Kara Actuation Arc
Using their female disguises, Asaka and his brothers attempted to seduce Kirisaki to learn of the location of the cell of Hashirama Senju. 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, Asaka and his brothers tracked them to learn that Sakuya had the cell in her possession. Asaka, Hiruga and Yūga successfully sneaked into the castle, only after Yoruga's failure to bypass the barrier ninjutsu surrounding the castle. Asaka and Yūga managed to locate and kill Sakuya and claim the cell. Boruto arrived and using the opportunity for a getaway, they framed him for the deaths of Sakuya and her butler, but not before the latter alerted the castle guards of her death and alleged culprits. Having successfully escaped the village, Asaka and his remaining brothers mourned Yoruga.
