If the ears haven’t given it away, Multi is a robot – a maid robot, specifically, from Kurusugawa Electronics. She is a prototype, and arrives at Akari and Hiroyuki’s school for a two-week stay for final testing.  Multi is a bit clumsy but has a big heart, and is endlessly cheerful and considerate. She has a simple, childlike personality, and loves to clean because it makes others happy. As a maid, she can’t really compare to Serio; but as a “human being,� Multi is an unqualified success.  (Source: RightStuf)

Heavenly Solitude Star, Behemoth Violate (天夿˜Ÿãƒ™ãƒ’ーモスã�®ãƒ�イオレート, Tenkosei BehÄ«mosu no BaiorÄ“to?) is the "shadow" that Pandora put inside Alone's shadow to guard him. This Specter has the ability to blend completely into darkness, as she presents herself gushing out from her master's shadow and challenging Taurus Aldebaran, proving she is able to fight equally at Taurus' strength. She is also able to see through the shadows of others as seen later in the storyline, when she is depicted kneeling before Garuda Aiacos, as her right arm. Here she showed to be quite merciless, as she remained indifferent while splattered with blood and viscera when Aiacos slaughtered a nearby rebel Skeleton and a damned soul. Soon after, she was sent flying by Aiacos' Garuda Flap, withstanding its force and using it as a means to assault the Saints, freezing most of them with her mere presence, where she presented her first technique the Brutal Real (ブルータルリアル, BurÅ«taru Riaru?), a titanic stomp which destroys completely the ground below Violate. She was stopped by Leo Regulus, whom she engaged in battle. Violate's apparent physical power was confirmed when she lifted bare-handed the whole ship that the Saints were repairing. Violate manages to crush the Leo Gold Cloth's fist, and paralyzes the Gold Saint embracing his body with a huge shadow, a technique called Shadow Sewing (å½±ã�¬ã�„, Kagenui?). When Regulus manages to see through her ability, it is explained that she merges the dead from the 8th prison of Hell into the shadow so they can grab the enemy to stop their movement. She is killed by Leo Regulus' Lightning Plasma after he used his superior Cosmo to make Violate lose her influence over the dead. She reappeared some time later trying to attack Aiacos, although she stopped her blow before even hitting him; later it was revealed that it was Hades who controlled the dead body of Violate. On a side note, Behemoth Violate is the only female Specter to date.
Taurus Aldebaran is the Taurus Gold Saint in Lost Canvas. His name Aldebaran was given to the Taurus Gold Saints because it is the brightest star in the Taurus constellation while his real name is Hasgard. He is noble and a great master who apreciates his friends and students and always smiles. He is master of Teneo, Salo and Celintha to whom he once saved their life and the three chose him as their teacher. Aldebaran is said to be the Gold Saint with the fastest attack. His skill with the Iai Position allows him to maintain his arms crossed during the attack. This also allows him to perform the Great Horn, a fast technique in which he creates a big blast with his palms. His most powerful attack is Titan's Nova, a more powerful version of the Great Horn with only one arm that Aldebaran normally uses on the ground to destroy all the area. The Iai Position is broken when Aldebaran performs it. Hargard's wounds from his fight against Kagaho are torn open again during a fight, but he was able to kill Wimber after discovering that they wanted to kill Tenma. Then his heart is stopped by Cube's Death Messenger. In that moment, he has a dream of Sisyphus telling him to win, reminding him how much it hurt Athena when one of her Saints died. Then, Aldebaran performs Titan's Nova, despite his stilled heart, and kills Cube. His dead body is then attacked by a Frog Zelos but he is stopped and killed by Bennu Kagaho. (Source: Wikipedia)

Sagittarius Sisyphus (射手座ã�®ã‚·ã‚¸ãƒ•ォス Sajitariasu no Shijifosu?) is the person who took Sasha to the Sanctuary and had laid his a great hope on her. During his known missions, he looked for information about Hypnos and Thanatos, finding about the four Dream Gods. During the invasion of Hades to the Sanctuary, he attacks Hades with a Gold Arrow but Hades reverts it easily to his heart and he ends up in a comatose state. His Cosmo is then sealed by Hypnos and Thanatos, and his soul is trapped in the Dream World by the Dream Gods. He later appears in the final dream of Taurus Aldebaran, reminding him how much it hurts Athena when one of her Saints dies. Sisyphus is no longer in a comatose state, having been rescued by Sasha during the fight between Oneiros and El Cid/Tenma. This enables him to assist his fellow Saints against the dream god, shooting his golden arrow from the Pope's temple in the Sanctuary, which is intercepted in midair and cut in four by El Cid, and then pierces the four weakspots of Oneiros, thus rendering him all but vulnerable. He is entrusted by Hakurei to lead the forces of Athena during the absence of the Pope. On a side note, when Sasha rescues him inside the dream world, Sysiphus appears briefly as a Spectre, clothed with a dark version of his Gold Cloth and shedding tears of blood. To date this is the first time since the Hades arc of the original manga that a Gold Saint (different from those depicted by Kurumada) becomes a Spectre. He later appear in Jamir, to lead Athena's army into the Lost Canvas, by using the boat of hope. To defend the boat from the attack of Aiacos, Sisyphus uses arrows made of cosmo, shooting them with his bow and his direct attack Cheiron's Light Impulse (ケイãƒãƒ³ã‚ºãƒ©ã‚¤ãƒˆã‚¤ãƒ³ãƒ‘ルス Keironzu Raito Inparusu?) a powerful blast of ray of light, that provokes a massive whirlwind, extinguishing all the fire that covered Aiacos' and Athena's ship. He was able to reach the eighth sense after blinding himself. Because of the massive cosmos he reached Sisyphus could defeat Garuda Aiacos.
