While Leona waits, Mika (Flare) escapes with Sanpei's help. Garunte, determined to reclaim Flea, empowers Hysteria to revive demons defeated by Leona in the past. Leona is now confronted by eight demons simultaneously, a challenge even with only one present. She manages to get Flea and Sanpei to safety, but they are captured. The demons relentlessly pursue Flea, fueled by past grievances and blame. What will become of Leona?
