A page collecting the personalities of all twelve Chiikawa characters. Chiikawa wears the skin of something small and cute, and is a story about labour, friendship and anxiety. Chiikawa, sitting the certification exam in tears; Hachiware, brightening the world with a cry of it will work out somehow; Usagi, freedom itself — read those three as an attachment trio of anxious, secure and avoidant, and it becomes clear why that world is so gentle and so sad. The film released on 24 July 2026, Chiikawa: The Secret of Mermaid Island, is based on the island arc (the Siren arc), a long story serialised over roughly eight months. Siren, who moves vines with a song; Hitoha, who crossed a line to save a friend; Jiro Shima, who changed the course of a battle with a very hot curry — the film's main cast are read through attachment style too.
This page reads 14 Chiikawa characters through three layers: MBTI as the outward personality, attachment style as the hidden side, and a Big Five type. Rather than simply assigning a type, Why this type from what they do in the story and where they came from — that is how this site works.
📊 Attachment styles across the Chiikawa cast
The comparison baseline is the attachment split across 42,256 quiz responses: 30.1% secure, 15.5% anxious, 13.7% avoidant, 40.6% fearful-avoidant.
Chiikawa (anxious) is held by Hachiware (secure) and protected, without a word about it, by Usagi (avoidant). That ideal coexistence of three attachment styles is what the comfort of this work actually is. Momonga's demands for recognition are a clear textbook of the anxious type. On the island-arc side of the film, meanwhile, Siren and Hitoha are both fearful-avoidant: out of the same motive, not wanting to lose what matters, one turned to revenge on the island and the other to capturing a mermaid. Nobody settles which of them was in the wrong, because the two motives have the same shape.
🧩 Reading the relationships in Chiikawa through attachment
Under a very cute drawing style, Chiikawa is about labour and recognition. Chiikawa takes on a subjugation job in tears; Hachiware looks at the situation clearly and chooses to be positive anyway. Usagi is bound to nobody, and Momonga will not go home until somebody says they are cute. The contrast between the ones who demand recognition and the ones who can do without it is put in front of you again and again inside very short episodes. In the island arc — the Siren arc, the basis of the film — the same contrast comes back in a heavier form. Hitoha captured a mermaid to save a friend who was dying; Siren attacked the islanders indiscriminately, believing her own kind had been eaten. The motive is the same on both sides: not wanting to lose what matters. The only difference was who each of them had drawn inside the line. Jiro Shima, standing between them, changed the situation with wits rather than force, and at the end Chiikawa stops pressing for the truth. Ending with nobody able to be cast as the villain is what has kept the island arc being talked about.

🍡 Chiikawa: MBTI ISFP, attachment anxious
Crybaby, kind and hardworking. A small person who challenges both subjugation and weeding tests with tears streaming down his face.
MBTI radar (ISFP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Chiikawa is ISFP × anxious
Tears and action come out ahead of words — an ISFP of introverted feeling (Fi), living whatever they feel exactly as they feel it. The strong fear of being separated from Hachiware, and the way they fall apart whenever they are left behind, is the anxious type exactly: the fear of losing what matters is always there in the chest.
🍡 Hachiware: MBTI ENFP, attachment secure
"Do something!" is my motto. A blue hoodie who loves cameras and songs and lights everyone up with positivity and curiosity.
MBTI radar (ENFP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Hachiware is ENFP × secure
They dive into anything new with a delighted shout and turn whatever occurs to them into a song — an ENFP of extraverted intuition (Ne), facing towards possibility.
🍡 Usagi: MBTI ESTP, attachment avoidant
The embodiment of freedom, living with "Ura!" and "Yaha!" He is not bound by anyone, but in times of crisis he moves faster than anyone else.
MBTI radar (ESTP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Usagi is ESTP × avoidant
The body moves before the thought, and everything goes into whatever is fun in this exact moment — an ESTP of extraverted sensing (Se). No pack, no explanations, and an appearance only when the mood takes them. A sense of distance that never opens the inside to anyone: the avoidant type, textbook.
🍡 Momonga: MBTI ESFP, attachment anxious
I won't go home until someone says, "You're cute." The personification of frankness, who does not hide his thirst for recognition.
MBTI radar (ESFP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Momonga is ESFP × anxious
The speed and the staging it takes to stay at the centre of attention — an ESFP of extraverted sensing (Se) who shines only with an audience. The demands that never stop — praise me, look at me, say I am cute — are the hunger of an anxious type who cannot hold themselves together once the recognition stops.
