Mamori Tokonome

Оригінальне ім’я: 処女まもり

A high schooler forcibly sent to Mermaid Island after contracting the A-Virus. Mamori is a gentle girl who abhors violence. This puts her at odds with her ability to transform into a deadly weapon as an Extar. She is frequently teased over her family name being written with the same Kanji as "Virgin".
