Background & History

Morishita is the only daughter of the head of Morishita International Company, a Fortune Global 500 firm involved in virtual stealth technology, large-scale game development, machine exoskeleton research, and industrial design. Her family’s company later develops Yu-Gi-Oh! virtual-projection technology and holds a monopoly on virtual helmets in Japan. 41 147 896

At school, she serves as one of Sakayanagi Arisu’s assistants alongside Kamuro Masumi. Although she initially works closely with Sakayanagi, she is easily drawn to Akasaka after discovering that they share anime, manga, and gaming interests. 15 20 After admitting that she is interested in him, she agrees to become Sakayanagi’s “left and right arm.” 42

Morishita’s relationship with Akasaka develops through their shared chuunibyou behavior and Yu-Gi-Oh! duels. Following a duel, she treats their prior agreement as meaning that she now belongs with him, establishing herself as his girlfriend. 60 She later declares herself the “boss” of Akasaka’s partners and sets rules governing their hierarchy and intimacy while they remain in school. 243

Her position is repeatedly challenged by Akasaka’s expanding relationships. She keeps Kato Megumi under close watch, including using handcuffs and chains to prevent her from secretly visiting Akasaka. 262 328 476 Despite her possessiveness, Morishita is capable of compromise when Akasaka’s condition is at stake; after fighting Shiina Mahiru, she proposes a temporary reconciliation so they will not disturb him while he is hospitalized. 806 809

After learning of Akasaka’s relationships with Yuki and Mizuhara Chizuru, Morishita temporarily withdraws from school. Before leaving, she transfers nearly 220 million Personal Points to Sakayanagi and instructs her to spend 20 million points to bring both Morishita and Akasaka back later. 376 377

In a future side story set ten years later, Morishita is married to Akasaka and has a daughter, Morishita Rin. She supports Akasaka’s continued Yu-Gi-Oh! obsession, while also caring for some of his other children despite her resentment over his many relationships. 147

Personality

Morishita outwardly resembles a quiet, emotionless Three-No Girl, but she is an enthusiastic chuunibyou and devoted otaku. She readily performs anime references, adopts fictional personas, and becomes excited when someone understands her jokes. Her compatibility with Akasaka stems largely from their mutual enthusiasm for such behavior. 20 569

She is affectionate and openly jealous where Akasaka is concerned. Morishita reacts strongly to perceived romantic rivals, confronting Sakayanagi over rumors, fighting Mahiru, and attempting to preserve her authority among Akasaka’s partners. 241 806 929 She can nevertheless be practical and diplomatic when necessary, particularly when defending her family’s interests or maintaining order among the group. 334 809

Morishita is physically unfit and recognizes that she cannot safely overpower stronger opponents. Her restraint against the pregnant Mahiru leaves her at a disadvantage during their fight, and Asuna later defeats her with a single punch. 806 809 929
