Eua (エウア) is a mysterious being similar to Hanyuu that appears as one of the main antagonists of Higurashi: When They Cry – GOU and Sotsu.

While the character debuts in the story in Satokowashi-hen Part 3, she was unnamed until the official site added her profile on March 11, 2021 shortly before Satokowashi-hen Part 6 aired.


A woman with horns not unlike Hanyuu's. Calls Rika her "cat". Awards Satoko with the power to live in loops to provide her with entertainment. Satoko calls her "Eua", but her true name and nature are unknown.

(Taken from the Gou website.)


Eua has purple hair in a hime cut and has a silver horseshoe-shaped pair of horns floating around her head. She wears a shrine maiden outfit with a green sash adorned with a medal and white socks with wooden sandals. In her hand she holds a shakujou.


Eua speaks in a condescending tone and refers to humans as "child of man". She has a tendency to laugh and giggle when she's entertained by something, most especially because of Satoko's actions. Eua draws a twisted satisfaction from seeing people suffer, most exemplified when she forces Hanyuu to watch as Satoko tortures Rika in one world.


Eua can give humans the power of time looping, allowing them to travel between Fragments. Due to her power not being imperfect like Hanyuu's, humans granted the power of time looping by Eua fully retain their memories from the fragments.

In Kagurashi, Eua is capable of conjuring powerful balls of energy and can restrain people with bindings made of energy. She is also seen disappearing in the blink of an eye, telekinetically controlling her staff and a variety of other objects, and stopping people in place.


It is currently unclear as to who she is or where she came from, but she seems to recognize Satoko from another world with a "red sea". Eua describes herself as a nameless being and decided to call herself "Eua" after asking Satoko to create a name for her, getting "ehs", "oohs", and "uhs" in response.

In Kagurashi, Eua refers to Hanyuu as her "failure" and "part of her", and refers to herself as the "original"[2], though it is currently unknown what the exact relationship between the two is. An interview says that Eua is the "perfect" version of Hanyuu.[3]

Hearing Satoko's wish to create a world where Rika can stay by her side, Eua bestows her with the power of time looping, similar to the one Rika has, except Satoko will be able to retain her memories when she dies unlike Hanyuu's power.



Satoko Houjou

Eua regards Satoko as an old friend, referring to her with the names "Vier", "Mitsuyo", and "Anomalous Spinal Cord Specimen LD3105". She claims that Satoko has forgotten who she is after millions of years. Eua derives a lot of entertainment from Satoko's actions in the various Fragments she goes to and is very fond of her.


Eua's exact relationship with Hanyuu is currently unknown, however Eua refers to Hanyuu as her "failure" and a "part of her", and implies that Hanyuu was created from Eua given that she refers to herself as "the original".[2] In Higurashi no Naku Koro ni Mei, Eua's "birthday"[1] is even the same as Hanyuu's, August 1.

Role in the Story

Higurashi Gou and Sotsu

Eua has appeared as a shadowed figure in the Gou opening from Onidamashi-hen Part 2 to Satokowashi-hen Part 1. Her actual appearance is revealed in the opening of Satokowashi-hen Part 4.


When Satoko returns to Hinamizawa in 1988, she hears a sound coming from the ritual warehouse near the Furude Shrine and walks into it. Satoko hears the sound emanating from the Oyashiro-sama statue and touches it to reveal a horn-shaped object that transports her to the Sea of Fragments, where Eua is introduced standing before her.

Eua seems to recognize Satoko as an old friend and calls her by several names, regretting that Satoko doesn't seem to remember her. She knows of Satoko's wish to go back in time and fix her friendship with Rika, offering to grant her the power of time looping. The woman stipulates that Satoko must die for it to work and that it has a cost, but she won't mind so long as she's entertained by what Satoko does. Though Satoko is reluctant and confused, Eua sends her back to 1983.

As Satoko loops repeatedly trying to stop Rika from wanting to go to St. Lucia, Eua is entertained by Satoko's actions. After one of Satoko's many attempts, Eua explains Rika's past looping experience to Satoko and allows Satoko to view the Fragments that Rika has experienced throughout her 100 years. After Satoko finishes, she asks if Eua can bestow the same time looping power onto her. The horned woman can, but she explains that the power of looping doesn't necessarily make the mind immortal. Eua bestows this power onto Satoko, making her able to retain the memories leading up to her death; unlike Rika and Hanyuu's own powers. She also grants Satoko the power to go to the same Fragment the original Rika goes to, so long as Satoko dies after Rika.

