Shizuka is a calm, cool woman who often uses strategic tactics for survival. Such a case can be seen when she installed a camera on her bicycle to check for incoming dangers and used batteries to defeat a zombified shark. She is aloof and somewhat self-centered at first, as she tends to prioritize her survival instinct rather than cooperating with others, resulting in her questioning why people risk themselves to save others. Smart, resourceful and athletic as well as being very strong.
