Mito is a grown woman with fair skin, hazel eyes and orange, shoulder-length hair. She wears a red, long-sleeved blouse that partly exposes her collarbones over a long cream-colored dress. For accessories, she wears brown shoes and an Aegean, circular necklace.
Mito is Gon's mother figure, as she has taken care of him since he was a baby. Gon stated that when he tries to picture his mother, Mito's image shows up. At first, she was against the idea of Gon following his father's footsteps by becoming a Hunter as well, but she accepts this later on. She is motherly, kind and patient, being able to put up with Gon's faults and tends to him very well. Mito also tends to get easily embarrassed, namely when Abe told Gon about when Mito was always lost when she was young.
She believes that people shouldn't take others lives, such as when she slapped Killua when he tried to kill a foxbear cub. She is also a great cook.
Mito and Ging Freecss used to be very close when they were children. She often got lost and only Ging seemed to be able to find her, to the point that the inhabitants of Whale Island started to gossip that she did it on purpose, although she does not seem to remember this. When Ging left to become a Hunter, she was very upset and told him not to return.
Mito has had the guardianship of Gon since he was an infant. At first she told Gon that his parents died in an accident soon after his birth but eventually reveals that his mother is unknown and his father, Ging Freecss, is a Hunter who left Gon in her care. Originally, Ging returned to his home on Whale Island to ask his grandmother to babysit Gon for him. Specifically, Mito fought Ging for custody of his infant son because she believed he was irresponsible. He has never returned.

Eventually, she makes the promise that should Gon catch the giant fish known as the Master of the Swamp, she will sign Gon's application to take the Hunter Exam. However, she only makes this promise because she believes the task is impossible, even giving Gon his father's fishing rod for the job. A couple of days before the Hunter Exam, Gon manages to catch the Master of the Swamp much to Mito and everyone in Whale Island's Harbor area. Mito hesitates to sign the application form that would allow Gon to partake in the Hunter Exam, even though Gon insists she does.
Frustrated and reluctant to sign the application, she finally gives in after Gon reminds her about how she taught him about keeping promises. Back in their house, as Gon heads out to mail his Hunter Application, Mito argues with her grandmother on how Gon figured out the truth about his father. Gon subconsciously apologizes to Mito, claiming he's known about the truth for a long time. That night in their dining room, Mito discusses with Gon how why he'd want to pursue being a Hunter when his father abandoned him so he could continue being a Hunter. Gon's response though baffles Mito as he thinks being a Hunter must be incredible profession. Agitated Mito leaves Gon and claims he truly is his father's son.
On the day of Gon's departure, everyone on Whale Island give their farewells to Gon, he approaches Mito who stands by the harbor. Gon thanks Mito for all that's she's done for him and Mito apologizes to Gon admitting she lied to him that his father abandoned him and confesses he took him from his father by the court.

Gon replies a month or so, she asks him if he plans on finding his father, to which Gon replies yes.

Mito's Grandmother explains that Ging wanted wanted them to watch over Gon in his absence and when inquired about his Mother he informs them that they're separated from one another.

He goes onto say that they talked for a long time about various stories they had and was elated by the experience he had with him. Gon though admits Ging was more like an amazing relative he heard about than a father. Finishing off a clam, Mito claims that has absolutely no qualities, skill, or experience to be a father and adds he doesn't have any motivation or self-awareness what-so-ever.
Gon then brings up the point that he shares some of those same traits for he has no qualities as a son. Flustered Mito and makes apologizes for her actions, claiming Ging is a scumbag. Gon confesses he never thought of being with Ging just because he's his father, but for rehashes that if he was still Nen capable he'd feel Ging's strength and "awesomeness" then he'd want to follow him.
