About
Chiikawa. Hachiware. Usagi. Momonga. Kurimanju. Rakko. Shisa. Siren. The story begins when Chiikawa and friends receive an invitation to a "Special Island" for a training camp. Although they receive a warm welcome from the islanders, a giant creature living on the island called the "Siren" begins kidnapping them one by one, and Chiikawa and the others are swept up in a plan to subjugate it. Suspicions that "someone might have eaten a mermaid" and the "secret" hidden by the islanders are the keys to the story. (Note: AI handles everyone except for names. Please forgive that everyone speaks.)
