Story guide

A Mermaid emerges from the water and finds the small boat carrying Chiikawa, Hachiware, and Usagi. Two small companions float beside the Mermaid, who sings that the island's food is delicious and filling. Hachiware and the others hear the song, take it as being about food, and begin singing happily themselves. The Mermaid and the group in the boat remain on the same water surface while looking at one another, ending the scene with a song about food echoing through the cave.

Story guide

A Siren rises large from the water in front of the boat that had been joining the Mermaid's song. The Siren's eyes turn red, while their Mermaid companions float nearby. Chiikawa, Hachiware, and Usagi are startled and use their oars to move the small boat away, but the Siren parts the water and gives chase. Waves lift the boat high, and in the end the three and the boat are thrown into the air. The singing scene abruptly becomes a direct pursuit and the danger of capsizing.

Story guide

By the campfire, Chiikawa, Hachiware, and Usagi warm themselves with the Mermaids. Siren says that one of their fellow Mermaids is missing, explaining that this has left them unable to sing as a group of three or remove the bugs that cling to their bodies. When Hachiware says they remember hearing that people eat Mermaids, Siren takes this to mean that someone on the island may have eaten one. The Mermaids also say that someone came out from the village, and Chiikawa and the others begin considering clues to the culprit. Their exchange about checking the warmth of the fire becomes a brief respite before questioning begins.

Story guide

Siren appears in the settlement and approaches where Chiikawa, Hachiware, Usagi, and Rakko are. The Mermaids are riding on Siren's head, and a small islander-like figure can be seen at their mouth. Hachiware remembers a Mermaid companion pleading for this to stop and understands the danger of the situation. Siren appears to have an islander in their mouth, and those around them begin to flee. With the suspicion surrounding the Mermaids appearing as an attack in front of them, the settlement immediately needs to evacuate. Those running away have no room left to ask about Siren's purpose.
