CHUNITHM original songs and story universes are categorized under various labels. Each label has its own rules and dedicated lore, and can be identified by its unique background in-game.
The original labels in CHUNITHM are the following:
CHUNITHM's first label, focused on the fantasy genre and primarily featuring RPG composers. Its story follows an amnesiac boy named Shizuma Kurosaki wielding the legendary sword Seele Tact on his travels, gathering allies and facing evil. It is distantly connected to the Metaverse storyline, but can be read standalone.
Nine years after its conclusion, Monsieur Chapeau was added to this label, likely as a nod to composer Toby Fox's RPG work, as the story is entirely unrelated.
A label focused on idol and denpa songs. Not all of its stories are interconnected, but most characters are idols or otaku of some kind, and often include numerous pop culture references and detailed explorations of the characters' hobbies.
A number of Gumin stories are part of the "Demon Continent Akihabara" saga, featuring idols who want to turn Akihabara into their empire and spread otaku culture.
A label focused on Utaite and Vocaloid/VSynth producers. Relation is an umbrella label for a number of smaller, standalone stories, and spans a wide variety of genres, from slice of life to sci-fi and fantasy.
Some Relation characters' stories are connected, often in pairs such as Sylvias and Astraea (folern/Endmark), or Ruko Araba and Seito Maizono (Invitation/RevolutionGame).
A label focused on live and instrumental music, featuring many guitarists, pianists, other instrumentalists, and a number of artists known for Touhou arrangements.
G.O.D's story takes after fighting games, with a wide cast of musicians from different settings. Musicians in this universe have special powers, and are called to "purgatory" to fight against an evil god with the power of music. While the cast is loosely connected by the overall plot, the label is primarily character-focused, and many stories can be enjoyed independently.
The Metaverse as a whole is a label focused on electronic music. It is CHUNITHM's largest original label and contains many of the game's highest-level charts. Its main story is split into two halves, the first being the Digital Metaverse, up to CRYSTAL (and some of PARADISE).
In its story, the Metaverse is a virtual world created to house humanity after an apocalypse. Many early stories are connected in setting alone, but the story becomes more cohesive with each version, and are best read in order. The overarching story follows power struggles among programs and humans within the Metaverse, as well as its origin and the aftermath in the physical world.
The second half of the Metaverse story beginning from PARADISE. Humanity is finally ready to come back to the surface, but the returning humans are caught up in a war with the new race of synthetic humans created to fix the polluted planet, and the machines who created them. Like most of the Digital version, these are interconnected novel format stories and are best read in release order.
LUMINOUS PLUS and VERSE both use the Surface background, but their stories are independent:
LUMINOUS PLUS features the Farthest End Arc, a short arc set within the Metaverse in the distant future, in a world not yet impacted by the events of the Digital Metaverse.
VERSE's MultiVERSE Arc follows two teens on an adventure in a fantastical new world—it is currently ongoing, and its connection to the other stories is unclear.
A label focused on future bass music first added in STAR PLUS, featuring cute animal characters. Animalia is made up of slice of life stories in a world where animals can talk, set in Safari City, Gunma Prefecture. Animalia's stories contain references to each other, but can be enjoyed independently.
A label featuring composers from outside Japan, primarily the US and Asia, first added in CRYSTAL. Sibyl is a dark fantasy series about young women given powers of the four elements, and the struggles they face as a result. Many of its stories are especially tragic and gruesome, and may deal with very heavy subject matter—please take note when reading them.
The Sibyl stories in VERSE are a new starting point for the series known as the Scourge arc.
Irodorimidori is CHUNITHM's own idol series. Irodorimidori characters will not be translated or hosted here. They have their own dedicated wiki—please consult there! It's a multimedia offshoot series with some official translations out there.
