Natsu Iwashimizu

Natsu Iwashimizu is a shy, awkward, and withdrawn 16-year-old who struggles to express herself after being put down at home and bullied at school. Her careful observation becomes crucial to her team's survival, as she records discoveries such as which foods are safe to eat. She develops conflicted feelings for Arashi while knowing that he already has a girlfriend, and Semimaru frequently teases her.
