Eto is one of the Partners in Arcaea. She is available through Outer Reaches after purchasing Binary Enfold.



Eto comes from French "étoile", which means "star". An ornament shaped like a five-pointed star can be found on her cape.


Eto looks similar to Luna as they are twins. Both look particularly petite compared to the rest of the partners. Unlike Luna, Eto has wavy blonde hair and blue eyes, as well as a star tattoo on her left cheek. Both twins have the same beret, cape, and pleated-lined shirt but with different colors and ornaments — with Eto's colors being blue, her shirt having long bell sleeves, and the ornament being star-shaped. They both also wield the same rapier weapon; this has been shown to be two halves of a pair of scissors.

Eto wears navy blue shorts on her lower half of the body. She wears different footwear on each leg, with her right leg clad in a boot up to half of her lower leg as well as a blue ribbon wrapped around the rest of her leg and tied at the back, and her left leg clad in a boot with a cuff at the top.


Eto has been officially described as "amiable".[1]

Raw stats wise, she is more focused on FRAG but is generally below average in terms of stats sum (147 compared to the baseline 160).

  • Her maximum FRAG stat translate to 1.60x fragment multiplier.
  • Her maximum STEP stat translate to 1.34x step multiplier for world mode.

While her FRAG stat is nothing to ride home about, due to it being the exact same FRAG stat as Tairitsu, her role becomes more significant as you trigger her skill. +5 Fragments bonus is applied before the multiplier, and therefore she will give more fragments than anyone else when playing a light song (except for a max level Pandora Nemesis (MTA-XXX) or an awakened Kou, since she also provides a similar bonus).

While the STEP stat is below average, as discussed in Hikari (Zero) the low STEP stat can be used for nailing the landing on a Stamina tile.
