**Saki** is a collaboration Partner in Arcaea, added in Chapter 2 of the Arcaea x O.N.G.E.K.I. collaboration.
She can be obtained via World Mode after purchasing the O.N.G.E.K.I. Collaboration Chapter 2 pack.

### Skill

Saki's **O.N.G.E.K.I.** skill is unlocked at Level 8. It functions much like Luna & Mia's skill, granting a random bonus of +1 to +4 Fragments every time she deals "Overdamage" (i.e. brings the Rate to 100, after which it resets back down to 80 Rate).

Saki's variant of the skill grants an additional Recollection Rate bonus at the end of a chart based on "accuracy", where the Rate will increase rapidly and deal multiple additional Overdamage after the final note judgement. Accuracy here is based on the fraction of notes hit with a shiny PURE judgement (i.e. not counting early/late PUREs).
The bonus Rate is given by:

# Additional Overdamage Rate Bonus

{

100

(

1
−
4
⋅
n

)

if
n
≤
20
%

25
⋅

(

1
−
n

)

if
n
>
20
%

,

{\displaystyle \text{Additional Overdamage Rate Bonus}=\begin{cases}
100 \left( 1 - 4\cdot n \right) & \text{if } n \leq 20\% \\
25 \cdot \left( 1 - n \right) & \text{if } n > 20\% \,,
\end{cases}
}

where *n* is the percentage of the total notes with judgements below **shiny** PURE.
This bonus starts at +100 for a max PURE Memory, decreases linearly to +20 for 20% notes below shiny PURE, and then decreases linearly again to +0 for no shiny PUREs. Since Rate resets to 80 after each Overdamage, this final bonus may trigger Overdamage up to 5 times, for a random bonus of up to +20 Fragments (on top of those earned during the song).

The second additional Overdamage bonus is not granted if a play ends in Track Lost.
The final total Overdamage Fragment bonus is given as a PARTNER bonus, added before the FRAG multiplier is applied.
Since Saki's FRAG is less than 50 at all levels, the final bonus will be less than that displayed by the hexagonal Overdamage counter.
Clearing songs with Saki's skill earns a purple normal clear.

## Trivia

* Saki is a character in O.N.G.E.K.I., and part of the unit 7EVENDAYS⇔HOLIDAYS.
	+ Her full name is Saki Kashiwagi (柏木 咲姫).
	+ She is the canonical older sister of Mia, and is in her 3rd year of high school.
	+ Like Setsuna and Mia, Saki is depicted in her shooter outfit.
		- Arcaea's partner art uses her shooter outfit character art from O.N.G.E.K.I.
* Saki's skill is a reference to O.N.G.E.K.I.'s Overdamage mechanic.
	+ Hitting notes in O.N.G.E.K.I. deals damage against the opponent character, whose health is represented as a percentage.
	+ Reducing their health to 0% deals Overdamage, with their health resetting to 100% afterwards. This can be triggered multiple times throughout a song.
	+ Each time Overdamage is dealt, it grants a random Jewel/Money bonus.
* Saki's variant of the skill is a reference to the スラッシュ (Slash) skill possessed by certain character cards in O.N.G.E.K.I., including some of Saki's cards.
	+ This skill deals additional damage at the end of a chart. Unlike in Arcaea, the amount of damage is fixed and depends only on the character card, not chart accuracy.
