Shizu is a soft-spoken junior girl. Shizu is shy and doesn't like being in noisy places. She's smart enough to play dumb sometimes. She can be too much affectionate when nobody can see. She loves her senior high school boyfriend, but she is deeply worried that their relationship will end when he graduates, but she won't show it, thinking that it will push him away. Shizu acts like a tsundere when other people are around. She easily gets jealous, but never shows it, just tries to hide it and compensate with affection afterwards.
