Medusa can be briefly described as the typical yamato nadeshiko or ideal wife, which is especially noticeable in her relationship with Jashin. She is emphatically polite and kind, exerting an exceptionally positive influence on everyone around her. When sufficiently angered, however, Medusa goes into "Passive-Aggressive Mode", in which her mood is eerily calm, and she speaks in a more polite dialect.Her crown is actually a family treasure. Medusa has a night shift with her two sisters which involves searching for lawbreakers. She seems to have only allowed Jashin-chan to know about it, with the latter unaware it was supposed to be a secret.Medusa is a cute girl with pale skin, short light purple hair with a cowlick, and same color eyes. Earlier in the manga, Medusa wore a simple one-piece dress based on the Roman ages, but after leveling up, her attire changes, now wearing clothes with an Egyptian motif. She always wore a paper bag on her head so that no humans turned to stone. " Hi...I'm Medusa. It's a pleasure to meet you".