After Satoko experiences several loops, she asks for a name for the horned woman, wanting to have an easier time referring to her. The woman proclaims that she's nameless and asks Satoko to pick a name for her. Satoko struggles to think of one, and the woman decides to name herself Eua after Satoko's grunts of speculation.

Satoko's loops manage to reform Teppei into a better person. Eua reminds Satoko that the accumulation of memories is irreversible, and each new loop will make the memories grow stronger; Teppei remembering previous Fragments might be a burden to Satoko going forward. Satoko doesn't mind however, as she can use Teppei to great effect. Satoko expresses her desire to make Rika pay for wanting to leave Hinamizawa despite being Oyashiro-sama's priestess, and Eua decides that Satoko is the new Oyashiro-sama and will be carrying out her own curse.


Eua and Satoko watch a Fragment of Rika and Hanyuu speaking in the Sea of Fragments after Rika's suicide. When Satoko complains of still feeling pain from stabbing herself in the neck, Eua comments that Hanyuu's memory loss power makes her a failure. Later, Eua reminds Satoko that Hinamizawa Syndrome affects people who are far from the queen carrier or are experiencing mental stress, which Mion has never faced in any world because of her duty as the next Sonozaki family head.


Satoko continues planning to make Rika suffer. Eua warns her that if she ever dies before Rika, then Satoko will go to a Fragment where Rika doesn't exist and was never born. Satoko accepts these conditions.

Eua continues to be entertained by Satoko's antics, especially her tricking Rika into thinking Satoko's abusive uncle returned and all of the later charades Satoko pulls off.

Satoko's human and witch sides begin coming into conflict when she attempts to kill Teppei. Eua enjoys herself watching them fight and stops the human side when she tries to run away. Eua allows the witch side to seemingly kill the human side.

Eua continues to enjoy the witch Satoko's antics. After Satoko and Rika's deaths, Eua acknowledges Hanyuu and comments on her being unable to view the Fragments, asking what she plans to do now.


Eua enjoys watching a deranged Keiichi wreak havoc at Angel Mort when Hanyuu suddenly appears, announcing that she's finally found her. Eua shows her the Fragment where Satoko gets up after playing dead, horrifying Hanyuu since she now knows Eua gave power to Satoko. Eua once again calls Satoko "Vier", regretting that she lost her memories, but is still entertained. Hanyuu and Eua exchange blows, however Eua restrains Hanyuu while referring to her as another part of her. She forces Hanyuu to watch the next Fragment, where Satoko performs the watanagashi on Rika. Eua is greatly entertained by Hanyuu's despair and taunts her, asking what Rika will do now.

Eua watches as Rika and Satoko duke it out across multiple Fragments. When Hanyuu tries to escape her restraints, Eua stops her by stabbing her with her staff. Eua is still waiting for Hanyuu to display her miracle, promising she will do whatever she says if she succeeds.

At the final confrontation where a superpowered Rika prepares to finish off Satoko with the Onigari-no-ryuuou, Hanyuu breaks free from her restraints and rushes at Eua, but Eua stops her with her staff again and says Hanyuu needs to show her miracle quickly or else she'll disappear. Hanyuu declares it's her friends who helped her see miracles and Eua grows tired, dropping several pieces of furniture on her.

Eua's miniaturized form after her horn is cracked.

Hanyuu emerges and declares that a miracle will never side with Eua, and when Rika discards the Onigari-no-ryuuou in the human world, Hanyuu obtains it and uses it to attack Eua. Hanyuu proclaims that her friends are much stronger than Eua realizes, and the horned woman commends her. Hanyuu successfully strikes Eua and creates a crack in her horn, and Eua cackles and au-au's as she shrinks to a childlike form. Eua admits that Hanyuu has won and disappears.

Higurashi Gou (manga) and Meguri

When Satoko returns to Hinamizawa in 1988 to reunite with the club, she recalls memories of the club as teenagers. Eua suddenly whisks Satoko away to the Sea of Fragments and, understanding that Satoko wants to return to June of 1983, says she can grant that wish.


