Orobashi no Mikoto (Japanese: オロバシノミコト; Chinese: 远吕羽氏尊)[1] or Orobaxi (Chinese: 奥罗巴斯),[Note 1] also referred to as the Watatsumi Omikami (Japanese: 海祇大御神 "(Great) God of the Oceans"),[2] was an ancient dragon-like serpent god that was defeated by Raiden Ei at Yashiori Island. The Musoujin Gorge is the scar left by the god when she delivered a blow from her Musou no Hitotachi, slaying the serpent.

The remnants of Orobashi can be seen throughout the island, with its skull located at Serpent's Head. Its lingering power has resulted in the Tatarigami, a phenomenon on the island that causes natural disasters and can drive people on the island mad.

The residents of Watatsumi Island and their leaders, the Sangonomiya Clan, worship Orobashi, as it taught them how to farm and smelt after discovering them in the Dark Sea.[1] Therefore, the people of Watatsumi Island are very grateful towards Orobashi and worship it as their guardian deity.[3]



At some point in time, Orobashi fled from an unknown region[Note 2] to Enkanomiya — the abyssal nation of ever-night[Note 3] — in the Dark Sea.[4][1][5] There, it found a group of "abandoned people" living at the bottom of the ocean,[Note 4] at the mercy of the Dragonheir of the Depths. Taking pity on them, the god took them in as its own[1] and defeated the Dragonheir of the Depths.[5] it broke off the coral that grew from its body — a manifestation of its power — to create Watatsumi Island so its people could live above the surface again.[6] Orobashi guided the residents of Watatsumi Island and taught them how to farm and smelt, for which they were deeply grateful and worshipped it.[7]

During the Archon War, the Inazuma archipelagos were united under Raiden Makoto's rule, with her twin sister Ei acting as her kagemusha (body double). All those who dwelt within Inazuma were content with their lot and did not seek to take what was not theirs, lest they be eradicated by the Raiden Shogun.[6]

When the Sacred Sakura Cleansing Ritual was developed, those performing the ritual were to beg forgiveness from both the Narukami and the Watatsumi shrines before beginning the ritual,[8] suggesting that Orobashi may have been worshipped by people from other islands for a time.

Attack on Yashiori Island and Death

For many years, Orobashi respected the boundary between Watatsumi Island and the Narukami and both lived in peace.[6] The peace was broken at some point during the archon war thousands of years ago,[9] when Orobashi invaded Yashiori Island without warning and set off a brutal war between their own people and the Shogun's. The war caused great suffering and many casualties on both sides, among them Ei's lieutenant Sasayuri.[6]

At the end of the war, Orobashi was slain by the Raiden Shogun on Yashiori Island, using her signature Musou no Hitotachi swordsmanship. The killing blow created a great rift, splitting the island in two, and Orobashi's remains still rest throughout the island.[10] Orobashi's champion Touzannou (later known as Akuou) was also slain by this slash.[11] The shrine maiden Mouun from the Yuna Clan was killed by the subordinates of Sasayuri while in retreat, whereas her sister Ayame went missing in action.[12]

Its lingering hatred became the Tatarigami, which the Shogunate later utilized to create the Mikage Furnace.[13] Following Orobashi's death, the main shrine on Watatsumi Island was subsequently abandoned, with a new shrine being built elsewhere.

The true motive behind this attack remains mysterious, as Sangonomiya has an extreme lack of written historical material. But it is said that people of Watatsumi Island experienced a long famine and they were able to persuade Orobashi to invade Yashiori Island and claim it for their own.[14]


According to Sangonomiya Chronicles, a text written by Shogunate historian Kujou Michizane, the people of Sangonomiya have recognized the Inazuma Shogunate as the rightful ruler following the death of the Great Serpent. However, while recognizing the Raiden Shogun's authority, the Sangonomiya have continued to worship Orobashi instead of the Raiden Shogun despite its death at her hands.[15] Many mentions refer to in-game document text to theorize the events which took place by different historians - therefore the accuracy of what has been written may not be entirely conclusive, or contradicts other available information.

When the Vision Hunt Decree was enacted, the Sangonomiya Clan declared war on the Inazuma Shogunate, leading to mass skirmishes between the Watatsumi Army and the Tenryou Commission.

A radical faction within the resistance, at Nathan's suggestion, sought to revive Orobashi by destroying the Narukami Pillars on Yashiori Island.[16] Unbeknownst to them, Nathan was a Fatui mole sent to sabotage the war effort by releasing the Tatarigami and hindering the resistance's chances at a quick victory.

Following the revelation of the Fatui conspiracy and the end of the Vision Hunt Decree, most of the Fatui withdrew from the island, save for a few who wished to get payback for Signora's death. Nonetheless, some Watatsumi residents find it hard to accept peace with the Shogunate, believing that doing so would meant that Orobashi's sacrifice was in vain.



  • Following the theme of gods in Genshin Impact being named after demons in the Ars Goetia, Orobashi may be named after the demon Orobas, one of the Great Princes of Hell. However, unlikely due to an already existing mythology from the east - and does not fall under an Archon name (a universal Teyvat name) which is usually born after their personally ascribed names.
    • The Chinese version of Orobaxi, 奥罗巴斯 Àoluóbāsī, can be read as Orobas, although most Chinese translations of the demon name use 歐若博司 Ōuruòbósī.
    • Orobashi (Japanese: オロバシ), is slightly different from Orobas' Japanese name, オロバス Orobasu.
  • Orobashi may also be modeled after Orochi, a legendary dragon/serpent in Japanese mythology who was slain by the storm god Susanoo.
  • In the Japanese localization, the name "Orobashi no Mikoto" is written in katakana (phonetically) rather than kanji, a convention that is typically used for gods or foreign names.
    • It is likely that "no Mikoto" (Japanese: ノミコト) would be , a title following a noun that is used for gods, emperors, and other high-ranking persons. It translates into English as "the honorable" or "the exalted."


  1. The term translated into English as "Orobashi," 远吕羽氏 (Traditional Chinese: 遠呂羽氏), has the same meaning in both Chinese and Japanese but is read as Yuǎnlǚyǔshì in Chinese and Orobashi in Japanese. As a result, most NPCs use "Orobaxi" (Chinese: 奥罗巴斯 Àoluóbāsī), which is a Chinese phonetic spelling for the Japanese Orobashi reading. Because most other localizations translate 远吕羽氏 as Orobashi, the reason for a phonetic spelling is lost; the Japanese localization does not even bother distinguishing the two names and translate them both as オロバシ.
  2. Jade Branch of a Distant Sea's description of Orobashi matches Bit of Aerosiderite's description of ancient gods who were defeated in the Archon War and fled to the Dark Sea. Combined with the fact that Watatsumi Island is currently the island closest to mainland Teyvat, this could indicate that Orobashi came from an area closer to the mainland.
  3. The "abyssal nation of ever-night" mentioned in Coral Branch of a Distant Sea likely refers to Byakuya no Kuni (Japanese: 白夜国 "Land of the Midnight Sun") and not Orobashi's original land.
  4. It is unclear what happened to the Oohirume no Omikoshi, whom the Sangonomiya ancestors relied on to survive the Dragonheir's attacks before Orobashi's arrival. It can be assumed that they either left their people to survive on their own or perished at some point before Orobashi appeared.
