Sion Eltnam Atlasia (シオン・エルトナム・アトラシア, Shion Erutonamu Atorashia?) is the main heroine of the story mode of Melty Blood and Melty Blood Re-ACT.



Originally named Sion Eltnam Sokaris (シオン・エルトナム・ソカリス, Shion Erutonamu Sokarisu?), Sion is an alchemist of Atlas located in Egypt, one of the three main branches of the Mage's Association. She is a genius scientist, given a position equal to the representative of Atlas at an extremely young age. This event gave her the name of Atlasia, allowed to be used only by those who were the head of the Atlas. She is presently being chased both by the Church organization and Mage's Association. This is because in the earlier period she assisted the Church on an assignment to demolish a vampire, but it was unsuccessful and everyone got slaughtered with the exception of her. This vampire, Night of Wallachia, was the one who made her into one of his kind. She never returned to the Mage's Association from that day on and her pursuit had began. The effect wasn't as physically powerful, surprisingly she regained control of her body after the vicious attack. Now she feels a constant thirst for blood, and is searching for a cure before she becomes a vampire. She enters Shiki Tohno's town during her search for Arcueid Brunestud, hoping that she may know a cure for vampirism, to turn her back into a human once more. She is also seeking out the vampire Wallachia to take revenge, who turned her into a vampire.


Sion is frequently composed and calculating, always determined for perfection. She is, in fact, moderately emotional and enormously easy to set off. She is a self-satisfied character, but whenever Shiki makes a remarkable statement, she gets displeased. Although she had lived most of her life in isolation, she gained her first true friend in Shiki.


Sion has long, bright purple hair kept in a long braid, white skin and purple eyes. Her regular outfit consists of a white skirt, purple shoes and stockings, and a white blouse with a purple overshirt and cap; the last two are emblazoned with the symbol of Atlas. Sion wears a mustard yellow scarf tied in a manner reminiscent of a cravat, and adorns each of her wrists with a toroidal, yellow bracelet.

While in her vampire form, her skin is pale and her eye color changes to red. The parts of her clothes that would normally be purple are instead brown, and over her body some lines, possibly veins or arteries, become visible.


Melty BloodEdit

  • Vampire Sion's ending

Sion is the heroine of Melty Blood, the game in which she first appears. She appeared in Misaki Town and met Tohno Shiki in Shinre Skyscraper when he was investigating the case of the return of the vampire serial killer in town. After a fight, they both agreed to help each other. And as the Night of Wallachia appeared within the city of Misaki Town it was able to manifest the fear present in several of the main characters’ hearts, creating entities such as an evil Arcueid who had succumbed to her bloodlust, a form of the bloodthirsty assassin side of Shiki, and even the memory of Nrvnqsr Chaos. He even managed to make her succumb to her vampiric impulses for the first time, and made her fight against Shiki. Wallachia was eventually destroyed when Arcueid used her Marble Phantasm to prematurely summon the Crimson Moon, stripping Wallachia of his power, after which he was killed by Shiki and Sion. She later returned to Atlas and persuaded the commision boards, as they denounced her for leaving Atlas, by presenting them Zepias's TATARI System, the destruction caused by Crimson Moon's return and also the concept for the self-contained computing unit named, the Osiris Sand System. In the end her name Eltnam, which she hates, and her Atlasia crown are the ones who did the favour for her. She gave away the intellectual property rights, for all of them, to the commission boards, yet her body still remembers what happens to her even if she tries to forget the memories. The information from Ries, which she stole from Wallachia, are still occupying two of her thought portions and thanks to it, her abilities have fallen. Yet, she is glad that the machine known as Sion Eltnam Atlasia is destroyed and that she is reborn as her current self. But it is still the fact that her current self is an alchemist who is at the same time a half-vampire with weak vampiric impulses. She still retains her vampire sense of smell even in her human form.

Carnival PhantasmEdit

Sion has a minor role in Carnival Phantasm. Together with Satsuki and Riesbyfe, they share a segment called "The Back Alley Alliance" when Riesbyfe ignores Satsuki and often Sion has to stop them by saying the phrase "All according to my calculations". It should be noted that Sion often says that everything was according to her calculations, even about the smallest things. She even pretends she knows about things she really does not know at all.

Other appearancesEdit

Sion appears as a playable character in the game UNDER NIGHT IN-BIRTH under the name Eltnam (エルトナム, romanized as Eltnum?). Her inclusion came about as French Bread was beginning work on a tentative Melty Blood HD, but lacked a way to continue the story because Nasu was too busy with Mahou Tsukai no Yoru. The project is currently postponed, so while working on UNDER NIGHT IN-BIRTH, they had enough time after the early stage of development to add one more character. They didn't have enough time to fully create a new character, so they used a modified test character from "Melty Blood HD" with TYPE-MOON's permission.[1]


Sion refined a special ability during her studies at the Atlas Institute: she can essentially "overclock" her brain, allowing her to forecast future events through mathematical calculation. She can also "split her brain" up to seven partitions, allowing her to run it in a parallel manner by separating her thought process, an ability dubbed "Memory Partition". She also, as the successor of TATARI, has the ability Terror News (テラーニュース, Terā Nyū?), which utilizes physical Malignant Information (悪性情報, Akusei Jōhō?) actualized through prana. In her TATARI form, she can also use Etherlite in combination with her ability Replicant Conductor ( レプリカントコンダクター, Repurikanto Kondakutā?) to create a phantom-like copy of an individual that is able to reproduce his or her abilities to an extent.

She possesses Etherlite (エーテライト, Ēteraito?), a portmanteau of Ether Lite, which is a monofilament with a maximum range of 5km, created by the Eltnam family. Etherlite is a Mystic Code, which has the form of a bracelet and she possesses two of them. Though she uses it to provide mind reading capabilities to its owner, it was originally a substitute nevous system developed for medical purposes which also has an anesthetic effect. After making contact with the skin of the target, it will connect itself to his mental nerves and establish a mental link between him and the user, giving its her family the nickname of “spiritual hackers”. Its use however, carries the risk of “reproduction of knowledge”, which would cause memories and feelings to be shared. Etherlite is condemned even in Atlas for its potential of “stealing the lives of others”. In addition, if attached in the right way, this cord allows her to control other people's bodies and to release the limiter of the nerves allowing a temporary increase in physical ability but the feedback on the body is large so it can only be used for a few minutes. Etherlite can also be used as a whip that can slice through people or restrain them. Sion also possesses Barrel Replica, a Mystic Code that is a replica of the Black Barrel. It is a Conceptual Weapon of "natural life" that puts outs a toxin in proportion to that life form's natural life span. Sion's Arc Drive uses this Barrel Replica, but it seems that its normal power hasn't been utilized. Barrel Replica Obelisk, Sion's Last Arc, emits power laterally, but in order to prevent herself from being blown off by the recoil, she anchors her body with Etherlite. Though it is incapable of wiping out Night of Wallachia, it can hamper the program by many years.
