Hikari (Zero) is a Partner in Arcaea, and a variant of Hikari. She is available through Spire of Convergence.



Main article: Hikari § Name


Her dress has changed to a much simpler design, with her red bow tie changed to a ribbon tie. Her red beret is lost, and replaced with a white cloth that surrounds her entirely.

She is now barefoot, and kneeling on the ground. Flowers surround her vicinity, with one of them growing vines and going around her right hand.


Her careless personality and obsession with happiness has led her to a path of insanity. The happiness that she experienced slowly turns dull as she slowly feels empty. She would attempt to cage herself so she didn't have to worry about anything. This caused her mind to become completely empty and she would slowly white out.

Hikari (Zero) is aptly named due to her decreasing stats over time until 0 at level 19 and 20.

  • Her maximum FRAG stat (at level 1) translates to 1.54x frag multiplier
  • Her maximum STEP stat (at level 1) translates to 1.22x step multiplier for world mode

It is worth mentioning that her level 1 stats are the same as base Hikari at level 20. This means that farming for fragments is still best left to Tairitsu or other partners with a higher FRAG stat. This is compounded by the fact that you need to level up Hikari (Zero) to level 4 to progress through the story and unlock Fracture Ray (see Ether Strike § Anomaly).

Hikari (Zero) is by no means a practical partner. However, she is integral to the story of Luminous Sky and her "Zero" skill can be used as a personal challenge for getting FR or PM. At higher levels, she is also very useful to get to Stamina tiles in world mode when you only have a few steps remaining to the tile as you need to land at exactly on the tile to get the extra Stamina for world mode.

Contrary to the type she is grouped as, she does not give a red (hard) clear. Instead, she gives a normal (purple) clear.


  • She is the first World Mode unlock Partner that is required to unlock an anomaly.
  • She is the only Partner to decrease her stats upon leveling up. She is also the first partner to be able to have 0 stats.
  • After 2.1.0, her stats from level 17 are displayed with decimals.
    • She is one of the only 2 partners to have a non-integer stat, the other being Nono Shibusawa.
