The story is divided in a way named the same way you would write a journal.
Entries
This song was the first of its kind to be added into the game, not only introducing a new unlock system, but also a new level of difficulty as the first song with a difficulty rating of 11.
Grievous Lady
In Arcaea, you have four types of notes. Tap notes, hold notes, sky notes, and these notes that force you to move your fingers around the screen.
Arcs
This partner was the first variant partner to be added to the game, at the same time as the first song with a difficulty rating of 11.
Tairitsu (Axium)
The most awaited and well-known collaborations made with Arcaea was with this rhythm game that has a more technological theme and a moving judgment line.
Cytus II
Aside from the focused story, other shorter stories that are happening around the world often act as a type of non-required quest.
Side Stories
This song leads to the boss song "Fracture Ray" and was made by one of the now deceased sound designers for the game.
Ether Strike
This incredibly complex and convoluted system has a prevalent role in unlocking some songs, but even to this day, no one fully understands how it works or why it randomly drops when missing a single note.
Potential
This partner is currently unique in the fact that there is a risk of losing something other than your pride when failing to clear a song, costing you 100 Fragments, which is the in-game currency.
Ilith
This collaboration with Arcaea added a song called "Protoflicker," despite Arcaea not having any flick notes to speak of.
Lanota
The way of unlocking the pieces of the stories is rather simple. This is a rhythm game, after all.
Playing Songs
This song is home to the greatest challenge in the entire game and is named after a storm and an Italian suffix commonly used in music.
Tempestissimo
This gauge is your way of clearing a song, and comes in many unique variants thanks to certain partners.
Recollection Rate
This partner uniquely changes the rate at which your gauge increases and decreases, and is the only partner with only one eye, as she has a flower blooming where her other eye should be.
Saya
Daily Double
This collaboration, which has been removed from Arcaea for years, was only available for 6 days and has the now-rarest Partner in the game originating from the collaboration.
Stellights (Double Points if they can guess the rare partner, Stella)
These two main characters were named after the Japanese words for light and conflict, respectively.
Hikari and Tairitsu
Daily Double
This song was the first to have any true visual changes during its first play, is used in a side story, and is also used in a meme related to bagels.
Aegleseeker (Double Points if they say Bagelseeker as their guess.)
The names of different note judgements, in the order of miss, early/far, and perfect, are the opposite of found, the opposite of close, and the opposite of corrupted.
Lost, Far, Pure
This partner was the first to horizontally mirror the location of the notes and was also the first partner to change the visuals in their awakened state. Her name is Greek for "forgetfulness."
Lethe
This collaboration with a new "steering wheel" style rhythm game was the first collaboration to come with its own story chapter.
Rotaeno
When it comes to story structures, there is often a 3-act system. Act one is named after the action most people use in creative jobs.
Creation
This song is only unlocked after passing a "point of no return," is the only song to have a difficulty rating of 12, and its title is something most people do in religion, or maybe just a court hearing.
Testify
While you can get an "All Perfect" by hitting all Pure notes, no two scores will be the same due to this function that remains hidden until you activate the setting of the same name.
Early/Late Pures
This variant of one of your starting Partners has turned away from making the game easier, and has instead made it so that the farther you go in the song, the less room you have for error. She did what she had to do to survive.
Hikari (Fatalis)
This Arcaea collaboration was with a game that would later be forgotten due to the new game of the same "washing machine" style called MaiMai.
