Aladdin, a young thief boy under ten years old, resides in Baghdad and debuts in the series' second episode. Upon protagonists Hayato and Yumi's arrival in the past, he forges a close bond with them, affectionately addressing Hayato as "big brother." This connection leads him to take up residence in Princess Shalala's palace, integrating into its environment. During the eighth episode, he gains a dragon child companion named Doramusko. Aladdin primarily navigates Baghdad's challenges alongside Hayato and Yumi, frequently interacting with figures like Princess Shalala and Prince Dandarn.
