The kanji 役 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is 彳 (gyō-nyō), which is the "walk" radical, and it implies movement or action, and the right side is 殳 (motsu, meaning weapon), which is a "weapon" radical and is associated with the idea of a strike or blow, and it has a phonetic component. This character was developed from the ancient meaning of "to serve or to perform a service," possibly in the sense of military service or combat. The combination suggests someone taking action and fulfilling a role or duty, often in a context that requires exertion or commitment.