A label consisting of songs written and performed by VTubers. As these are treated like collab songs and feature the artists' avatars instead of original characters, they have no stories to translate and will not be hosted here. The exception to this is Perio, an alias/character belonging to sasakure.UK who was originally featured as a Relation character in CHUNITHM's original release and later brought back under Omnibus with his VTuber debut. This story will fall under Relation.
A handful of characters have no label. This includes Chuni Penguin, whose unlockable story consists of messages from the team after each version.
Any currently untranslated stories can be found on the Japanese wikiwiki site, listed here by label.
”Dur” is a German word referring to “major” musical scales—in this case, A major. A glissando is a glide from one pitch to another. Leggiero is a direction to play with a light touch.
Translated literally from “青の死神/ao no shinigami”
A hero of legend that was said to be able to control and communicate with the Machine Gods.
Fené’s chakrams. In music terms, destra refers to the right hand while sinistra refers to the left. Arco directs that a string instrument be played with a bow rather than plucked by fingers, and legno (col legno) is a direction that players of bowed instruments should use the wood, and not the hair of the bow.
Another word used to refer to Machine Gods.
A term used to refer to “inferior” Machine Gods. They are described as having lost their proper function, and thus lose reason/intelligence and resort to indiscriminate slaughter.
“Hand-stopping”, a German-named technique that can change the sound of a horn by inserting the hand into the bell.
The titular blade. Ordinarily it is a large crystalline object, but it responds to Shizuma—who can transform it into a longsword to wield. Frequently referred by just the name Tact. The word "タクト (Takuto)" is the Japanese abbreviation for the German word Taktstock, a conductor's baton. Seelisch is also a German word, with the meanings of "psychologically", "mentally", and "spiritually". The word "Seele" is also German, similarly meaning "mind", "soul", and "(human) spirit".
Two different ways of playing music. Staccato notes are played with short, detached duration. Legato notes are fluid and continuous.
A specific type of horn that Glenn is able to shoot musical bullets from.
This term originates from the story of Omega Quintus, a mechanical creator god who remade humanity after its destruction in the early days of the Metaverse. Unlike normal humans, Paragons are a synthetic race that cannot age or reproduce, and die after a short "service life." However, they have heightened physical and regenerative abilities, and can interface more easily with technology.
Paragons were created to restore the Earth's polluted surface in preparation for humanity's return. They were initially not given emotions, but later developed their own egos, leading to the central conflict of the surface story.
真人 is read as shinjin and literally means “true human.” Machine translation often translates this word as “Masato.” The kanji 真 translates to “truth” or “reality,” while 人 is simply “person,” “people,” or “man.”
The term Paragon was chosen to match the spirit of the original term and clearly distinguish them from the Returnees and Machines. From Isabelle Yagrush Episode 8, "Synthetic humans with highly advanced physical capabilities and self-regeneration could truly be called paragons of humanity." In Japanese this is "正しく真なる人と呼ぶに相応しかった," lit. "it would be fitting to call them right and true people."
Humans born and raised in the virtual world of the Metaverse who are sent to the real world by the mainframe. Their physical bodies are generated upon leaving the Metaverse, and they grow and age like normal humans. They are part of the mainframe's plan to repopulate the Earth, bringing the old humanity back from the electronic paradise.
The term "returnee" refers to someone who returns somewhere, often after a long time away from their home.
帰還種, read kikan-shu, consists of 帰還, meaning "returning home," and the suffix 種, meaning "species" or "type."
Autonomous androids meant to oversee the Paragons' progress restoring the surface. They are humanoid in appearance, and may last for hundreds of years. Sometimes referred to as a whole as "Machinekind."
機械種, read kikai-shu, consists of 機械, meaning "machine," and 種, meaning "species" or "type."
The name etymology for the Surface Metaverse is mainly derived from two sources, with a few outliers.
The Moderate Faction arc and Bathsheba War arc derive mostly from the Bible (primarily Old Testament), with the former borrowing from Herman Melville's 1851 novel Moby-Dick as well.
This list is incomplete.
