Duel in the Mist

i. The Fool's Fall

ii. The world this song lives in — a bridge for anyone arriving without a map

(If you already play Genshin Impact, skim this; if you've never touched it, this is your way in.)

Genshin Impact is a vast open-world game set in Teyvat, a continent of seven nations, each modelled on a real-world culture and ruled by a god called an Archon. Inazuma is its Japan-inspired nation — an island shogunate of thunder, torii gates and sakura, ruled by the Electro (lightning) Archon. That ruler's public face is the Raiden Shogun, who has declared that her nation will pursue "Eternity" — a frozen, changeless perfection — at any cost, hunting down anyone who carries the divine power called a Vision.

Here is the turn the music is built on (story spoiler, and the reason the theme exists): the Raiden Shogun the player fights is a puppet — a body the true Archon, Ei, built to rule in her place while she sealed her real self inside a plane of meditation, chasing a changelessness that costs her everything human. You meet this music at her sword's edge, and most directly in the Mystic Onmyou Chamber, the arena of the recurring boss fight against that god-made-machine. So the piece is not "a battle." It is the sound of a god at war with her own shadow — which is exactly why it rewards a dive.

iii. The maker — Yu-Peng Chen, the man who gave Teyvat its voice

You cannot talk about this cue for thirty seconds without talking about the person who wrote it, because for the first four years of this game, the sound of the whole world was one composer's hand.

Yu-Peng Chen (陈致逸, Chén Zhìyì) trained at the Shanghai Conservatory of Music and came up through film and television scoring; he names Bach and Rachmaninov as first loves and was classically schooled. From 2019 to 2023 he was the lead music producer at HOYO-MiXthe in-house music studio of the developer HoYoverse / miHoYo. Per Wikipedia's Music of Genshin Impact, he was the sole composer of the game's world-area soundtracks up until the second Inazuma album, Islands of the Lost and Forgotten (2022), when other composers joined — a sourced claim, not a flourish (to be re-verified before any remake). Mondstadt's wind-swept freedom, Liyue's mountains, Inazuma's thunder, the first reach into Sumeru — one person built those musical nations.

His method is the part worth carrying out of the game entirely: he scores a place by marrying its folk tradition to a Western orchestra. For Liyue (an Imperial-China-inspired land) he reached for Chinese folk material — the pentatonicfive-note scale, the erhua two-stringed bowed fiddle, the plucked guzheng — and set it inside Romantic harmony and a full orchestra. For Inazuma he swapped the palette to Japan, which is what you are hearing in "Duel in the Mist." His own creed is plain: "the more simple and ingenious the music is, the more it can move the audience," and "there is no work more important than this."

On 12 September 2023 he announced on Weibo and Bilibili that he was leaving HOYO-MiX — partly to make room for the studio's younger composers, partly to chase his own work. Players treated it as the departure of a major composer, not a staffer. He had earned that: he is the reason a free phone game has a body of orchestral music people attend concerts to hear. Erasing him to a credit line would be the single most dishonest thing this article could do.

iv. The record — Realm of Tranquil Eternity, and a name that is the whole story

"Duel in the Mist" is track 59, the third disc — "Battles of Inazuma" — of _Realm of Tranquil Eternity_, the first Inazuma album (released 22 September 2021, 62 tracks across three discs, composed by Yu-Peng Chen of HOYO-MiX). The album's title is already Ei's obsession stated aloud: tranquil eternity, the changelessness she will freeze a nation to keep.

But the track's own name is the better door, and it is a name English-only listeners never get to see. "Duel in the Mist" is a loose localisation. The Chinese title is *斩雾破竹 (Zhǎnwù Pòzhú) — literally "cleave the mist, split the bamboo." The second half, 破竹 (pòzhú), is lifted straight from the classical idiom 势如破竹 (shì rú pò zhú) — "force like splitting bamboo," the image of a momentum so total that once the first node cracks, the whole stalk runs open by itself: unstoppable advance. The Japanese title keeps the same four characters, 斬霧破竹. So the name is not "two people fight in fog" — it is cutting through confusion with irresistible force*, which is precisely the dramatic shape of the cue and the shape of the fight. The localisation traded a Chinese idiom for an English atmosphere; the dive gives it back.

v. The work, dissected — a theme that refuses to hold still

A song you replay is a fixed object. A battle theme is not. The first thing to understand about "Duel in the Mist" is that it is adaptive — it lives as a family of versions, not a single cut.

• It is built to escalate. Combat music in this game is layered and state-driven, written so the

orchestration thickens and the percussion drives harder as the encounter intensifies. The "same" piece you remember is several states of one piece, swapped under you in real time as the fight turns.

• The theme has a sibling. The canonical credits note that "Duel in the Mist" shares its theme with

a second Mystic Onmyou Chamber cue — the same melodic material, re-scored for a related moment. That is the leitmotifa short recurring musical idea tied to a character or situation doing its proper job: a god's signature that returns transformed when you meet a different face of her. The same motif, a changed character. Following that recurrence is the close-listening reward.

• The palette is Japan, played by Japanese masters. This is where §vi takes over — but in the sound

itself you are hearing the bright pluck of the kotoa long Japanese zither, the dry snap of the tsugaru-shamisena three-stringed lute, the percussive northern style, the reedy cry of the shakuhachian end-blown bamboo flute, and the architecture-shaking roll of taikoJapanese drums — woven into a full Western orchestra. Thunder and ceremony, the nation written into the instruments.

