Character[]

Name[]

Eto comes from French "étoile", which means "star".

Appearance[]

Eto looks similar to Luna as they are twins. Both look particularly petite compared to the rest of the partners. Eto's design features multiple stars, like her namesake, in contrast to Luna's moon motif. 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 shaped like a five-pointed star. 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.

Personality[]

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

Note that to Awaken Eto and Luna, the Shared Time DLC must be purchased to gain access to the map containing their necessary Binary Cores.

Skill[]

Eto's unawakened skill grants a +5 Fragment bonus after playing a Light side song (this does not apply to Colorless side songs). This bonus is given before the FRAG multiplier is applied.

Her Awakened skill grants a +7 step bonus in World Mode, activated if the current play lands on a new Fragment reward tile. Plays that start on a tile with an already collected Fragment reward do not award this bonus. The +7 step bonus is added after the STEP multiplier is applied.

Mobile:

Notes

Eto's unawakened skill and its +5 Fragment bonus make her a good choice for Fragment farming when playing a light song (potentially outperformed by a few partners, including a max level Pandora Nemesis (MTA-XXX) or Ayu due to her skill or an awakened Kou, since she also provides a similar bonus).