🧜 Siren: MBTI ENTJ, attachment fearful-avoidant
The master of the song attacked the islanders indiscriminately, believing that his friends had been eaten. The world is only within you.
MBTI radar (ENTJ dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Siren is ENTJ × fearful-avoidant
She moves vines with a song, commands the mermaids and takes the island — an ENTJ with extraverted thinking (Te) to the fore, allocating force backwards from the goal.
🍃 Hitoha: MBTI INFJ, attachment fearful-avoidant
An islander who captured a mermaid to keep his friend from dying. A line crossed by kindness.
MBTI radar (INFJ dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Hitoha is INFJ × fearful-avoidant
She believes the legend, and assembles and carries out a procedure for one single purpose — an INFJ built around introverted intuition (Ni). Everything Hitoha did was aimed at one thing: saving a friend who had been wounded almost to death.
🌱 Futaba: MBTI ISFJ, attachment anxious
An islander who survived by eating mermaids. The silence that cannot be spoken about by those who have been saved.
MBTI radar (ISFJ dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Futaba is ISFJ × anxious
She looks at what the other person is stuck on before moving, and answers with concrete care — an ISFJ of introverted sensing (Si) and extraverted feeling (Fe). Futaba takes on guiding visitors around the island together with Hitoha, and helps Chiikawa and the others in one way or another throughout.
📚 the second-hand bookseller: MBTI INFP, attachment avoidant
A quiet bookworm who lives next to Momonga. It's more about being there than words.
MBTI radar (INFP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why the second-hand bookseller is INFP × avoidant
They keep an inward standard quietly and engage without adding words — an INFP of introverted feeling (Fi) and extraverted intuition (Ne). The grounds for an avoidant reading lie in the shape of the engagement itself.
💪 Dekatsuyo: MBTI ISFP, attachment secure
"Something big and strong." Although they are a kind of dangerous species, they are peaceful and docile.
MBTI radar (ISFP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Dekatsuyo is ISFP × secure
They hold real power and choose by their own feel when to use it — an ISFP of introverted feeling (Fi) and extraverted sensing (Se). The grounds for a secure reading are that the strength and the calm sit together.
🏪 Jiro Shima: MBTI ISTP, attachment secure
The owner runs a one-man shop on the island. He turned the tide of the war around with his wisdom and spicy curry.
MBTI radar (ISTP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Jiro Shima is ISTP × secure
They look at the situation and assemble a solution out of whatever is to hand — an ISTP built on introverted thinking (Ti) and extraverted sensing (Se). Jiro Shima runs a shop on the island alone, and not a busy one, and moves accurately only when there is a crisis.
🌰 Kurimanju: MBTI ISTP, attachment secure
Adults who are knowledgeable about alcohol. Although he loves drinking alone, he doesn't leave his juniors alone.
MBTI radar (ISTP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Kurimanju is ISTP × secure
They take their own comfort as the measure and get through only what is necessary, without fuss — an ISTP of introverted thinking (Ti) and extraverted sensing (Se). Kurimanju is drawn as an adult character with a drinks qualification, and values time drinking alone above everything.
🦦 Rakko: MBTI ISTP, attachment secure
The most powerful person in the subjugation ranking. I have a sweet tooth and go crazy when it comes to sweets.
MBTI radar (ISTP dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Rakko is ISTP × secure
They read a situation with the body and move by the shortest route at the moment it is needed — an ISTP of introverted thinking (Ti) and extraverted sensing (Se). Rakko holds the top rank in the subjugation tables and is never once shown showing it off.
🦁 Shisa: MBTI ESFJ, attachment secure
Polite super part-time worker. A hard worker who sets the stage with politeness.
MBTI radar (ESFJ dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why Shisa is ESFJ × secure
They read how the other person is doing and step in early so that nothing stalls — an ESFJ with extraverted feeling (Fe) as the dominant. Shisa works enough to be called a super part-timer, and is unfailingly polite while doing it.
👜 the Pochette Armour: MBTI ISTJ, attachment avoidant
A craftsman who makes and sells cute products. Armor that speaks more with its goods than its words.
MBTI radar (ISTJ dominant four axes + attachment stability)
Big Five radar (five factors + hidden-side axis)
Why the Pochette Armour is ISTJ × avoidant
They keep to the procedure and go on making things to the quality they set — an ISTJ of introverted sensing (Si) and extraverted thinking (Te). The Pochette Armour makes cute goods and sells them.
