Tokiko is Mitsumi's second-year classmate and a dedicated student council member with her sights set on becoming the next president—she's been all-in since first year. She's the serious type, not one to let injustice slide, and Hanazono-sensei even pegged her as the most disciplined student in school. Mitsumi actually goes to her for advice on how to be more mature and put-together.
The girl is nothing if not hardworking. She runs her entire life on a detailed schedule that keeps all her council duties perfectly balanced, which Mitsumi finds genuinely impressive given how much she herself struggles with that kind of time management. But here's the thing: despite all that effort and discipline, Tokiko admits she gets recurring nightmares about missing her train. It's pretty telling that she's putting herself under constant pressure to succeed.
Her main weakness is how she comes across. She can be stern enough that people actively avoid her, and she's socially awkward to boot, so she gets misunderstood a lot. When she was honest with Segawa, who's going to captain the soccer team, it didn't land well—he was actually frustrated by how blunt she was being.
