Kanna is Manabu's mother, who runs a small ramen shop on her home planet. After losing her husband and eldest son in service to the SDF, she naturally didn't take too well to Manabu also enlisting, though she later forgave him. She's generally a supportive mother, though the two of them don't have much contact outside of the occasional visit from Manabu whenever the chance rises. She's a generally levelheaded and independent woman.