• The drive is the meaning. It is fast, propulsive and relentless by design — an official MV exists to

showcase exactly that intensity. The title already told you why: force like splitting bamboo, a fight against something that will not stop.

vi. The hands behind the glass — bring them to the table they built

Game audio at this level is made like film, by a long bench of named, specific people — and the credit sheet (published via NetEase Cloud Music, the canonical wiki, and the album's own liner) deserves to be read out, not compressed. For "Duel in the Mist" specifically:

• Composer & orchestrator — Yu-Peng Chen (陈致逸).
• Taiko — Kodo (鼓童). Not a session player: Kodo is the internationally famous taiko ensemble,

founded in 1981 and based on remote Sado Island, who live communally and have spent four decades making taiko a concert-stage art across the world. That ceremonial drum-weight under the cue is one of the most storied percussion groups alive — a door worth walking out of the game to find.

• Tsugaru-shamisen — Yutaka Oyama (小山 豊) and Sayo Komada (駒田 早代). Oyama is a celebrated

inheritor of the Oyama tsugaru-shamisen lineage who has spent his career carrying that northern, percussive style into new music — exactly the kind of master HOYO-MiX flew the score to, rather than faking with a sample.

• Koto — Kasumi Watanabe (渡邊 香澄). Shakuhachi — Mamino Yorita (寄田 真見乃).
• Orchestra — the Tokyo Philharmonic Orchestra (東京フィルハーモニー交響楽団), one of Japan's major

orchestras, conducted across the album by Hirofumi Kurita (栗田 博文).

• Recorded at Shangri-la Studio and SoundCity (Tokyo), engineered by Yuta Tateishi,

Haruki Saito and Koji Suzuki, supervised by Satoshi Chiba and Ryo Yamamura of Sony Music Publishing (Japan), with co-production by Sony Music Entertainment (Japan) — and mastered by Simon Gibson, a name a film-score listener will know from Abbey Road Studios in London.

Read that chain again: a Chinese studio and composer score a Japan-coded nation by hiring Japan's living traditional masters and a major Tokyo orchestra, record it in Tokyo, and master it in London. That supply chain — not a preset, not a sample library — is why a phone game's boss theme sounds the way it does. The famous name is the Shogun; the people who actually made the sound are on this list.

vii. What is this similar to

The richest relatives sit in three directions, and all three give you somewhere real to go.

Inside Teyvat — the composer against himself. The truest comparison is Yu-Peng Chen's own region and battle music, because the instrument swaps but the hand does not. Play "Duel in the Mist" against his Liyue combat and region cues (Chinese instruments, the same Romantic-orchestral frame) and you hear one composer re-clothe his own writing nation to nation. Then play it against its sibling Mystic Onmyou Chamber theme, where the shared motif returns re-scored — the composer comparing himself to himself across a single encounter. That is the most rewarding listening the piece offers, and it needs no outside reference at all.

The orchestral-epic lineage it descends from. This cue belongs to a deep, specific tradition of through-composed, percussion-driven, choir-shadowed combat music. Its ancestors are audible: the Hans Zimmer school of low-string ostinato and building percussion, and the older choir-as-fate gesture that runs from Carl Orff's _Carmina Burana_ (1936) through decades of trailer and game music. If "Duel in the Mist" feels like a final boss you fought years ago, that is lineage, not coincidence.

The cross-cultural door — walk it. Because the cue is carried by Kodo and a tsugaru-shamisen master, the honest "listen next" leaves the game entirely: go hear Kodo's own concert recordings, or Yutaka Oyama's tsugaru-shamisen work, and you find the living traditions the score borrowed — taiko as a staged art, the shamisen's northern percussive attack — sounding exactly as old and exactly as alive without a boss attached. The game is a doorway into a centuries-old Japanese performance practice; the people in §vi are where it leads.

And the layer that, for an invented world, is half a theme's life: the flood of fan orchestrations, metal covers, and piano re-scores of this cue. For an imaginary place, that community re-performance is where the music keeps growing — each version another iteration of a theme already built to mutate.

viii. Meaning — music as characterisation (an instrumental cue)

This is an instrumental piece — no sung text, so there is no lyrics block; its "language" is the leitmotif. Its meaning is dramatic, and the score does narrative work dialogue cannot: the relentless drive says implacable; the Japanese-orchestral grandeur says a nation's god, not a monster; the shared motif that returns in the sibling cue says this enemy is not who she appears to be. By the time you understand the Shogun was a mask, the music has already told you — that is a score characterising a villain in sound, and "斩雾破竹" (force like splitting bamboo) names the exact feeling it is built to give the player: an advance that cannot be stopped, against a god trying to stop time itself.

ix. Era, scene & afterlife

The scene. This belongs to the moment, around 2020, when game music became a serious orchestral art form with a global concert audience — scores performed in halls and streamed as standalone albums, decoupled from playing the game. Yu-Peng Chen's Genshin work is a landmark of that turn, and the use of a major orchestra plus traditional soloists is the proof on the record.

The afterlife. "Duel in the Mist" long ago left the boss room. It turns up in official HOYO-MiX orchestral concerts, is endlessly re-performed by the community, and is loved by people who have never fought the Raiden Shogun — the surest sign of how far game scoring has travelled.

### Pocket of wonder The album is named Realm of Tranquil Eternity, and "eternity" is precisely what the Shogun would freeze a nation to win. So the most violent piece on the record is, underneath, about a god so afraid of change that she built a puppet to rule in her place and withdrew into a dream of stillness — and the music refuses to be still, escalating through states and handing its theme to a sibling cue. The most stillness-obsessed character in the game has a theme that cannot stop moving. The score disobeys the eternity it is named for. That contradiction is the character, written in sound.
