Jericho

Jericho is an apprentice Holy Knight assigned to guard Baste Prison, born on September 6th, standing at 160cm and 18 years of age. Bearing silver-white hair in the manga and Alice blue in the anime, she carries herself with fierce pride — a pride that Ban shattered when he mistook her for a man during his prison break, wounding her dignity deeply. Driven by the desperate need to prove herself equal to her elder brother Gustav as a Holy Knight, she consumed the blood of a Demon, transforming into one of the "New Generation" and gaining mysterious power capable of halting or slowing the healing of wounds — even bypassing Ban's legendary immortality. Alongside Guila, she crashed the Vaizel Fighting Festival, demanding Ban take responsibility for stripping away her femininity. After the Seven Deadly Sins rescued Elizabeth Liones, she confessed to Guila her true motive — to stand beside her brother as a fellow knight. However, when Hendrickson unleashed a forbidden spell causing the Demon's blood within her to rampage, she transformed into a monster and gravely wounded the very brother she sought to impress. It was Ban who ultimately extracted the Demon's seed from within her, restoring her — yet at the cost of her power, and unwittingly, her heart. She subsequently trailed Ban and King to the New Fairy King's Forest, where Escanor came to her rescue and she forged an unlikely friendship with Elaine. Following Gustav's death, Jericho awakened to a new magical power — Ice Fang — and with it, seemed finally freed from her obsessive feelings for Ban. She vowed to surpass her late brother, taking her place as commander of the North Gate in the defense forces. In a side story, upon learning from Elaine that Gustav had lingered as a ghost after death, she fled in absolute terror — a rare, unguarded glimpse of the girl beneath the armor.
