Laojiu appears exclusively in the anime adaptation, created solely for that medium. He holds the esteemed position of senior disciple at Dairin Temple, cultivating an erudite and refined demeanor. Narratively positioned as Chinmi's rival within the temple's training environment, he provides a deliberate counterpoint to the protagonist's instinctive martial arts approach. His inclusion stems from creative decisions made during the anime's production, enriching the temple's hierarchy and interpersonal dynamics beyond the original manga's scope. His presence shapes the anime's unique storyline and character interactions throughout its episodes.
