Hikari (Fatalis)

Hikari (Fatalis) is a Partner in Arcaea and a story variant of Hikari. She is unlocked upon completing Testify in Axiom of the End and reading through story F-6, which requires the Final Verdict pack. 
==Character==
===Name ===
Main article: Hikari § Name
"Fatalis" is a Latin word meaning "fated/destined" or "fatal/deadly".
===Appearance===
Along with a single red butterfly near her hand, Hikari now wears two white hairclips roughly resembling her Fracture variant's contraptions and a pink-colored bow clipped at her bangs. Her hands sports a pair of long white gloves. Her hair is now much longer and faintly pink, being knee length and curled in a spiral pattern. Her eyes, previously brown and glinted, are now pink and dulled-out, with an iris pattern resembling a blooming rose. Her default expression changes from a warm smile to an emotionless, blank stare.
Her clothing consists of two-layered garments. The top layer is a white smock dress with an oversized sleeve similar in design to Tairitsu (Tempest), the ends of the sleeves are flared with a gold trim, it is buttoned with two pink colored bows close to her chest, with two more of the same bows on the sides of the dress. Attached to her neck is a white pinned collar with a gold outer rim. To her right is a pink rose with a segment that seems to drift around the right and disintegrate. The lower layer is a double tiered white thigh-length skirt with a similar frilled mock turtleneck as her original design, but with a more dense pattern. She wears a pair of double tiered white thigh-high boots with a round outer trim and a light red pointed inner trim. The lower part of the boots have various small pins attached, including a pink rose with a gold wing that is attached to both sides.
Various large pointed contraptions colored in white with a gold outer rim similar to her Fracture variant, float at her waist level. Though these differ in construction as they now resemble either push daggers or scissor blades.
===Personality===
Hikari retains her defining traits of impulsiveness and naïvete, although they now make her more ruthless and pragmatic than she is before, only putting her own continued survival into consideration and nothing else.
==Story==
Main article: Hikari § Story
Hikari is depicted in her Fatalis form in illustrations from the Final Verdict and Silent Answer Main Stories.
==Gameplay==
===Stats by level===
===Skill ===
Hikari (Fatalis) uses the unique Fatalis Gauge. This behaves like the default HARD Recollection Gauge, but with a black "fatal" threshold that slowly rises from the bottom of the bar as the song progresses.
Letting the Rate fall below this threshold immediately sets the Rate to 0 and results in a Track Lost.
The fatal threshold rises slightly with every PURE note, up to a maximum of 70% depending on the player's performance.
The rate at which it rises will differ for each chart.
The exact threshold is given by
\text{Fatal Threshold} = \left( \frac{\text{PURE Notes so far}}{\text{Total Notes}} \right)^2 \cdot 70 \,.
The threshold will therefore rise faster as the chart progresses.
Note that like the standard HARD Gauge, the Fatalis Gauge will still reduce the Rate loss for LOST notes when Rate is under 40. This reduced Rate loss zone does not climb with the fatal threshold, however, and all LOST notes will therefore incur the full -9 Rate loss after the fatal threshold reaches 40, even if the current Rate is less than 40 above the threshold.
===Other effects===
Using a sealed Hikari (Fatalis) to play Testify will re-trigger the visual effects that occur when first playing it in Axiom of the End. Using her to play Arcahv when unsealed will also re-trigger its visual effects.
When using her to play Arcahv, the Rate can fall below the fatal threshold and into negative values without triggering a Track Lost.
===Notes===
At Level 20 and with maximum stat bonuses, Hikari (Fatalis) has the highest STEP stat out of all partners by a wide margin.
When accounting for her doubled stamina cost in World Mode however, she is slightly outperformed by a maxed out Tairitsu (Tempest).
Since her maximum STEP is slightly less than double that of Tairitsu, she will progress fewer steps after one song play than Tairitsu will after two song plays.
==Trivia==
*On iOS, upon unlocking Hikari (Fatalis) the Arcaea icon will change to her face from Testify rather than Tairitsu's face from Lost Desire.
*Hikari (Fatalis), along with Hikari (Fracture) and Insight, is one of the only partners with an unknown (???) type.
**She is later on revealed to be a 'new' type of partner called "CREATOR" after reading the story A Perfect Wish. 
*This partner's STEP and OVER stats used to be half the value (V4.0.0) of its current stats, and were "buffed" with the release of the Silent Answer (v4.0.255) update.
