Gentle Foolish Lies (S01E11)

During the intense battle against the demons on the artificial island, Kisara is suddenly pierced by a spear right before Shu's eyes. Just when all seems lost, Ayano and Sharon swoop in to save her, forcing Shu to retreat from the fray as he spots someone he has been desperately searching for—his younger sister, Kanna. Despite humanity's fierce resistance, supported by the efforts of Bayron City, their struggle proves in vain as Kanna, now recognized as an S-Class demon, unleashes widespread devastation. Kisara succumbs to her injuries and loses consciousness, leaving Shu paralyzed with despair as he watches her. In response to his anguish, Kisara stirs awake gently.
