Mafuyu Oribe is one of the main heroines, known for her resilience, solid swordsmanship, and her role as a protector despite her own insecurities, as she navigates the dangerous world of St. Mihailov Academy alongside friends and rivals.
Her measurements are B80/W56/H84, placing her in the "standard" range for her age.
Mafuyu has an athletic build, shaped from her time as a Kendo club member.
Despite being of average chest size, she feels a bit insecure since those around her—like Tomo Yamanobe—are notably more well-endowed.
Her appearance gives off a reliable and approachable aura.
Mafuyu is responsible, courageous, and exceptionally quick-witted.
She’s fiercely protective of Tomo Yamanobe, often rushing to her aid and facing any adversity head-on.
Although she has a bit of a complex about not being as voluptuous as others, she handles it with quiet strength (and the occasional witty retort).
She often finds herself exasperated by Alexander Nikolaevich Hell’s outrageous, shameless antics—but her sharp tongue and strong spirit make her a perfect foil.
Mafuyu is also gentle and nurturing, with a knack for cooking; her borscht especially impresses Alexander.
Mafuyu was once a member of the Kendo club, honing her skills with the bamboo sword.
She is an orphan, taken in and raised by Yuu Yamanobe, the former chairman of St. Mihailov Academy, alongside his only daughter, Tomo Yamanobe.
After Yuu Yamanobe’s mysterious disappearance, Mafuyu took it upon herself to protect Tomo from the hostile treatment she began receiving.
Her sense of responsibility toward Tomo grew into a deep bond more akin to that of sisters.
Mafuyu possesses solid Kendo skills, often using a bamboo sword to protect others.
She later becomes the host of the “Holy Sword Maiden,” an esteemed relic divided between her and Tomo after major battles.
Due to this, she becomes a primary target for adversaries seeking the relic’s power.
Under the training of Big Mam, she gradually learns to wield the Holy Sword Maiden’s abilities in combat.
Her control is limited but steadily grows as she fights alongside Alexander and others.
Tomo Yamanobe is like a younger sister to Mafuyu, with Mafuyu taking a guardian's role.
Alexander Nikolaevich Hell, though their relationship starts off rocky and combative, eventually becomes an important ally—and someone for whom Mafuyu develops feelings.
Their progress is slow and innocent compared to more experienced pairs like Fool and Mutsumi Sendou.
She also works closely with Aoi Kuchiba following the fall of the Garden, sharing responsibility in the pursuit of truth.
Her relationship with other main characters is strengthened by shared battles and mutual respect.
Mafuyu’s chest size is a recurring comedic point, as she finds herself surrounded by friends with larger busts.
Her cooking—especially her borscht—gains universal praise.
Despite several run-ins with mischief or embarrassment (often thanks to Alexander), she’s reliably the “straight man,” providing sanity in chaotic situations.
Her Kendo skills have saved fellow students—and even Alexander—multiple times.
“I won’t let anyone harm Tomo!”
“Why do you always have to be so shameless?!”
“If there’s something I can do, I’ll do it—no matter how scared I am.”
Early Days at St. Mihailov Academy
Mafuyu is introduced as Tomo’s loyal friend and protector.
With Tomo being targeted after Yuu Yamanobe’s disappearance, Mafuyu struggles with increasing harassment from others—pushing herself to be even stronger.
Meeting Alexander Nikolaevich Hell and Involvement in Battles
Her initial relationship with Alexander Nikolaevich Hell is antagonistic, as she often confronts his odd and embarrassing behavior.
Despite this, Mafuyu’s bravery and quick thinking save him multiple times, leading to a growing trust.
She eventually becomes Alexander’s “Maria,” forming a partnership that fuels their mutual growth.
Becoming the Holy Sword Maiden’s Host
After intense battles with Phenix and the Golden Qwaser, the Holy Sword Maiden’s power divides between Mafuyu and Tomo.
From here on, Mafuyu is constantly pursued by powerful enemies determined to seize this relic.
Alliance and Loss
Choosing not to remain a bystander, Mafuyu resolves to fight alongside Alexander and undergoes strict training with Big Mam to harness the Holy Sword Maiden’s power.
When her heart is cursed by Athos’s magical circuit, she survives thanks to Agatha’s compassion.
She does not participate in the climactic battle at the Garden, but teams up with Aoi Kuchiba and Alexander afterward, unraveling the secrets behind the Divine Creation Plan and the Golden Usurper.
After a tearful farewell to Urara Oikawa, she returns to St. Mihailov Academy.
