Birthdate: June 11 Age: Mid-Late Adolescence ~ 16 Unknown (Actual Age) Gender: Female Height: 160 cm Eyes : Grey Hair: White Blood Type: AB Echo is a servant to Vincent Nightray. She seemed like an empty doll to most people, until she met Oz. Oz treated Echo as a person rather than just an empty doll, which made Echo reassess her priorities and expand on her own identity. Though Echo's loyalty was still absolute, she was suddenly able to make her own decisions based on what she believed was right, such as saving the antidote Sharon Rainsworth needed after Vincent had poisoned them both and attempted to destroy it, spending time with Oz during the St. Bridget's Day Festival and defying Vincent by revealing to Gilbert Nightray and Elliot Nightray that Xerxes Break had been fighting against Fang and Lily alone during Isla Yura's Feast. The more that Oz treated her as a person, the deeper the connection between him and Echo seemed to get. As a result, it seemed as though Echo may have developed romantic feelings toward Oz, which flourished more and more as the series progressed. In the end however, such potential went unnoticed. In battle, Echo's preferred weapon was twin blue-bladed short swords, which she'd kept in the sleeves of her dress at all time in case she ever needed to use them. Curiously enough, Echo also drew a projection of her short swords within Noise's subconscious while fighting Duldee. Additionally, while Noise appeared to be right-handed, Echo herself appeared to be ambidextrous, wielding both short swords equally skillfully with both hands. (Source: Pandora Hearts Wikia)
