Stealth is the second-eldest brother of the six Shadow Spirits, and the proudest one of them all. Owing to his past experiences as both a thief and a bodyguard for Time Mistress Asura, Stealth excels in espionage-based activities and is often hard to find. While he's rather quick, he's outpaced by his eldest brother, Swift; a fact the wyvern often mocks him with. While he has worked underneath Swift when he was a ruler, he wasn't present when his brother was killed. Fleeing after seeing the mess the kingdom had become, Stealth wandered around Chounen until he fell into a pitfall trap and broke his legs. Trapped and exhausted, he eventually perished as he was.
Wandering the plains as an unhappy spirit, he eventually came across Blues and a young Kage Suzaku, running away as fugitives from Blues' pursuers. Deciding to help them out, he attached to Kage, delighted when he realizes the relationship he had to his former vessel. Deciding that he would stick around after they managed to escape, he and Kage became close friends in their childhood (though Stealth took joy in tormenting Blues in simple ways, such as stealing his food from his plate when he wasn't looking, and beating him to important tasks like gathering food).
After Blues left Kage with his foster family, and the small child was subsequently stolen away by the mad cyborg-Mystic Lord, Reishiki (who won't appear in the RP), the relationship between Kage and Stealth became immensely tense. As Reishiki tormented Kage with lies about how he had been abandoned and broke him in body and spirit, the small child pushed Stealth away to the point that he outright forgot that Stealth was around. For many years, Stealth lived in silence, immensely unhappy with their situation. When Kage was rescued by Leon at the young age of 16, Stealth began trying to repair their relationship once Kage felt that he was trustworthy enough. Unfortunately for Stealth, his taunting nature often reminded Kage of Reishiki's unbearable attitude and serve-me-or-die motto. In the end, while tolerated, Kage shows no trust for Stealth; especially after Stealth possessed him for a time in order to act as he wanted to for a year or so.
Stealth is rarely out and about in the acres. However, should one get close enough to him, they might be surprised to learn that Stealth treasures family above all else, though those who become 'pack mates' will gain his protectiveness too. Sharing his brother's sometimes extreme attitude when it comes to bailing loved ones out of danger, while selfish and even cowardly at times, Stealth can be an invaluable partner and friend.
In his original life, he was a black kitsune that went by the name Vulpe. By this point in time, he's forgotten most of his past life, given that he lived with Kage far longer than he actually lived his own life.
