Mu of Aries

Mu has fine, stylized features. However, they accentuate the nobility, tranquility, and elegance of this high-ranking Saint. His most prominent characteristic, typical of his race, is that he completely lacks eyebrows and has two points on his forehead that evoke the Shinto priests and women of the Heian era.
long, straight hair of a faint lilac to create an almost complementary contrast to the sea of ​​yellow tones used when he wears his Golden Cloth. As a "craftsman", as shown at the beginning of the story, we can notice that Mu wears bandages on each of his arms. Like all Cloth smiths and restorers, we have seen that the Jamirenses require shedding blood to revive or heal damaged Cloths, which would lead us to conclude that beneath them he must have a large number of scars due to his ancient trade. He wears a kind of brown toga around his shoulders that goes down and is tight at the waist, his clothes are yellow and his pants are dark green, his hair is often shown half-up on occasion.
As a final point, their attire evokes the traditional garments of Tibetan monks, but with Greek elements to create a mix of concepts.

Mu is the calmest and most peaceful of the Gold Saints. Despite everything, he is one of the most powerful. He only resorts to violence in extreme situations. Words are usually his weapon in most situations. Despite his youthful appearance, Mu displays a maturity and wisdom similar to that of the great sages.
This has earned him some enemies, like Deathmask of Cancer, but the most important thing is his loyalty and sense of justice. From the very beginning, he understands Saga's betrayal and decides to disappear until the right moment to start a revolt.
Mu has vast knowledge of the ancient art of restoring the Cloths of the Athenian Saints. He typically displays coldness and aloofness toward those who manage to reach his Jamirian tower, where he resides, as he must determine whether the traveling saint has just intentions in order to repair his Cloth.

Mu during his childhood was trained by Shion, the Pope of the Sanctuary because they were from the same homeland, Jamir, and at the age of 7 Mu becomes a Gold Saint. He also takes the blacksmithing knowledge of the Cloths from his master. This is how he is seen wearing his armor at such a young age like other children as the guard of Gold Saints (the oldest being Aioros of Sagittarius and Saga of Gemini) protects their goddess Athena.
