Mitsuki's Disappearance Arc
Kirara appeared alongside her allies Sekiei and Kokuyō when they were leading Mitsuki to the Land of Earth. She went ahead on her own after her genjutsu on Yurito was broken. As the group made their way to the Land of Earth, Kirara separated from the group to meet with their leader Kū. Later, after Kū abducted the Fourth Tsuchikage, Kokuyō return seeking help for the weakening Sekiei. She and Kakō joined him to help. Midway, they found Mitsuki approaching them while carrying Sekiei. While Kirara and the others grew suspicious of Mitsuki, Sekiei vouched for Mitsuki, insisting that the young boy truly came of his own free will to learn who he really is.

Later, to keep Kurotsuchi's abduction a secret, Kirara placed Kontsuchi under a genjutsu to answer all calls for the Tsuchikage and tell them she was away on a private mission. After Ōnoki, Kū's master, went missing, Kirara was tasked with using her genjutsu on any suspicious villagers to keep things quiet. Before she could start however, her body began breaking down, requiring treatment. Soon afterwards, her faltering was caused her various genjutsu on Iwa officials to fade, forcing Kū to take control of the village publicly. Once succeeding, the artificial humans began growing irritable at Kū's refusal to try a human heart transplant on them, which could likely save their lives, on the grounds that hey did not yet have Ōnoki's permission. They were then tasked with finding Ōnoki.

Later, Kirara found the Konoha-nin's hideout, disgusted at the sight of the imperfect Akuta named Akkun, being so passive with the enemy. While Inojin tried to defend his new friend and seal her, Kirara quickly subdued him with her genjutsu. She used him to catch Boruto Uzumaki off-guard and subdued him. With an overwhelming number of Akuta at her command, she decided to take the captured genin back to Kū.

When returning to the village, Ōnoki was visibly horrified by the hostile takeover of the village. When approaching Kū, the second-in-command voiced his plan to transplant human hearts into the fabrications to sustain them. The elder however refused on the grounds that it went against the purpose of his goal for saving lives. Deciding that Ōnoki was to sentimental to see the bigger picture, Kū usurped the Third Tsuchikage. Before Kū could move forward with his plan, Shikadai appeared, using a diversion to help his friends escape.

As the Ino-Shika-Chō trio decided to face off against Kokuyō, Boruto and Sarada were forced to face Kirara, who voiced her desire to take Sarada's glasses which they would look prettier on her. Quickly, she subdued her foes with genjutsu. Kirara decided to play with Boruto and Sarada like dolls by forcing them to fight each other. She also forced Boruto to shut his eyes when Sarada attempted to use her Sharingan on Boruto to break the genjutsu. Kirara was later informed by an Akuta that the artificial heart was completed. Not wanting to miss it, she made Boruto and Sarada stop holding back before leaving. After Kirara arrived with Mitsuki and Sekiei, she stared at the completed artificial heart with amazement and couldn't wait to have her own heart. When Boruto and Sarada arrived to stop Mitsuki from giving Kū the heart, she was surprised to see the two escaped from her genjutsu. Kirara later witnessed Mistuki's betrayal after he gave Kū his heart, revealed to be disguised snakes.
