Heavensdoor - LeaF
Pack (Mobile): Adverse Prelude
Pack (Switch): Adverse Prelude

## Trivia

* According to a comment by LeaF, Heavensdoor was composed to evoke a feeling of hollowness or emptiness. Part of this idea was to use a very small set of sounds, and the song uses only kicks.
* Tairitsu (Grievous Lady) appears in the BYD jacket.
* The chart design credit translates to "Toaster ※ Heaven's Door".
* This song's Beyond chart was the first BYD 10+ in the game.
* This song and GOODTEK's Beyond jacket art are the only Beyond jackets to be made by completely different artists and have an entirely different appearance, excluding the April Fools songs.

Pack (Mobile): Light of Salvation
Pack (Switch): Light of Salvation

## Trivia

* Divine Light of Myriad was one of the winners of Arcaea Song Contest 2020.
* The Japanese title for this song is "光速神授説 - Divine Light of Myriad -" (*Kōsoku shinju-setsu - Divine Light of Myriad -*, lit. "theory of divine lightspeed").
	+ The title is similar to the phrase "王権神授説" (*Ouken shinju-setsu*), lit. "theory of the divine right of kings".
* Lagrange appears in the song jacket.

**Mobile:**
* When this song was added, the BPM was mislabelled as 344 BPM, causing it to temporarily exceed Galaxy Friends as the song with the highest static BPM.
	+ This was corrected in version 3.7.1.

Kanae (Midsummer)

*This partner is currently exclusive to the mobile version of Arcaea.*

## MidsummerKanae

NIGHT: HARD - Gain +5 Fragments on Track Clear. This skill changes during the day.

## Information

### Unlock

Map 0-LE Kanae Midsummer Event
(purchase Evening in Scarlet)

### Signature Song

Evening in Scarlet

**Kanae (Midsummer)** is a limited Partner in Arcaea, and a variant of Kanae.
She can be unlocked by purchasing her signature song Evening in Scarlet and playing her event map, which was first available from August 24th to September 7th, 2021.

## Gameplay

### Stats by level

*Hover your cursor over a stat to see its corresponding multiplier.*

### Skill

Kanae (Midsummer)'s skill, like Kanae's skill, changes depending on the device time:

* 6:00 AM to 7:59 PM - DAY
* 8:00 PM to 5:59 AM - NIGHT

Her DAY skill uses the EASY Recollection Gauge, and deducts 10 Fragments upon starting a song or restarting a song from pause. Fragments are not refunded for quitting mid-song. This Fragment cost also applies in World Mode.

Her NIGHT skill uses the HARD Recollection Gauge, and awards a +5 Fragment bonus for successfully clearing a song.
This bonus is given before the FRAG multiplier is applied.

## Trivia

* The Fragment cost associated with her DAY skill did not initially consume Fragments when restarting a song from the results or pause screens. This was patched out in v4.3.0, however.

Kou (Winter)

*This partner is currently exclusive to the mobile version of Arcaea.*

## WinterKou

**Kou (Winter)** is a limited Partner in Arcaea, and a variant of Kou.
She can be unlocked by purchasing her signature song Capella and playing her event map, which was first available from December 22nd, 2022 to January 5th, 2023.

## Gameplay

### Stats by level

*Hover your cursor over a stat to see its corresponding multiplier.*

### Skill

Kou (Winter)'s skill works as follows:

* If Kou (Winter) is **not the active partner** (partner can be unsealed or sealed):
	+ Once a play is complete, 25% of fragments (rounded down) obtained from that play is "shared" with Kou (Winter). The player receives the full amount as usual.
	+ Playing songs with other partners will continue to increase Kou (Winter)'s cumulative "shared" Fragment stockpile until a song is played using Kou (Winter). This stock will stop increasing at 999 Fragments.
* If Kou (Winter) **is the active partner**:
	+ After completing a song play with **unsealed** Kou (Winter), her full Fragment stockpile is awarded as a PARTNER Bonus for Fragment calculation (i.e. before the FRAG multiplier). This sets her stock back to 0.
	+ If Kou (Winter) is **sealed**, Fragments are awarded as normal. There is no change to her Fragment stockpile, and no PARTNER Fragment bonus.

