Yui Yashiya

Yui Yashiya holds the position of the No. 1 executive within the Oni Island Alliance, standing second only to the organization's leader in terms of combat ability. She harbors an intense sadistic streak, finding her greatest pleasure in dominating powerful opponents and breaking them mentally. After being exposed to protagonist Rokudo's onmyoji techniques, she developed a warped form of affection toward him, expressing this twisted love through acts of torment. In battle, she methodically identifies and exploits enemy weaknesses, making her one of the most formidable threats in the series.
