Ariu Mikaboshi | Kagurabachi

Name: Ariu. Last Name: Mikaboshi. Age: Unknown. Height: 195 cm.

Affiliation: Mikaboshi Occupation:

• Crown Prince of the Mikaboshi
• Mikaboshi Guardian

Eye Color: Black-green. Hair Color: Black. Sorcery: Sumika.

Appearance: Ariu is a tall man with black eyes and black hair, mostly slicked back, with some strands framing his face. His eyes have several lines that run to the edges of his face, resembling cracks. Like all Mikaboshi, Ariu has black fingernails. Ariu wears black robes and white pants with black shoes, with his right shoulder armored with a pauldron, a tassel on the end of it. A rope connects from the shoulder pauldron to Ariu's Datenseki brooch, from which dangles another tassel. Ariu wears arm bracers on his forearms, which he frequently uses for defense. While Ariu's clothing mostly matches that of other Mikaboshi soldiers, Ariu's robes do not close to armor around the neck, but instead appear as a simple high collar. Ariu's Datenseki brooch is also pinned to the left side of his torso, rather than directly below his neck.

Personality: Ariu is a cold individual who maintains his composure to accomplish his tasks with cool efficiency, his foremost task among them acting on behalf of the Mikaboshi. As the Crown Prince of the Mikaboshi, he has shown a clear dedication to supporting his people. During a ritual where Ariu met with his fellow guardians among a crowd of his people, Ariu took the time to reach out reassuring hands to the people, while maintaining that they would not starve, and they would prevent the enemy from obtaining their sacred stone. Against the Japanese, Ariu has operated with an entirely cool and ruthless demeanour. He has no qualms with killing the Japanese, but only so much as is practical. During the Irishima Talks, he arranged the destruction of the Japanese delegation's escort ship and killed all but one of the delegates in order to ensure exactly one delegate was available to convey demands to. Ariu is also straightforward and direct, stating that refusing the Mikaboshi's demands would cause them to resort to force. Even in the face of hostile threats, Ariu remains completely unfazed. When Shiba called out the Mikaboshi by name, Ariu took the Japanese's knowledge of their identity in stride and immediately pivoted to justifying their actions through history. He has shown little to no concern regarding injuries, registering his severed fingers with barely a glance and continuing to speak. During his later battle against the Japanese sorcerers, who are among the strongest the Japanese could muster, Ariu was entirely unconcerned and did not expect to even have to fully access the power of Sumika. When Yoshinojo Soga identified how Sumika was modifying the environment, Ariu merely narrowed his eyes. Only after Hiroto Soga and Shuji Mashiro launched the wreck of the ship at the island did Ariu show strong reaction in combat, visibly wincing as he regenerated and struggling in irritation and frustration. Ariu holds a particular enmity against the Soga Clan, for being the ones to sink their ancestors into the ocean. He instantly identified Kurotsuchi as the power responsible when used by Hiroto, and voiced that all the Japanese needed to do to see their motivation was to look to history. He views that the Princess Soga of over a millennia ago had falsely accused them of aggressive actions, which led to the Mikaboshi being sunk; thus in the present, he desires vengeance upon them.

Overall Abilities: As the Crown Prince of the Mikaboshi, Ariu holds significant influence over his people. He is also one of the Mikaboshi's six guardians, who are said to wield power equivalent to the king who built the Mikaboshi's underwater country; the True Realm of the Datenseki, which can modify the environment itself. Ariu was able to handle the attacks of all four Japanese sorcerers at the Irishima Talks. As a sorcerer, Ariu has accomplished the first stage of spirit energy usage, being able to use his spirit energy to strengthen his body to superhuman levels. Like all members of the Mikaboshi, he is able to use the immense power of Datenseki without fear of backlash. Ariu is particularly adept at using Datenseki to amplify his speed, able to perform feats of superhuman speed even greater than that of ordinary sorcerers, impaling Mashiro in an instant and often moving short distances without opponents being able to react. Ariu's attacks are of such speed that they can even appear as many strikes being conducted at once.

Enhanced Durability: Ariu possessed tremendous durability, able to endure the powerful crushing gravity of Kurotsuchi, and multiple attacks from Shuji Mashiro's sorcery, Akuu. Even after being directly impacted by the Haruma, which caused a massive crater on Irishima, Ariu's body remained mostly intact, though Ariu was grimacing and visibly wounded afterwards.

Enhanced Speed and Reflexes: Ariu is extremely fast, able to ambush Mashiro and impale him in an instant. With the assistance of Sumika nullifying his opponent's senses, he is able to even outpace users of Kurotsuchi and Itazura, striking them numerous times before they could react.

Enhanced Strength: Ariu possesses immense strength, able to crack the earth with his blows and hurl an opponent from the center of the island of Irishima to the edge in a single blow.

Sumika:

A sorcery technique Ariu has used by accessing the True Realm of the Datenseki, which is shared by the other Mikaboshi guardians. Its activation is signified by one of two spirit energy manifestations appearing nearby; either a white centipede around Ariu's person when only Sumika's ability to negate sorcery is accessed, or a large scorpion with a centipede-like body appearing above him when Sumika's power is accessed in full.

Sumika's main ability generates piercing holes directly located on targets, and has been described as a power that destroys the enemy. Sumika's side effects involve Ariu passively altering the airspace around him to benefit himself and hinder opponents. Sumika clouds the senses of nearby targets, therefore rendering it significantly more difficult for them to react and adapt to his movements and evade his high-speed attacks. Sumika additionally prevents sorcery from affecting Ariu and allows him to regenerate from his injuries, as well as heal targets he chooses. Sumika's healing is able to recover its user from even normally fatal wounds. Activating immunity to sorcery requires the user to call Sumika's name and is indicated by a visible change in the surroundings and a spirit energy manifestation. However, users can access the ability to heal themselves and dull the senses of those around them without any obvious tell, allowing the user to ambush foes who may believe the user dead.

Past:

Ariu Mikaboshi was born into the Mikaboshi's royal family. As he was born within the Mikaboshi's underwater country, he held a natural ability to use the Datenseki. Due to his bloodline and prayers, Ariu became one of six individuals known as the Mikaboshi's six guardians, who can access the Datenseki's True Realm much like their ancestor who constructed their underwater residence.

Sometime in the past, Ariu walked through a crowd of his people surrounding a pavilion, extending his arms to contact theirs. As his people prayed, Ariu assured them they would not starve and that he would ensure the enemies did not gain access to the Datenseki. He approached the pavilion, where another individual ground up insects within a jar into a paste, before Ariu consumed the contents of the jar and activated the Datenseki's power, as did the five other guardians around him, all six rising into the air.
