Xyz Dimension Arc
Sayaka and Allen reunited with Shun, who got transported back to Heartland along with Yūya, Gongenzaka, and Shingo. The three of them then looked for Yūya and the others, arriving just in time to stop the Duel between Kaito and Yūya. Together with Shun and Allen, she assured Kaito that Yūya and the others are a few allies that Shun brought with him to help hem. Sayaka asked Kaito to return and fight together with them again, but Kaito refused and left the scene.
