Luna

Luna is described as merciless, as stated by the trailer of the Binary Enfold release. Luna also does not feel friendly and affable to other people as well, while daring people to play her challenge, Singularity. This, however, is conflicted by her apparent platonic affection and attitude towards her twin sister, Eto, as shown in the Binary Enfold story. 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.