  • Eua's name on the official anime website used to be "Uhmera", but it was changed after March 11, 2021.
  • Eua's discussion with Satoko in episode 21 seemingly references other When They Cry installments Umineko no Naku Koro ni and Ciconia no Naku Koro ni:
    • She refers to Satoko as "Vier." Vier Dreissig is a character in Ciconia who bears resemblance to Takano. She also refers to her as "Mitsuyo", which can be read as 34; this coincides with the similar naming schemes of Vier and Takano, whose names can also be read as 34.
    • Lastly, she says LD3105. "LD" could refer to Lambdadelta, an Umineko character, while 3105 is a Japanese wordplay that can be read as "Satoko." The same wordplay has previously been used in the Hinamizawa Bus Stop manga.
    • An interview suggests that Eua was also called "Eua" in a prior world by Satoko's previous existence and was well acquainted with her.[4]
  • Eua herself has a similar appearance to the Umineko character Featherine Augustus Aurora. They have the same hairstyle, silver horns, and a similar outfit, differing in that Featherine wears a pink dress that exposes her shoulders and cleavage. They also have different voice actors, with the latter voiced by Michiko Neya. Ryukishi07 does not confirm or deny if they are the same character, however.[5]
    • Eua has an SSR unit in Higurashi no Naku Koro ni Mei titled Theatergoer of the Annulus, while Featherine in Umineko had the title of Witch of Theatergoing, Drama and Spectating.
    • In Twilight of the Golden Witch, it is mentioned that Featherine's memory device was attacked in the past, causing her to gain a different appearance and personality. Eua's battle with Hanyuu results in a similar thing, with Eua shrinking down and saying "au, au".
  • In Higurashi no Naku Koro ni Mei, Eua's "birthday" is actually called "day of descent" (降臨日). Hanyuu and Tamurahime no Mikoto's birthdays follow the same format.

  2. 2.0 2.1 Kagurashi-hen Part 3
  3. Animate Times Keiichirou Kawaguchi Interviews
    Eua was introduced as a new character, but was there anything that Ryukishi07 asked you to do with her?

    Kawaguchi: We hadn’t received any details about Eua, so we weren’t sure what kind of person she would be at first. I think I remember we talked about whether or not she had a cane after I received the rough drawings… Ryukishi07 described her as someone like a perfect version of Hanyuu.

    There are many things that resemble Hanyuu in her appearance, aren’t there?

    Kawaguchi: That’s right. I remember being surprised to see the horns floating around her head. Maybe Hanyuu will be able to detach her horns when she grows up too *laughs*

  4. Higurashi: When They Cry- GOU Behind the Secrets
    Kanai: Ah, I see. But about Eua, she's called Eua because Satoko goes "Eh...Ooh...Ah..." right? But why do you think she's called Eua?

    R07: Umm...That's...

    Kanai: You can't tell us?

    R07: No. I can reveal that, actually. So actually, Eua was called Eua in her last world as well.

    Kanai: So it wasn't just a coincidence...?

    R07: She recognizes that in the previous world, the Satoko's previous existence (存在) called her Eua as well.

    Kanai: I see...

    R07: So, in this new world, it's actually not her first time meeting Satoko, but Satoko doesn't remember. So she's disappointed. And she's like, "Well, then just call me whatever you want," and Satoko just happens to go, "Eh...Ooh...Ah..." and Eua's like, "You actually remembered me! You really are you after all!"

    Kanai: So that's how it was...

    R07: But obviously Satoko doesn't understand and is just like, "Hmm..." So as a god, Eua is really pleased with this response, but as a human, Satoko just thinks, "Well, okay...If she's happy with Eua, then that's fine..." That's kind of a hidden backstory I have for it.

  5. Higurashi Gou SP Live Talk
    Host: Let's see... What's the deal with Featherine?

    R07: *bursts in laughter* That's some hot topic right there.

    H: Wait, first, am I correct to assume it is her?

    R: Well... indeed, there is a character in Umineko called Featherine that is very similar to that character. But for that character, voiced by Hidaka Noriko, her name is not Featherine.

    H: So you say her name is not Featherine?

    R: She is (not) Featherine (あれはフェザリーヌさんでは...he never finished that sentence)"
