Chōryō, also called Zhang Liang and Renhō, is the youngest of the three Chou sisters. Alongside Chōkaku and Chōho, she uncovered a military strategies book and applied its teachings to attract followers. Their actions unexpectedly positioned them as leaders of the Yellow Turban Rebellion. Despite their aims, their command sparked chaos, ending when the warrior Ren obliterated their 10,000-strong army alone. After this defeat, the sisters vanished and were presumed dead.

Karin later recruited them by exploiting their past failures, forcing them into her service. Their duties involved raising morale and recruiting soldiers through public performances. Within this structure, Chōryō functioned as the group's lead strategist and manager. She restrained her sisters to prevent further disorder and managed critical logistics, including treasury operations and organizational control.

Publicly, she adopted a calculated cute-younger-sister persona to charm fans and supporters, deliberately contrasting her typically serious and level-headed nature. This performance-driven charm underscored her pragmatic and consistently deadpan personality, reflecting her role as the sisterhood's stabilizing anchor.

Physically, she sports short light purple hair and blue attire. Her distinctive glasses reinforce her studious, analytical image. During a confrontation with Kan'u, these glasses shattered, symbolizing a moment of vulnerability.
