Unkai Kurama in Naruto

Unkai possesses an unwavering loyalty towards his clan, placing it above all other considerations, including the life of his own flesh and blood, his niece Yakumo. Despite the tragic demise of Yakumo's parents, he relentlessly campaigned alongside other members of his clan to have Yakumo killed. However, their efforts were thwarted by the Third Hokage, Hiruzen Sarutobi, who denied their plea, leaving them with no choice but to abandon their ill-fated attempts.

After the tragic incident that claimed the lives of Yakumo's parents, Unkai became convinced that she posed a grave threat to the village due to the dark entity that resided within her unconscious mind. Despite Yakumo's powers being sealed away, Unkai feared that the beast would continue to grow over time, endangering the lives of all those around her. Unkai enlisted the help of his fellow clan members to launch a full-scale attack on Yakumo's compound, determined to capture her and neutralize the threat once and for all.

However, their plans were foiled when Kurenai Yūhi arrived on the scene and whisked Yakumo away to safety. Unkai pursued them relentlessly but was eventually intercepted by a group of skilled ninjas, including Naruto Uzumaki, Sakura Haruno, Hinata Hyuga, Shino Aburame, Kiba Inuzuka, and Might Guy. Despite putting up a fierce fight, Unkai was ultimately forced to retreat.

Soon after, the group found themselves trapped in Yakumo's genjutsu, unable to escape its clutches. Unkai reappeared, explaining Yakumo's troubled past and helping the group find a way out of the illusion. In the process, Unkai sustained severe burns from Yakumo's powers, requiring immediate medical attention.

While Naruto and Kurenai worked to help Yakumo come to terms with her abilities and put an end to the dangerous entity within her mind, Unkai remained behind to receive treatment for his injuries. Under the skilled care of Sakura and other medical-nin, he was able to recover and ultimately played a pivotal role in helping to save Yakumo and the village from impending disaster.

Unkai's unwavering loyalty to the Kurama clan has been demonstrated through his readiness to take drastic measures to protect them from any perceived threats. He is a resolute man who is not hesitant to use lethal force, even if it means taking the life of one of his own clansmen, as he had once advocated for the elimination of his own niece Yakumo.

Despite his seemingly harsh actions, Unkai's actions were fueled by his deep-seated concern for the welfare of the Kurama clan, which he holds in the highest regard. His fierce devotion towards his clan has earned him the title of a father figure by Yakumo, who recognizes his unconditional love and support for their clan.

Unkai is an old man with a short crop of light-brown hair, small-dark eyes, and thick eyebrows. He was seen dressed in kimono-like attire.

Unkai demonstrated his natural leadership skills among his fellow Kurama clan members, who looked up to him and followed his directives without question, even when they were involved in taking action against their own comrades.

Moreover, Unkai possesses a highly developed sense of smell, which he utilized to great effect during his battles. He was able to locate Kurenai Yūhi, who was attempting to camouflage herself, by using his keen sense of smell to track her movements, demonstrating his exceptional tracking abilities.

Being a member of the Kurama clan, Unkai is a formidable genjutsu user, possessing an innate ability to manipulate illusions to his advantage. He has even proven his skills by managing to break free from the powerful genjutsu of Kurenai Yūhi, although he ultimately had to abandon the fight and retreat. Nonetheless, his impressive skills earned him the respect and admiration of Kurenai, who praised him for his abilities.

Similar to other individuals hailing from the Kurama clan, Unkai's given name is also associated with the concept of clouds. Specifically, "Unkai" translates to "a sea of clouds.
