『Ray』

Ray(レイ) is a Siren Xenos.

Ray has golden feathers and blue eyes. She is described to be just as beautiful as Wiene. Ray's feathers have blue tips and she wears clothing similar to an Amazoness.

Ray is warm and friendly. As one of the three leaders of the Xenos, she cares a great deal for the well-being of her kind and will go to great lengths to protect them. When Ray first encountered Bell and Welf, and briefly thinking that they were part of the hunters kidnapping the Xenos, she exuded an incredible bloodlust that was similar to a monster's instinctual urge to kill.

Like most of the Xenos, Ray holds a strong desire to live on the surface with people. She wishes to fly in the sunlight and to be held by someone she loves. When the news of the death of Ranye's group, along with the capture of Wiene and Fear, spread amongst the Xenos, she was one of the few that didn't immediately succumb to rage.

After meeting Bell and Welf and realizing they were not the Xenos hunters, Ray noticed that they were different from other adventurers, and began to hope a little that things could change. When the Hestia Familia visited their Hidden Village, she was very friendly to them and helped to alleviate their mood with her singing. During the Xenos invasion of the eighteenth floor, Ray spotted Bell but had little hope for him supporting the Xenos. However, upon hearing that Bell rescued one of the Xenos, she was filled with joy, and agreed with Lyd to go support him. Due to Bell continuing to assist the Xenos, even when doing so has brought him nothing but trouble, Ray has developed feelings for him.

Ray sometimes talks in a smattering way. She is also known for her beautiful singing voice, which caused her to become a rumor among some adventurers.
