Shoko has long brown hair that extends past her shoulders, brown eyebrows, tired eyes, and a mole under her right eye. Shoko has also shown to tie her hair in a ponytail with a light scrunchy.
Shoko wears a white lab coat over a blue shirt and navy blue pants with cream colored high-heels shoes.
As a student, Shoko originally had shoulder length hair, didn't have the tired eyes, and wore a black jacket with a high collar. While testing Gojo's abilities, Shoko wore a long-sleeved black shirt, black shorts, and black shoes.
Shoko is a rather serious and gloomy person, shown to want nothing more to get the job done, and often having to stop or get in between Gojo from poking fun on others. She's shown to be a rather valuable asset, being one of the only people that can heal others with the Reversed Healing Cursed Technique. She is implied to be somewhat of an alcoholic.
When she was a second year, she was rather laid back, in contrast to both Gojo and Geto. She would often try to avoid any escalating conflict as much as she could, and didn't take things seriously, mocking Geto for saying that he wished to create a world with only Shamans in it.
When Shoko was a second-year student at the college, Shoko along with Gojo and Geto go to check up on Mei Mei and Utahime after they haven't heard from them in two days. After making sure that Mei Mei and Utahime are okay and that spirit has been handled, Utahime along with Geto and Gojo meet with Masamichi and were Gojo is punished for not putting up a screen. Later Shoko is with Geto and Gojo, as Gojo and Geto discuss the important use of screens. When Gojo and Geto start to argue about the strong protecting the weak, Shoko quickly runs away.
A year later, Shoko and Geto help out with testing Gojo's technique. After Gojo explains how his new technique works, Shoko says that Gojo will fry his brain if he leave the technique always active but Gojo replies that he has a recovery technique active as well. Sometime later, Shoko has an encounter with Geto in Shinjuku which she calls Gojo for help.
