Grace

Grace is a fellow operative who shares knowledge of Snow's past, boasting exceptional skills in intelligence gathering and disguise. She originally targeted Snow as a means to elevate her own reputation, but after suffering defeat, she made a pact to stand down. She subsequently infiltrated a high school under the alias 'Nitta', taking on the role of a physical education teacher. Now, as a detached bystander, she watches Snow's new life among ordinary people with great amusement, frequently finding entertainment in the situation and occasionally teasing both Snow and Hito.