Gideon is named for a prophet from the Book of Judges. Among many things, Gideon is notable for destroying an alter to Baal, the religion instituted by Jezebel (see: Isabelle).
"Reise" is a German word meaning "journey," and comes from OG Metaverse character Pendulum Reise (default name Pendulum Alter). She is implied to be a distant ancestor of Yonah and Gideon. Gideon's love of scenery is an aspect of his character he shares with Alter, a former program who gained free will and traveled the Metaverse to see all kinds of scenery.
Isabelle is one of the few characters with an official romanization via the Arcaea collaboration. However, イゼヴェル is likely a variation on イゼベル, the Japanese spelling of Jezebel—if she hadn't already appeared in Arcaea, it would likely be spelled "Jezevel" here. Jezebel is the biblical wife of Ahab, known for instituting the worship of Baal. Her surname, Yagrush, is one of two weapons wielded by Baal. Its counterpart Ayamur is the likely origin of Joachim's surname.
Esther, another character with the same surname, had her name romanized as "Jagrush" on official Arma Bianca merch.
Like Mene and her predecessors, Lena is the surface counterpart of digital Metaverse character Artemis Lena. Artemis Lena's voice actor Maaya Uchida was recently also cast as Lena Ishmael in Chunithm's collaboration with Re:Stage Prism Step, which also provided an official romanization.
Ishmael is the narrator of Moby-Dick, and a contrasting figure to Captain Ahab, one of Ahav's namesakes. Where Ahab is obsessive and vengeful, Ishmael is curious and open-minded, not unlike Ahav and Lena.
Ishmael also comes from Genesis, from the first son of Abraham. After being unable to conceive a child with his wife for a long time, Abraham finally had a child with her handmaiden Hagar—and learned he would be blessed with numerous descendants to come, perhaps aligning with Lena's role as the first of many in the rebirth of humanity.
The romanization for his name was provided on official merchandising by Arma Bianca (March 2024).
The source of his first name is likely a reference to Lot from the Book of Genesis. He was never given a first name as a test subject, implying he chose his own name "Lotto" later in life. He reminisces and claims one of the only things he had as a child was his specimen name, SS-012, so he adopted it as a surname.
The number 12 can be a reference to many things, but it's most likely an homage to Jesus Christ's 12 apostles from the New Testament—especially given it's described Lotto had several clone siblings in the lab he grew up in.
It could also be a tie to the 12th major arcana of the tarot, The Hanged Man. There are visual similarities between the usual depictions of Lotto and The Hanged Man, with one leg crossed, and the traditional expression suggesting that he is hanged of his own accord; alongside the card representing self-sacrifice rather than punishment. A halo also appears behind his head, signifying enlightenment and higher knowledge (a parallel to his knowledge of Bathsheba's true desire).
Odin from Norse mythology can also be linked to The Hanged Man. Odin plucked his eye in exchange for immense wisdom and the mastery of magic from Mimir's well, and was also hung from the Yggdrasil tree of life for 9 days and nights-- this being a common reference for depictions of The Hanged Man.
The romanization for his name was provided on official merchandising by Arma Bianca (March 2024).
The source of his first name is likely a reference to Cainan (קֵינָן) from the Book of Genesis' Greek translation/Book of Jubilees/genealogy of Jesus given in Luke 3:36 in the New Testament. His name is derived from root words in Hebrew meaning "possession" (קָנָה), "to make a nest" (קָנַן), and "blacksmith".
In general, the Biblical Cainan carries overt references to him and his role in the Bathsheba War Arc story-line.
The appearance of Cainan in Biblical accounts being inconsistent (such as not appearing in the Masoretic Text, the most common Hebrew version of Genesis), while at the same time being considered an important person in some accounts, is thematically appropriate for Thero's erosion of "Cainan" as himself. His lasting legacy is preserving the science of astrology and astronomy by finding records carved on rocks by former generations-- and being considered as a God to his children for his work, who continued to worship him after his death. In general, Cainan's appearances in The Bible are frequently omitted, with some historians and linguists questioning the motives as to why. Some accounts say his existence might be fabricated.
