Appearance
Tsumugi is a tall young woman with long, knee length, cerulean hair which starts smooth and becomes wavy the lower it goes. Her eyes are a soft teal and round. She wears rimless glasses with white temples.

Her uniform consists of a knee long pleated skirt, adorned with six white buttons on her waist, her skirt seems to be held by suspenders. She wears an orange bow, black socks ending under the knee, and grey shoes. Her blazer has two pockets on both sides and is adorned by the same white buttons as her skirt.

She has been shown without her blazer in her promotional artwork, which shows an insignia of sort on her left breast.

Tsumugi states as a rather normal and plain-looking.

Personality
Tsumugi is an honors type student who speaks in a docile and gentle way, but she becomes very passionate when she talks about her favorite series or cosplays, having a habit of slipping in famous quotes from various sources into conversation.

Tsumugi also tends to ignore people while she's in her thoughts, no matter how many times they try talking to her.

While Tsumugi is the Ultimate Cosplayer, she only enjoys making costumes, not wearing them. She is not really fond of people looking at her. However, she hates using cosplayers who care more about standing out than love of the series, so she wears her own costumes as well, with love. So in that case, she likes people looking at her when she wears her own costumes with love. She deeply loves cosplaying as she states that cosplaying is an expression of love.

Ultimate Cosplayer
Despite her status as the Ultimate Cosplayer, Tsumugi actually doesn't have interest in cosplaying herself. Rather, she states that she enjoys recreating costumes more. She loves to create costumes, because it is like making a fictional character real, in a way. She is so popular that she has a corporate sponsorship so she became able to use even the most simply expensive materials without restraint. She states that they have as many people as the amount of people who came to see the first panda coming to Japan.

In her promotional artwork, Tsumugi is featured with mannequins wearing lingerie and a wig, several paints and cosmetic brushes, as well as red thread and an object which could be interpreted as scissors. This could imply that her talent is multi-faceted.

She is also a well versed otaku in anime and manga references.
