Joshua is Ray's brother who is outgoing, enthusiastic, and friendly. Although he loves Ray deeply, their personalities are quite different. According to Joshua, Ray's behavior changed after the death of his wife Yoshimo at the hands of the Claw Man. While Joshua also cared for Yoshimo, he hopes that Ray will come to terms with her passing and return home rather than seeking revenge against her killer. Joshua possesses exceptional technical abilities, including repairing everyday items, identifying armor vulnerabilities, and setting up timed explosives.
