“Would you like me to attend to you tonight?”

Mio, previously known as Black Spider of Calamity, is one of the two main female deuteragonist in this series. She is a unique existence in the Goddess' World. She is presently in servitude to Makoto Misumi.

In her human form, Mio has black hair with a red headband knot in bloom, black lace gloves and wears a luxurious black and red kimono in the style yukata, further the handle have white frills. However, do not be fooled by her, her kimono still has some defensive power, it can withstand up to a certain point enough to surprise the elders dwarves when it got cut up. She hides her folding fan in her bosom. At a simple glance, it doesn’t look like the type that someone could properly move in.

Meanwhile on Mio's everyday/default outfit (which started on Season 1 when Makoto liked the outfit), Mio wears her usual black and red kimono but with modifications. She now wears black shoes instead of her usual white shoes and the kimono is fully covered. Her white frills got removed and it now consists of two spider-webs on her left arm and her legs. She also wears her default black lace gloves throughout the series as her accessory. On the other hand when she cooks, she wears a white apron on her kimono.

In her form as the Black Spider of Calamity , she is a giant purple-black spider with a sinister aura, with 8 very large, strong and hard legs, capable of destroying and piercing concrete foundations and even normal metal. She has 8 yellow eyes, of which the 2 central ones are the largest, and very sharp teeth, which are hidden in her 4 very large and sharp jaws.

She can be single-minded and straightforward in her loyalty to Makoto to the point that it reaches a dangerous level. Can be very instinctual, intelligent, and can learn how to do things quickly like cooking food for Makoto.

She has no qualms about destroying anyone who intends to do harm to Makoto, regardless of their identity, position, or background.
