Gloria Sato is a main character of Big City Greens. She is a barista at the cafe next to the Greens' house, who aspires to go to Paris, and often has to deal with Cricket's shenanigans, but soon they become friends and co-workers.
She’s a very tall, thin and slender young woman who has light purple skin, and blue hair.
She wears a pink t-shirt, purple pants, and black slip-on shoes. She also wears her hair in a ponytail.
On special occasions (Paint Misbehavin' and Valentine's Dance) she'll dress up nicely. She has a red vest, a pinkish skirt, orange-brown sandals, yellow earrings and a black hair tie instead of her usual pink one for the art gallery. For the Valentine's dance, she wears pink dress, with a white lace in the middle, black heels, white earrings, and her usual pink hair tie. For the open mic night, she has a black sweater.
In a photograph taken with her parents sometime before she left for Big City, she had a turquoise vest and jeans.
Gloria is a hardworking, though very stressed, cafe girl. She gets irritated with the Greens when they mess up her cafe. Already quite stressed due to the load of her job, Gloria can quickly lose her patience, especially when it has something to do with Cricket's shenanigans. However, she can stoop to Cricket and Tilly's level of childishness such as when she stole their critterballs out of spite and eventually started playing with them before almost getting fired by her boss ("Critterball Crisis"). Once Cricket begins to work at Big Coffee, she is still somewhat annoyed by his antics, but has cooled down and has developed something of an older sister attitude to the boy.
Gloria dreams of making enough money so that she may see Paris, which she has a romantic view of to the point of Paris Syndrome and is why she doesn't want Cricket to jeopardize her dreams. She has an artistic side, as revealed in "Paint Misbehavin'", and has dabbled unsuccessfully in abstract art.
She is also very stressed and uncertain. When she describes projecting her feelings in abstract art, she says that she has "Hopes and dreams and failures and insecurities and emptiness and loneliness and darkness and endless trying to no avail and dreams being crushed...", showing just how down and depressed she can get.
But, in "Critterball Crisis", things changed; after taking away his "Critterballs", Cricket tried to take them back, and a massive "Critterball" war takes place, which nearly loses Gloria her job. Cricket, having learned a bit about Gloria and her dream of going to Paris, realized the error of his ways, offers to pay the debt by working at Big Coffee.
From then on, the two work together in Big Coffee. While they still butt heads, the two have grown fond of each other and have developed a sort of Little Brother/Big Sister dynamic.
In "Parade Day", Gloria is left by Cricket to deal with the busiest day of the year, but he comes back later, parade in tow, and lets her get a break, realizing that they are dependent on each other.
In "Paint Misbehavin'", the two discover they share a love for art (Cricket through doodles and Gloria through Abstract art) and try to use it to sell paintings. After Cricket betrays her for a place in a fancy art exhibit, Gloria goes over there to see him fail. Cricket fails, but then realizes that it only worked when the two worked together, and they finally team up. They get kicked out, but still enjoy themselves.
In "Coffee Quest", Gloria is relieved that Cricket will finally leave Big Coffee, but to get there they must retrieve the last coffee bag in the city. While they undertake this dangerous quest, Gloria reveals to Cricket that she actually comes from the suburbs, and that she just wants to belong and be a city girl. After bonding in their quest, and realizing that they do enjoy working together, Gloria and Cricket mess up the café so that they can keep being a team.
In "Valentine's Dance", Cricket bumped into Gloria after running away from his desires for Gabriella. After learning that she had a date, Cricket asked her what it felt like. Gloria's frightening description of what was going on through her mind was matching Cricket, who was scared of getting hurt by love. After she teased him, he ran off to hide.
Later, Cricket, having had enough of his confusion, tries to turn on the sprinklers so that the dance will end. When Nancy and Gramma Alice stop him and demand an explanation, Cricket tells them of his fear of getting hurt by love, using Gloria as an example (who, having been spurned by Kevin, has dumped her head into the punch bowl). Cricket shows sympathy when he points out her sadness, sounding sad himself at her pain.
Later, after being convinced to try to reach out, despite the potential pain, and being hurt all the same, Gloria and Cricket sit next to each other on the bleachers. After both acknowledge the others sadness with sympathy, Cricket offers for them to dance, Gloria accepts, and, after all the pain the evening has brought, the two finish it happily dancing and smiling at each other, perhaps realizing that the connection of love is not just a romantic one, but also a love between friends.
In "Skunked", Cricket's (admittedly flawed) plan to become a hero (after seeing Mark get a free muffin) backfires on him, trapping him, Gloria and customers inside Big Coffee; realising his mistake, Cricket offers to buy time for the others to escape, even taking one large stinker for Gloria.
When Gloria makes the decision to move out of Big City, Cricket and the Greens help her change her mind. ("Elevator Action".)
These two get along well, and don't seem to mind each other's company (unlike Cricket). Tilly works with Gloria in "Cricket's Shoes" and "Paint Misbehavin'"; in the former she manages to bag Employee of the Month status, one which originally belonged to Gloria; feeling bad for Gloria she decides to sacrifice her status.
Several episodes depict Gloria as being somewhat scared of her boss Ms. Cho, but she deeply respects her and her presence.
Much like her co-worker and friend Cricket, Gloria has taken a disliking to Chip Whistler. In "Coffee Quest" she first encounters him at the docks, in search for a bag of coffee beans. When it becomes apparent that she and Chip are both after the common goal, the bag of beans, Gloria tries to get Chip away from the bag of beans with Cricket's help.
