Lu Meng appears in the anime as Ryomou Shimei, reflecting the Japanese adaptation of his Chinese historical identity. He serves as a military commander within the Wu forces under Sonsaku Sonken's leadership. As one of Wu's "Six Steeds," he plays a significant role in key battles, including defending against invasions at Changjiang.

A dedicated episode, Episode 20 "Amou of Go Rises from Obscurity by Using His Young Wisdom," focuses on his development. This title references his historical nickname "Amou," initially denoting perceived lack of scholarly refinement. The episode depicts his evolution from a solely martial warrior into a more intellectually adept strategist, aligning with his superiors' encouragement to pursue scholarly development alongside military duties.

Within the narrative, he interacts with fellow Wu officers like Rikuson Hakugen. His military contributions occur within the broader campaigns of the Wu faction. The anime portrays him consistently as a dedicated officer contributing to Wu's strategic objectives throughout the series, departing from historical accounts by not depicting his death or illness.
