Southern Cross Kazuma (南十字座（サザンクロス）の一摩, Sazan Kurosu no Kazuma) is a powerful Silver Saint and Sōma's father, who was killed in the past in front of him. His memory constantly haunts Sōma. Kazuma can use the element of Fire.
Kazuma was a man much beloved by all the people of his homeland. The same way his son Lionet Sōma , he always had an air of mischievous and playful, but that did not stop him from being a serious Saint and honored. Days before his death, Kazuma teaches his son the secret of all his strength as Saint.
Kazuma was respected by other saints, and feared by the forces of Mars, as a leader of a future revolution, along with it, other Saints were plotting a counterattack against the forces of mars, and even knew of the conspiracy that occurred in Palaestra, however Kazuma rather wait for the right moment to attack.
Kazuma, went to meet Hornet Sonia , who stalked the Saint indgnou with the fact mars send a child to attack him, Kazuma did not fight seriously with Sonia, showing it to be much higher, a moment of benevolence orders Sonia to return home and give back to Mars letting his guard down. At this moment a low blow, Sonia kills Kazuma, who was killed before the eyes of his son, Soma, which can do nothing but to flee, vowing revenge.
As said by Soma in the early chapters, Kazuma inherited after his death the fame of being a weak Saint, making his reputation and Soma fall too. But that never stopped Soma is mirrored in him as an example of strength, determination and heart.
In memory of Orion Eden, it is shown that Kazuma was a very powerful opponent before Hornet Sonia , who left badly wounded after combat. It is also shown that, for some mysterious reason, Hornet Sonia kept with him the Clostone of Kazuma.
Southern Cross Kazuma's Cloth of Southern Cross is silver with black and red accents. It has two shoulder pads, the chest protector in its body, within is a small red cross. A similar silver cross adorns the armor's black and silver helmet.
Crux // is the smallest of the 88 modern constellations, but is one of the most distinctive. Its name is Latin for cross, and it is dominated by a cross-shaped asterism that is commonly known as the Southern Cross.
Crux is easily visible from the southern hemisphere at practically any time of year. It is also visible near the horizon from tropical latitudes of the northern hemisphere for a few hours every night during the northern winter and spring. For instance, it is visible from Cancun or any other place at latitude 25° N or less at around 10 pm at the end of April.
Crux was visible to the Ancient Greeks; Ptolemy regarded it as part of the constellation Centaurus. It was entirely visible as far north as Britain in the fourth millennium BC. However, the precession of the equinoxes gradually lowered its stars below the European horizon, and they were eventually forgotten by the inhabitants of northern latitudes. By AD 400, most of the constellation never rose above the horizon for Athenians.
The 15th-century Venetian navigator Alvise Cadamosto made note of what was probably the Southern Cross on exiting the Gambia River in 1455, calling it the carro dell'ostro ("southern chariot"). However, Cadamosto's constellation had too many stars and was tilted incorrectly. Historians generally credit João Faras - astronomer and physician of King Manuel I of Portugal who accompanied Pedro Álvares Cabral in the discovery of Brazil in 1500 - for being the first European to depict it correctly. Faras sketched and described the constellation (calling it "Las Guardas") in a letter written on the beaches of Brazil on May 1, 1500, to the Portuguese monarch. Émerie Mollineux has also been cited as the first uranographer to distinguish Crux; his illustration dates to 1592. Later adopters of the constellation included Jakob Bartsch in 1624 and Augustin Royer in 1679. Royer is sometimes wrongly cited as initially distinguishing Crux. Explorer Amerigo Vespucci depicted Crux as an almond, called "Mandorla".
Crux was first shown as a separate constellation on the celestial globes of Petrus Plancius and Jodocus Hondius in 1598 and 1600. Its stars were first catalogued separately from Centaurus by Frederick de Houtman in 1603.
