Siren's "Wakatta" | Explaining Its Meaning and the Scene Where It Appears
Siren's reply in the movie's Island Arc became a talking point: did it mean the culprit was identified, or that Siren agreed to stop the attacks? We trace why the two meanings overlap, using the surrounding dialogue confirmed in the original manga posts.
Why Siren's Reply Can Be Heard Two Ways
Siren's short reply is known in the movie's Island Arc as a single line with two possible meanings. One is that Siren has figured out who ate the Mermaid. The other is that Siren accepted the islanders' plea to stop attacking them. Siren acts with finding the culprit as its goal from the start, while the islanders prioritize ending the attacks above all. Even with the same reply, the question each speaker and listener believes is being answered differs.
However, the original manga post images we examined do not actually depict the single word used in this article's title. Because guessing the kanji, punctuation, and doubled consonants from a transcription of the film's audio would not satisfy the condition of quoting only wording verified in the images, we do not treat it as a quotation in this article. Below, we present the surrounding dialogue actually readable in the original images in scene order, tracing how Siren's understanding changes.
The First Meeting: Introducing Themselves
"We are the Siren and the Mermaid"
Seated around a campfire, Siren introduces itself and the companion above to Chiikawa and the others. Just before this, it also mentions having attacked them by mistake, and here it is calm, treating them as partners it can converse with. When Chiikawa and the others mention remembering hearing about the Mermaid, Siren shifts the topic to what happened on the island. At this point, its understanding is a straightforward exchange: answering questions and explaining its own situation.
Speaking of Loss: One of Three Companions Is Gone
"There were really... 3 of us mermaids"
Siren explains that there were originally three mermaids who sang together and picked bugs off each other's bodies. It is a confession of losing companions it shared daily songs and care with. It then reveals that a mermaid was eaten, and the story's focus shifts to why its companion was lost. What Siren wants to know at this point is one thing: who did what. The foundation for reading the later reply as identification of the culprit lies in this loss.
At the Village: Continuing the Attacks Until the Culprit Comes Forward
"I'll keep eating them until someone comes forward"
When Rakko asks whether it is searching for the culprit, Siren answers while holding islanders in its grip. This is a scene where searching and attacking have become a single method in Siren's mind. Because islanders who are not the culprit are also caught up in it, what those around it need is to stop the harm before uncovering the truth. For Siren, however, the logic is that continuing the attacks will force the perpetrator to come forward. Even looking at the same incident, the conditions for considering it resolved are already misaligned at this point.
Encounter with the Search Party: Jumping to the Conclusion That They Brought the Culprit
"Could it be... you brought them to me!! The culprit!!"
Seeing Chiikawa, Hachiware, Usagi, and Furuhonya together with an islander, Siren takes this to mean they have brought the culprit to it. It rejoices before the group can deny it, and even makes a move as if to release the captured islander. It is a reaction that fits the situation in front of it to its own goal, forming the conclusion first. The later short reply could be a sign that Siren has found something connected to the culprit. That range of possibility is unsettling.
The Curry Scene: Suspecting a Different Intent
"You mixed something weird in, didn't you!"
To weaken Siren's song, its companions add a trick to a curry and approach. While enjoying the song and the dancing, Siren suspects that something unusual is mixed into the dish offered. This scene shows its sharpness in not taking others' actions at face value and constructing its own reasons. However, its guess being correct and understanding the other party's words in the same sense are separate matters. Precisely because it notices things quickly, the room to read the single word as a declaration of finding the culprit grows stronger.
Just Before the Subjugation: Hachiware Questions Whether It Is Right
"This really... is the right thing, right?"
Amid the fierce battle, Hachiware asks the islanders whether defeating Siren is truly right. Siren is a dangerous opponent, but the group also knows it has acted out of grief for the lost Mermaid. Here, the judgment of ending things with force itself is called into question. The demand to stop the attacks and revealing the culprit Siren wants to identify are things that should ideally be discussed separately. Because an attempt was made to end both at once, the reply's meaning also cannot settle on one.
Hachiware's Plea: Asking Siren to Stop the Attacks
"Please! Stop attacking everyone!!!"
After Siren's thrashing tail sends islanders flying and it covers its mouth in apparent surprise, Hachiware delivers this plea. The answer the listener seeks is clear: a promise not to attack anymore. So it is natural to take the short reply immediately after as consent to stop the attacks. Meanwhile, Siren's goal remains finding the culprit to the very end. If it noticed a different clue at the moment the plea was heard, then Siren alone was answering a different question.
At the Shore: Checking What It Hit
"Did I hit something?"
At sea, Siren and the Mermaid swim near islanders in a boat. Sensing that something it threw may have hit someone, Siren stops and looks back. It does not ignore a small sense of unease but tries to confirm the cause. Even in its search for the culprit, Siren connects events around it to clues. The short reply also sounds like a line from the moment it sensed something because this quickness to check is consistently depicted.
The Final Scene: Silence Leaves the Truth Hidden
"Shh..."
The two islanders each put a finger to their lips, urging silence as if sharing a secret. Afterward, Siren brings one of the islanders to its mouth, and everyone around gasps. There is no scene where Siren explains in words what or how much it understood. Because of this silence, the end of the attacks the islanders hoped for and Siren's grasp of the culprit remain overlapping to the very end. This mutual misunderstanding, connecting to both, is what makes the single word so frightening.
Conclusion: Different Questions Overlap in the Same Reply
Siren consistently seeks to know who took its Mermaid companion. The islanders and Chiikawa's group try to stop the attacks that sweep up even the uninvolved. If you hear the reply right after the islanders' plea, it sounds like consent; if it is the moment Siren reached the culprit from the situation, it becomes a declaration of discovery. Two questions standing side by side, both awaiting an answer, is what creates the split in meaning.
Rereading the original manga posts, Siren is not a being incapable of conversation. It introduces itself, explains its loss, jumps to conclusions seeing an islander as the culprit, and suspects a trick in the food. The problem is that it reads others' actions through its own goals and presses forward with its enormous power. With that accumulation in mind, the reason the short reply leaves both reassurance and unease at the same time becomes clear.
Frequently asked questions
What does Siren's reply mean?
To the islanders it sounds like consent to stop the attacks; from Siren's side it sounds like the culprit who ate the Mermaid has been identified. Because the question each party believes is being answered differs, the single word works in two ways.
Does that single word appear in the original manga post images?
It does not appear in the original manga post images we examined. For that reason, this article does not guess its wording from the film's audio and quotes only the surrounding dialogue readable in the original images.
Why does the reading that the culprit was identified hold up?
Siren consistently searched for the culprit after losing its companion and judges situations by connecting them to its own goals. The final silence also never explains what it understood.
