After his transformation into a Jūnin, he wears a sleeveless purple vest with white fur cuffs and the emblem of the moon sewn into the chest-area. He also wears a black headband, with what appears to be a horn on it, on his head.

Personality
Since first appearing on the scene, Raian has remained a mysterious figure no matter who he appears to; always seemingly hiding his true self. He is commonly viewed as a person who cares solely about his younger brother, however, a quick look at what he's really thinking reveals that he is greatly hurt by some of his younger brother's actions and words, more so than he gives off. Yet, surprisingly, he truly seems dedicated to his brother and will go out of his way to keep him from harm.

As a Substitute Shinigami, he possesses a great amount of self-control both over his emotions as well as his actions, constantly showing a heartless behavior. He has only shown surprise if an opponent or ally has shown more ability than he had originally deduced them to have, yet even in these situations he doesn't allow himself to lose his composure. Raian does not seem to possess any form of arrogance, and will only make a statement if he can back it up with his own power, and is even not above complementing an opponent when they show their occasional strokes of brilliance.

As an addition to being an incredibly powerful Shinigami, Raian has demonstrated equally impressive intelligence, especially when it comes to powers, and can often appear to be very wise despite his young age. He is noted to be very observant, being able to deduce the nature and power of an opponent's technique simply by seeing it once, leading to him rarely being surprised or caught off guard. Due to his past, he shows no love of battle or bloodshed and will do anything to avoid it.

Raian also is a very respectful person, calling his longtime best friend Seireitou Kawahiru, "Seireitou-sama", out of respect for Seireitou's position as a member of the Kawahiru Clan. This sets him apart from the only other known Substitute Shinigami,, who disregards honorifics for no true reason at all.

Above all, he is a loyal friend, and will come to the aid of any person whom he calls a friend. He is often seen as coming to the aid of his friend Seireitou and his younger brother, no matter the danger.

Powers & Abilities
Βecause he was not raised in Soul Society, he has not received any formal swordsmanship training and therefore all of his swordsmanship skills have been self taught. He is capable of holding his own against the likes of Seireitou Kawahiru and Sao Feng in swords combat, demonstrating the capabilities of his self-taught swordsmanship. His moves are very quick and precise, and upon finding an opening, he will impale his foe several times, ending the fight as quickly as possible.

Immortality: Like their archenemies, the Togabito, a Tsugunau's, Raian included, life can never be expended. When dealt a fatal wound, they return to heaven for many centuries for recovery.

His spiritual power is noted to feel very cold, sending chills down the spine of whoever feels it. In some cases, depending on how much reiatsu Raian lets out, his spiritual power alone can summon rainstorms which vary in intensity; a possible reference to his Zanpakutō, which can also control rain and storms. When active, his reiatsu appears as a white outline around his body, as well as wisps of white energy that float off of his body, like mist.

Yūbi (優美, Grace): The defensive ability of Tsugunau. In order to use it, they must use some of their own blood. Afterwards, they can summon a barrier to protect whomever they wish. The strength of the barrier is up to the user.

Enhanced Speed: Though he has never been taught a technique, such as Shunpō, he has shown incredible speed-levels, capable of keeping up with and, in some cases, outrunning captain-class enemies. He does this by pumping raw spiritual power into his leg and feet muscles and using it to propel him in the direction he wants to go. There seems to be two levels; the first appears just like shunpō and sonido. The second level allows a Tsugunau, with enough focus, to instantaneously transport to any location they wish.

Master Tactician: Raian has been noted on numerous occasions to be a genius when it comes to forming battle tactics as well as analyzing other's battle strategy. He can deduce the nature, power, and effects of an opponent's technique simply by seeing it once. He is easily able to recognize danger and prepare himself well ahead of time. One of his greatest skills is to create several strategies before entering the fray and executing them flawlessly, switching to a different strategy if his initial one fails to meet his expectations.
