Yukari Mishakuji, once a vassal to the deceased 7th Colorless King Ichigen Miwa, served as the senior pupil to Kuroh Yatogami under Ichigen's tutelage. He later rose to a high-ranking J-rank position within Hisui Nagare's Green Clan. Standing 185 cm tall, Yukari sports purple and blue shoulder-length hair, brown eyes, and favors cosmetics like lip gloss. His attire typically features layered purple shirts, black pants, boots, studded gloves, and a leather-trimmed jacket designed to hold his sword sheath. He displays a flamboyant, narcissistic personality, dedicating significant time to skincare, perfumes, and appearance. Yukari frequently uses feminine self-references and appends "-chan" to others' names. Despite this effeminate demeanor, he exhibits ruthless combat prowess, openly stating satisfaction only when "at least one head rolls." He intensely values beauty and employs his well-read, eloquent nature to unsettle opponents. Although he once considered Kuroh a brother figure, he attempts to kill him without hesitation during confrontations. Yukari maintains respectful, amicable relations with JUNGLE members like Gojo Sukuna—whom he teases for impatience—and Kotosaka. Deep respect for Ichigen Miwa endures despite his departure from the Colorless Clan; he avoids discussing Ichigen to provoke Kuroh and once expressed condolences over the king's death. His service to Ichigen ended when Yukari attempted to assassinate his mentor, rejecting Ichigen's "safe path" philosophy in favor of a vivid, unpredictable existence. During this lethal challenge, Kuroh intervened, but Ichigen directly engaged Yukari—sustaining his first known combat injury. Defeated, Yukari thanked Ichigen and departed peacefully. He subsequently joined the Green Clan and developed an aversion to Christmas stemming from unresolved youth relationship troubles. In *Missing Kings*, Yukari participated in JUNGLE's assault on the Gold Clan's tower, effortlessly defeating elite fighters. He later confronted Kuroh, Neko, and Anna Kushina, quoting Ichigen's poetry to provoke Kuroh. Their battles demonstrated Yukari's combat superiority; he overpowered Kuroh using both Colorless and Green Aura, taunting him about the "emptiness" of his sword compared to Ayamachi, which embodied Yukari's passions and ambitions. He retreated only after the Green King ordered Anna's abandonment following her ascension as Red King. During *Return of Kings*, Yukari monitored conflicts involving HOMRA and Scepter 4, dismissing Sukuna Gojo's plans to lure the Silver King as ineffective. He privately cautioned Nagare that the Silver King could threaten the Green Clan due to Nagare's "zero chemistry" with him. In *Seven Stories*, specifically *SIDE:GREEN ~Overwrite World~*, Yukari served as JUNGLE's strongest combatant. Sukuna Gojo challenged him to earn Nagare's audience, though the outcome remained undisclosed. The narrative explored Sukuna's backstory as a runaway adopted by JUNGLE, with Yukari's role consistent with his established loyalty to Nagare. Yukari wielded both Colorless Aura (inherited from Ichigen) and Green Aura (granting electrical manipulation and shapeshifting). His swordsmanship surpassed Kuroh's, incorporating dramatic flair. His sword, Ayamachi ("fault" or "error"), gifted by Ichigen, resided in a purple sheath on his jacket. Yukari claimed it contained his entire being—"joy, anger, sadness, happiness, fear, hesitation, shock, madness, anxiety, pride, honor, and love"—contrasting it with Kuroh's "empty" blade. The spin-off *The Idol K* reimagined Yukari as part of an idol group led by Nagare Hisui, depicting no substantive character development or backstory in this setting.
