Kara Actuation Arc
Hiruga and his brothers were given a mission to retrieve the cells of the First Hokage Hashirama Senju, which made its way into the black market in the Land of Silence. Using their female disguises, Hiruga and his brothers attempted to seduce Kirisaki to learn of the location of the cell. However, he lost interest when Boruto Uzumaki arrived himself taking the appearance of a woman.

Witnessing Boruto and his comrades taking away an unconscious Kirisaki, Hiruga and his brothers tracked them to learn that Sakuya had the cell in her possession. Hiruga, Asaka and Yūga successfully sneaked into the castle, thanks to Yoruga's sacrifice to bypass the barrier ninjutsu surrounding the castle. Hiruga took the appearance of a female servant to alert the butler of the intruders. After the butler saw Boruto as Sakuya's "killer", he alerted the castle of her murder, and afterwards was also killed by Asaka to frame Boruto for their deaths. Before their escape, Hiruga threw a glass bottle containing strong perfume at Boruto to make him easy to track for the village. Having successfully escaped the village, Hiruga and remaining his brothers mourned Yoruga.

While making their way back to their country, Asaka learned they were being followed, and in order for their mission to be a success, Yūga stayed behind to stall their pursuers. Hiruga and Asaka parted ways with Yūga as he stalled for success.
