To the untrained eye, this seasoned butler is simply a skilled household manager within the Demon King's Castle. In truth, he is a retired legendary archer once feared under terrifying epithets such as 'One-Shot Kill.' Equally adept at intelligence gathering and logistical coordination, he keeps the entire castle running with quiet efficiency. Though composed and astute by nature, he has a knack for delivering razor-sharp quips at the female knight's expense. When the Hero and Demon King forged their landmark pact to reshape the world, his wealth of hard-won experience and formidable combat prowess became an indispensable pillar supporting their shared cause.