Note that her "shared" Fragment count is saved locally on the device, and exiting and re-opening the game does not reset this count.

* *e.g. If 66 Fragments are obtained from one play (Level 30 Kou + SOUNDWiTCH FTR PM):*
	+ *⌊
	66
	×
	0.25
	⌋

	{\displaystyle \lfloor 66\times 0.25\rfloor }

	= **16** Fragments are "shared" with Kou (Winter).*
* *If 62 more Fragments are obtained from a second play (Level 30 Kou + Evoltex FTR PM):*
	+ *⌊
	62
	×
	0.25
	⌋

	{\displaystyle \lfloor 62\times 0.25\rfloor }

	 = **15 more** Fragments are shared with Kou (Winter).*
	+ *At this point, a total of 16 + 15 = **31** Fragments have been "shared" with Kou (Winter).*
* *If a Level 13 Kou (Winter) is then selected on the third play and an Evoltex FTR PM is achieved:*
	+ *CLEAR = 3 (FTR) + 7 = 10*
	+ *PERFORMANCE =

	⌊

	⌊

	8
	1.25

	0.2

	⌋

	×
	2.7

	⌋

	{\displaystyle \left\lfloor \left\lfloor {\frac {8}{1.25}}+0.2\right\rfloor \times 2.7\right\rfloor }

	 = 16*
	+ *PARTNER = No. of Fragments "shared" with Kou (Winter) = 31*
	+ *Total Fragments obtained from this play = 45/50 × (10 + 16 + 31) = **51** (after rounding)*

### Notes

Like the base version of Kou, Kou (Winter) is one of the most useful parters available for Fragment farming.
Simply having Kou (Winter) as an unlocked partner effectively allows one to increase total Fragment gain to (slightly under) 125% for all plays where she isn't used.

## Trivia

* Kou (Winter) is one of several Partners whose skill is affected by song plays made when she is not selected.
* As of v4.1.7, the maximum amount of fragments one can obtain with one play using Kou (Winter) is obtaining a PM on Testify BYD.
	+ This will net the player (11 + 27 + 999) × 1.0 = 1037 Fragments if Kou (Winter) is at level 20.

## Trivia

* Linear Accelerator's Future chart contains a section where groups of traces form in circles, while the chart speeds up, slows down, goes backwards and then normal speed.
	+ This is a reference to Linear Accelerator's BGA in Tone Sphere, where the camera zooms through a formation of rings.

DORO*C

*This partner is currently exclusive to the mobile version of Arcaea.*

**DORO\*C** is a limited collaboration Partner in Arcaea, added as part of the first Arcaea x HARDCORE TANO\*C collaboration.
She can be obtained by purchasing her signature song SAIKYO STRONGER and playing her event map, which was first available from January 22nd to February 1st, 2020.

## Gameplay

### Stats by level

*Hover your cursor over a stat to see its corresponding multiplier.*

### Skill

DORO\*C's skill uses a special Recollection Gauge that measures the highest possible grade at song completion based on player performance, i.e. the grade that would be achieved if all note judgements from that point on are PURE.
Rather than a numerical Rate indicator, the indicator gives the highest possible grade at that point (EX+, EX, AA, A, B, C, or D).
The Gauge is divided into six sections, one for each possible grade (with EX+/EX occupying one section).
The Gauge will not increase for PURE notes, and will decrease for FAR/LOST notes (with LOSTs causing double the decrease as FARs).

Achieving a Track Complete requires a final grade of AA or above (i.e. a minimum score of 9,500,000), or a Full Recall with any grade.
A final grade of A or lower without a Full Recall will result in a Track Lost.
Despite being a Balance type partner, DORO\*C gives a green (easy) clear upon Track Complete.

Her skill will not trigger the Beyond Challenge in World Mode's Lost Chapter: Beyond, meaning all plays will be treated as Track Lost, with penalties to Performance, and no Performance bonuses for maps that have a hidden bonus (e.g. L-6, L-14).

