Shumai, a young martial artist rescued from thugs, becomes Ramenman’s steadfast companion, united by their shared loss of family to the Cobra Gang. Under Chen Zongming’s mentorship, he dedicates twelve years to mastering Chojin Kung Fu’s Essential Battle Dragon style, developing lethal techniques like the Spinning Dragontail Kick (Kaiten Ryūbi Kyaku), Ranged Solar Kick (Rekka Taiyō Kyaku), and Swallow Whirlwind Kick (Hien Senpū Kyaku). Though his playful demeanor occasionally sparks chaos, Shumai’s combat intellect shines in battle, where he devises crucial strategies against adversaries. His journey oscillates between hunting Cobra Gang remnants and forging his identity, evolving from a spirited sidekick into a seasoned warrior through relentless training and clashes. Later narratives position him as Ramenman’s protégé, expanding his role beyond initial exploits. A reimagined incarnation anchors a franchise backup story, while a video game trial allusion nods to his enduring legacy. Shumai’s growth charts a path from traumatized orphan to composed martial artist, balancing tactical brilliance with levity. His dynamic with allies and enemies alike underscores a duality—both counterpoint and complement to Ramenman’s gravitas—cementing his place as a resilient figure within their shared saga.