Sefer haYashar, known in English as The Book of Jasher, contains a passage (ch. 2, ln. 11-14) that closely mirrors the thematic elements of Cainan and his general role in the story. "[12] And Cainan knew by his wisdom that God would destroy the sons of men for having sinned upon earth, and that the Lord would in the latter days bring upon them the waters of the flood... [14] And Cainan reigned over the whole earth, and he turned some of the sons of men to the service of God." The authenticity of The Book of Jasher to include with the rest of The Bible is historically debated, with some considering it a non-canonical "lost book".
Mene is another name for Selene, goddess of the moon in Greek mythology. A number of characters from the digital side of the Metaverse are also named after various moon goddesses: Hecate, Artemis, Selene herself, Diana, and Luna. Those last two, sisters Diana Primera and Luna Nova, are Mene's direct predecessors: they were reborn as bots Brillante E/S Primera and Grave Nova, whose mind fused with each other in their battle to the death. Mene's story implies she was eventually reborn from them, and her surname Tercera, Spanish for "third," marks her as the third generation.
Rhea was the mother goddess of the five Olympian gods, as well as Hades. She is associated with fruitfulness and prosperity. This felt fitting with her role in the story and her association with Olympias.
Similarly, the golden laurel wreath on her head is also a symbol from Greek mythology.
Although the ・エ・in her name may imply it to be multipart or a nobility particle, it was not immediately clear which particle it may be. Instead, it was chosen to merge it with the rest of the name to make "Ephrata", derived from Ephrath—the former name of Bethlehem.
It is not uncommon for some multipart names to have developed a single word spelling over time without distinction between the syllables in English, so this was what was done here.
The "th" sound does not exist in Japanese, and "s" and "z" are often used in place of this.
"Sero/Serro" and "Cero/Cerro" were also considered. Upon the choice to work on translations, "Thero" was already commonly in use in the fandom and generally accepted in both EN and JP spaces. The origin of this spelling is unclear.
As such, the choice was made to continue to use "Thero." The same decision was not made for his last name. Via community vote, it was decided to change “Darwees” to "Dawid", the Hebrew pronunciation of "David" from the Hebrew Bible and Old Testament—a king of ancient Israel. This keeps in line with the Biblical naming conventions of the Bathsheba War Arc.
Yonah shares her name with the prophet Jonah, perhaps best known for getting swallowed by a large sea creature often depicted as a whale. Her name is spelled with a Y here both because "Jonah" scans as masculine, as well as for clarity of pronunciation. The tale of Jonah is referenced in Moby-Dick, the source of several other namesakes in the moderate arc.
"Reise" is a German word meaning "journey," and comes from OG Metaverse character Pendulum Reise (default name Pendulum Alter). She is implied to be a distant ancestor of Yonah and Gideon.

Squad captains under Sargon’s command. They are mentioned briefly in Sargon and Nadine’s plotline, but they are otherwise minor characters.
The leader of the "Awakened Ones" faction of Paragons, until Bashian takes his place. He first appears as a disguised security guard, sensing the abnormality in Bashian's behavior, and proceeds to recruit him. He is only ever depicted in Bashian's story.
A young Paragon guard who survived the battle of Ionia. With no one left to protect, he stayed until encountering Mene, and piloted their ship on her search for Lena. Briefly mentioned in Mithra's story, but otherwise only appears in Mene's. Nahum is the name of a minor biblical prophet who chronicled the fall of Assyria, and the namesake of the Book of Nahum.
The ruler of Ephes during the moderate faction arc, as well as Miriam's foster father. He appears throughout Gideon's story and briefly in Isabelle's. In the Book of Genesis, Seth is the name of the third son of Adam and Eve.
