Background / History

Masumi was introduced as a Class A student who secretly slipped a can of beer into her clothes at a convenience store. Gojo Satoru recorded the act, made her return the item, and ordered her to follow him, leaving her vulnerable to exposure and expulsion. 4

Gojo soon involved her in his challenges against the basketball and tennis clubs, using her Private Point terminal as the stake. The victories raised her balance to 9,072,960 Private Points, but also left her increasingly bewildered by Gojo's unusual abilities and knowledge of the school. 5 6

Within Class A, Masumi initially rejected both the Sakayanagi and Katsuragi factions. She publicly declined Sakayanagi Arisu's tutoring offer, stating that she disliked Sakayanagi and Katsuragi alike; the decision risked isolating her from both groups. 10 11 Despite this, she later accepted Sakayanagi's academic help and studied from materials prepared for her. 19 71

Her feelings for Gojo developed from irritation and fascination into romantic attachment. After seeing him without his blindfold at the cat café, she struggled to hide her attraction; she later confessed with a kiss. 12 13 Their relationship was repeatedly strained by misunderstandings involving Amikura Mako and other girls, but Masumi eventually became one of Gojo's established partners. 24 35 37 110

Masumi initially knew nothing of Gojo's identity as the Monarch or of the Shadow Army. After Hasebe Haruka and the others explained the truth and Igris appeared before her, she accepted it and regretted having spent so much time constrained by Sakayanagi's influence rather than being with Gojo. 113 114 She later visited the restored island, played with the ant soldiers, and eagerly explored Gojo's castle and estate. 118

Appearance

Masumi is a purple-haired girl with delicate features and a notably mature build. She is often described as wearing a sour or intimidating expression, though she becomes visibly flustered around Gojo. 4 12

• Light purple hair 4
• Delicate facial features 4
• Usually wears her school uniform while on campus 4 119
• Frequently adopts a displeased, sharp-eyed expression 4 119
• Blushes easily when Gojo openly teases or shows affection toward her 12 101 110

Personality

Masumi is blunt, proud, and quick to anger, particularly when Gojo gives her orders, ignores her messages, or appears close to other girls. 5 10 11 35 Her jealousy is tied to genuine insecurity: she worries that Gojo may abandon her or value other partners more than her. 24 35 113

She also has a strongly independent streak. Masumi refused to submit to either dominant Class A faction even though she knew she lacked the ability to oppose both alone. 11 She later recognizes the consequences of that isolation and takes her academic work more seriously. 19 24 71

Beneath her harsh manner, Masumi can be empathetic and straightforward. When Kobashi Yume and Shiranami Chihiro asked about Gojo, she honestly clarified that she and Gojo were not dating at the time and helped them locate him rather than misleading them. 24 On the restored island, she also insisted that the ant soldiers should not be harmed during her mock battle, even when Beru assured her they would recover. 118
