  • Yasuo is voiced by Liam O'Brien.
  • The flute Yasuo plays in his dance emote is most likely a Shakuhachi (harmonica for High Noon, wind controller for PROJECT).
  • Yasuo's sword's length is about tachi's or even ōdachi's; however, he wears it cutting edge up like the shorter katana.
  • Yasuo is Japanese masculine given name, rendered as 康夫 "peaceful man" in Japanese localization.
    • Yasuo is not his birth name, but was given to him when he joined the sword school in an effort to steady his wild nature.
    • Since his brother is named Yone 米 "rice", Yasuo's birth name might be likewise mundane (e.g. Serizawa Kamo's adult name 鴨 means "duck").
  • Way of the Wanderer Way of the Wanderer's doubled critical strike chance references Samurai gameplay portrayals in video games, or any high damage-based role meant to deal burst damage to the opposition.


YasuoSquare Nightbringer Yasuo [S|L]


YasuoSquare Classic Yasuo [S|L]
  • He references and resembles Miyamoto Musashi and/or Haoumaru from Samurai Shodown via his iconic ponytail design shared with individuals, where in the former's case it is usually a case of a common design for him in fictional media.
    • Haoumaru himself of course, is also based on Miyamoto Musashi as well. Another note of his is how his Steel Tempest Steel Tempest in the Chinese servers is written/dubbed as 斬鋼閃 (Zhǎngāngshǎn, lit. Slashing Steel Flash), which when read in Japanese with the same characters (Zankousen) is exactly the same name as one of Haoumaru's attacks.
    • Yasuo's taunt in most of his skins (save for Nightbringer) involves him drinking from his bamboo flask, then spitting on his blade to "bless it", a habit that's also shared by Haoumaru in his home series' battle intros.

YasuoSquare PROJECT: Yasuo [S|L]
  • He is from an alternate future in which he was cybernetically augmented as part of the PROJECT Initiative.
  • Master YiSquare PROJECT: Yi [S|L] describes him as:
    • "Tempest, a blossom caught in drift, fluid form. He speaks. 'Death is like the wind'... he is a storm, blade howling... 'always by my side'... the eternal wanderer."
  • If one tells AsheSquare PROJECT: Ashe [S|L] they fight for 'truth' she'll say the following:
    • "We're on the right path."
  • His gear includes:
  • He was originally convinced as 'Cyber Ops Yasuo'.
  • He references Gray Fox and/Samuel Rodrigues or Raiden, all from the Metal Gear series. The last was further referenced in Yasuo's recall animation pose that is similar to Raiden's when he battled Vamp's robots in Metal Gear Solid 4: Guns of the Patriots, where he holsters his blade by the pommel underneath his foot.
  • He has one less basic attack animation compared to his other skins, and all three basic attack animations are different from all other skins despite the same animations on all non-recall animations (barring Nightbringer Yasuo).
  • His voice loses the sound effects and his face can be seen when he jokes, taunts, or dances, where it is shown as normal without any altercations unlike with the other PROJECT skins.
  • His sword blade turns olive-yellow while Last Breath Last Breath's bonus armor penetration is active, as opposed to a subtle aura covering his sword.
  • In this skin, he drinks from a fuel-container which may contain a substance suitable for cyborgs.
  • He shares this theme with AsheSquare Ashe, EkkoSquare Ekko, FioraSquare Fiora, JhinSquare Jhin, KatarinaSquare Katarina, LeonaSquare Leona, LucianSquare Lucian, Master YiSquare Master Yi, VayneSquare Vayne, ViSquare Vi, and ZedSquare Zed.
YasuoSquare Blood Moon Yasuo [S|L]

  • The flask he normally drinks from is instead turned into a gourd in this skin; despite wearing a mask in this skin like with PROJECT: Yasuo, Yasuo does not remove it during his taunt to drink.
YasuoSquare Nightbringer Yasuo [S|L]
  • During the development period, the skin was called "Demonblade Yasuo".
    • This development name is shared with TryndamereSquare Demonblade Tryndamere [S|L], which implies that Nightbringer Yasuo may have originally been intended for the "Demonblade" theme.
  • He shares this theme with RivenSquare Dawnbringer Riven [S|L].
  • He resembles Nightmare from Soulcalibur.
  • The flask he normally drinks from is instead turned into a potion vial in this skin.


  • Yasuo is an Ionian swordsman accused of treason for allegedly murdering an Elder. He is being hunted down across the island continent the killer employed a wind technique, one that only Yasuo has mastered in the present day.
    • He crossed paths with TaliyahSquare Taliyah while on the run, teaching the Shuriman stone mage how to control her powers. When they parted ways, she gifted him a long thread from her handspun wool tunic (the same one he uses to tie his hair up)
    • Yasuo suspects RivenSquare Riven of being the Elder's killer ("Wait, that Broken Wings technique... huh", "Huh, Broken Wings three swift strikes... ", "Another Wind Slash wind blade?", "Who taught you Wind Slash that?")