### Notes

DORO\*C's stats emphasise on FRAG, but all of her stats are below average even at level 20.

With the exception of Hikari (Zero), DORO\*C has the second lowest maximum stat sum out of any partner, only slightly above that of Nami, making her impractical for fragment farming or World Mode progression.

However, her unique Recollection Gauge is useful for monitoring a player's performance during a song, to an extent not possible with other partners, with the exception of Lagrange.
With her Gauge, it is possible to see during the round if a particular grade can still be obtained. However, the Gauge is not completely accurate near the thresholds, and sometimes displays the higher grade when the score is just below the requirement.

## Trivia

* DORO\*C is the mascot character of the HARDCORE TANO\*C label, and appears on the covers of their HARDCORE SYNDROME compilation series.
* She is the first partner to have a level-invariant OVER stat.

目の疲れからくる頭の痛み、

肩こりや首こりからくる頭の痛み、

首のスジのコリからくる頭痛には

ツボ圧しが有効です。

I've a headache now

As hit with a hammer

I've a headache now

Cause sight is darker

Pissed me off, suppress my riot

Shut up Damn it, Head BONK ache

頭の付け根に特にコリやすいスジがあり、

頭が痛い原因はこのコリが原因のことがよくあります。

I've a headache now

As hit with a hammer

I've a headache now

Cause sight is darker

Pissed me off, suppress my riot

Shut up Damn it, Head BONK ache

Source: Official Bandcamp

Romaji/English

Me no tsukare kara kuru atama no itami,

Katakori ya kubi kori kara kuru atama no itami,

Kubi no suji no kori kara kuru zutsuu ni wa

Tsubo oshi ga yuukou desu.

I've a headache now

As hit with a hammer

I've a headache now

Cause sight is darker

Pissed me off, suppress my riot

Shut up Damn it, Head BONK ache

Atama no tsukene ni tokuni kori yasui suji ga ari,

I've a headache now

As hit with a hammer

I've a headache now

Cause sight is darker

Pissed me off, suppress my riot

Shut up Damn it, Head BONK ache

English translation

Headaches from eye strain,

Headaches from upper back stiffness,

And headaches from neck stiffness

Can be treated effectively by targeting pressure points.

I've a headache now

As hit with a hammer

I've a headache now

Cause sight is darker

Pissed me off, suppress my riot

Shut up Damn it, Head BONK ache

Certain muscles at the base of the neck are especially prone to stiffness,

And this stiffness is often the cause of headaches.

I've a headache now

As hit with a hammer

I've a headache now

Cause sight is darker

Pissed me off, suppress my riot

Shut up Damn it, Head BONK ache

## Trivia

* Head BONK ache debuted as an entry to THE BMS OF FIGHTERS XVII -VISION THE RETRO FUTURE-. With a score of 157636, it ranked 5th place overall.
* The trace art in this song's Future chart was drawn by TaroNuke.
* According to the vocalist kei\_iwata, some lyrics were changed and re-recorded for the Arcaea version.
	+ The Arcaea edit features "Shut up, damn it" in place of "Fuck off, shit head".
	+ This edited version was also present on saaa's album, Mechanical Armageddon as an extended version of the song.

Cyanine

## Lanota Collaborationcyaninejioyi

cyanine - jioyi
Pack (Mobile): Lanota Collaboration
Pack (Switch): Lanota Collaboration

## Trivia

* Cyanine is the boss song of Chapter II of Lanota's Main Story, "Dissonance in the Farm Village".
* This is the only song in the Lanota Collaboration pack that was cut shorter for Arcaea.
* The Future chart follows Lanota's Master difficulty chart in some places, and many note movements resemble it.
	+ In particular, the intro section's circular guide lines resemble the notalium tuner that serves as Lanota's playfield.
* The note designer's name is likely an alias of Nitro. 夜 is "night," while 浪 can be read as "rou." Literally, it means "night wanderer" or "wandering in the night."
* Cyanine is the name of a family of synthetic dyes used for many fluorescent purposes, such as biomedical imaging .

