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".

After adorable “mermaid” Mamori is transferred to one of five artificial islands, she’s cornered, attacked and eventually saved by another beautiful transfer named Mirei. Unfortunately, even after the girl intervenes, Mamori’s attackers refuse to let up. Just when they think all hope is lost, Mirei and Mamori share a passionate kiss that turns the little “mermaid” into a powerful sword.<br>
