== Character ==
=== Name ===
Main Article: Nami § Name
=== Appearance ===
Her appearance bears similar attributes to her normal variant, in a galaxy-like theme replacing the white of her clothes and having constellation patterns. Her outfit is more frilly and the sash has a large red bow with golden stripes, the pattern also seen on the sash. The accessories adorning her buns have been replaced with a golden four-pointed star ornament with a red tied ribbon behind it, and another ribbon in black with red stripes.
She also now holds a blue traditional Japanese parasol with the interior being white and the blue swirled like it resembles the moon; a blue four-pointed star is also seen at the top of the white section.
== Story ==
Nami (Twilight) is the main character of the Astral Sea Short Story (which can be read without unlocking her, and only requires her song To the Milky Way).
==Gameplay==
===Stats by level===
===Skill===
Nami (Twilight) uses a modified version of the EASY Recollection Gauge that incurs no penalties for LOST notes, but at the cost of lower Rate gains for FAR and PURE notes.
Based on current datahttps://wikiwiki.jp/arcaea/パートナー/期間限定#namiy, the Recollection Factor (RF, i.e. the Rate gain for a PURE note) is instead given by
\text{RF} = \frac{70}{N-73} \,,
where N is the total note count of the chart.
The sole exception is when playing dropdead PST, for which the default formula for RF is used.
The Recollection Rate per note (including for dropdead PST) is given by:
*PURE: + RF
*FAR: + 0.5RF
*LOST: ± 0
For charts with greater than 183 notes (i.e. all charts except dropdead PST and the Tutorials), Nami (Twilight) gains less Rate per PURE/FAR note than partners with a default EASY Gauge.
Her skill will not trigger the Beyond Challenge in World Mode's Lost Chapter: Beyond, meaning all plays will result in Track Lost, with penalties to Performance, and no Performance bonuses for maps that have a hidden bonus (e.g. L-6, L-14).
===Notes===
Nami (Twilight) has high STEP compared to other Support type partners (and is the highest at Lv 20, as of v4.7).
Her skill, however, makes clearing songs more difficult in practice than default EASY Gauge partners. For charts with more than 741 notes (i.e. most FTR and BYD charts), her Rate gain per PURE/FAR note is less than half the gain for default EASY Gauge partners. Clearing a chart (reaching 70 Rate) with N total notes also requires at least N−73 PURE notes, meaning a maximum of 73 LOST notes are allowed (or fewer if any FARs are hit), which becomes especially punishing for denser charts.
Interestingly, since her Rate gain for LOST/FAR/PURE notes follows the same 0/0.5/1 ratio as the score gain (ignoring +1 bonuses for shiny PUREs), Nami (Twilight) is one of the only partners (besides DORO*C) for whom the current Recollection Rate correlates directly with the current score (until it reaches 100 at least).
One consequence is that the score required for Track Complete can be calculated exactly. For a chart with N notes, this minimum score is given by
\text{Minimum Score} = \frac{N-73}{N} \times 10\,000\,000 \,,
which makes her Track Complete requirement even higher than DORO*C's for charts with more than 1460 notes.
==Trivia==
*Like her base version, Nami (Twilight)'s skill and her World Mode map Fragment rewards reference the number 73, which is a goroawase for "Nami".
