Es is one of the main characters in XBlaze – Code: Embryo and a playable character in the console version of Blazblue: Central Fiction. Es is a member of the Mitsurugi Agency, tasked with hunting down the Drive-Infected Patient's so they could be treated for their unfortunately terminal condition. Emotionless, steady, and objective focused. 
Es is the perfect soldier, her mission always comes first. When she first met Touya Kagari, she did not care for him or any other person, being willing to hurt and even kill others that she was 'friends' with just so she could complete a mission. If Es did not understand a term, mainly because of the informality or colloquial speech, then she would forwardly ask what said term means, leading to unique, and awkward situations. For a time, she possessed no opinions due to her little interaction with people outside of the Agency, as well as this, Es possessed a habit of taking things too literally, annoying Touya as he put up with her awkward social tendencies.
Es is actually a Manifest Boundary Contact Prime Field Device, and her real name is Embryo Storage (エンブリオストレージ). Her actual age is only 5, and she was developed at the time of her sister units' and creator's death./
Es wields one of the legendary Legacy Weapons – Vow Crystal Seal Blade: Murakumo. Her skills with the blade are awe-inspiring, being able to deflect multitudes of shrapnel being launched at her by Akio Osafune. On top of this, Es is strong enough to survive a multitude of blows dealt by the physically impressive Drei. Adding to her physical abilities, Es has an abnormally fast reaction time, coupled with impressive speed; she was able to even catch up to Ripper. Even unarmed, she possessed enough strength to easily lift and carry Touya Kagari a considerable distance without fatigue. Because of her blank expressions and apparent lack of emotions, even Ripper's taunting could not provoke her, proving her to be incapable of panicking and losing the psychological advantage./