Areus

*This partner is currently exclusive to the mobile version of Arcaea.*

**Areus** is a limited collaboration Partner in Arcaea, added in Chapter 2 of the Arcaea x CHUNITHM collaboration.
They can be obtained by purchasing the CHUNITHM Collaboration Chapter 2 pack and playing their event map, which was first available from January 21st to February 18th, 2021.

## Gameplay

### Stats by level

*Hover your cursor over a stat to see its corresponding multiplier.*

### Skill

Areus' skill uses a modified version of the HARD Recollection Gauge, where the Rate loss for a LOST note will increase depending on the length of the broken combo.
The Rate loss per LOST note becomes

Rate change per LOST

=

Standard Rate change per LOST

RF

⋅

Combo before LOST
4

,

{\displaystyle {\text{Rate change per LOST}}={\text{Standard Rate change per LOST}}+{\text{RF}}\cdot {\frac {\text{Combo before LOST}}{4}}\,,}

where RF is the Recollection Factor, i.e. the standard Rate gain per PURE note.
Clearing songs with Areus' skill gives a hard (red) Clear.

When using Areus in Lost Chapter: Beyond, FAR notes will incur the same Rate loss as default HARD Gauge Partners, with no additional penalty based on combo.

## Trivia

* Areus is an original playable character in CHUNITHM. They debuted in *CHUNITHM AMAZON* ep.III as part of the Metaverse character universe, with their signature song Climax.
	+ Their name in Japanese is アレウス (*Areusu*). Their full name in CHUNITHM is 憎悪の戦神 アレウス ("War God of Hatred, Areus")
	+ Their partner art in Arcaea comes directly from CHUNITHM.
	+ Areus' gender is not specified in any official CHUNITHM media. Guy however has commented that "Areus is a god, not a male human".
* Areus' name in Greek ("Αρεως") means "of Ares". Ares (Αρης) was the god of war in Ancient Greek mythology. This follows the mythological naming scheme of numerous CHUNITHM Metaverse characters.
* Like their Arcaea skill, Areus' 憎悪の咆哮 ("Roar of Hatred") skill in CHUNITHM causes immediate song fail under harsher than normal conditions that depend on combo.
* The stats of all three CHUNITHM Collaboration Chapter 2 partners are permutations of each other at all levels from Lv 1-20, being a permutation of 47/47/61 at Lv 1 and 70/70/90 at Lv 20. Areus focuses on STEP (vs Isabelle Yagrush's FRAG focus and Seele Haze's OVER focus).

* There exists controversy regarding the legitimacy of this song submission.
	+ In May 2020, AlterAle (previously separated as Alter Ale) was submitted to the CHUNITHM contest 「第三回チュウニズム楽曲公募」, and had been disqualified.
	+ As such, though not explicitly stated, lowiro issued an official apology, presumably on behalf of the composers and the team, stating that:
		- "lowiro had been notified about a song from this contest being previously released through another medium,"
		- "lowiro strives to uphold fairness in contests and apologises for the oversight,"
		- "the issue has been settled with the artist[s] in question," and
		- "no further action will be taken at the time the apology is issued."

* Illegal Paradise first appeared in BOFU2015. With 96207.5 points, it placed 39th.

Lights of Muse - Ayatsugu\_Otowa
Pack (Mobile): Muse Dash Collaboration
Pack (Switch): Muse Dash Collaboration

## Lyrics

Try as all might to succeed

You make it so hard to believe

And I'm chasing dreams I can't achieve

And each time doubt to fail

I dare myself to bail on now

I'm tangled in the sense of insecurity

I've learnt to take the rejection

to struggle with every mistake

It's the step in the right direction, they say

You gotta fight

For the right to be here!

You gotta fight

For the right to stand tall!

You better fight

For the right to get noticed!

It's a big world that we're living

Too easy to give in

So fight for your right to be,

For the right to be here

You better fight

For the right to get noticed!

It's a big world that we're living

Too easy to give in

So fight for your right to be,

For the right to be you!
