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 khakkara.


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 can give humans the power of time looping, allowing them to travel between Fragments. Due to her power not being imperfect like Rika'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 bind people with bindings made of energy.


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", though it is currently unknown what the exact relationship between the two is.

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 loops. 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", imply the two are connected in a some way.

Role in the Story

Higurashi no Naku Koro ni Gou

Eua's grin in the first (top) and the second (bottom) versions of the opening.

Eua has appeared as a shadowed figure in the 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.

Higurashi no Naku Koro ni Sotsu


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's discussion with Satoko in episode 21 potentially 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.
  • 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. On a livestream, Ryukishi acknowledged the similarities and stated that the then-unnamed Eua's name is not the same as Featherine's but does not comment on them being the same character or not.[2]
    • On a later interview, Ryukishi said that people who played Umineko or some of 07th Expansion's other works can "possibly interpret her words as little easter eggs that hint at some of those other worlds, a little message".[3]
  • An interview suggests that Eua was also called "Eua" in a prior world by Satoko's previous existence.[3] She refers to this existence as Vier in Gou[4] and again in Sotsu[5]. She seems disappointed that Satoko seemed to have forgotten her, but later seems rather delighted when Satoko comes up with a name for her. Ryukishi07 explained Eua's emotions in the interview:
"Eua was called Eua in her last world as well. 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!".

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.
