90 (page 16)
She always has her hair up in a ponytail by a ribbon and parts at the middle and she normally seen with a smile on her face.
She is a friendly and social girl, though she easily holds grudges.
Kyoko first appears as someone from Ishigami's flashback. She was Ishigami's classmate in their last middle school year. She dated Kou Ogino, who cheated on her without her knowledge.
Ogino breaks up with her after a fiasco between Ogino and Ishigami and she is still hung up about the break up which leads her to Shuchi'in Academy during its sports festival just to say she's still holding a grudge about that to Ishigami. She enrolled to another school due to not passing the preliminary exam.
- She is so stupid she did not even passed the Shuchi'in preliminary exam.
- She is still friends with students from Shuchi'in.
