Hina Yumihara (弓原 雛, Yumihara Hina), is the main heroine of the Buddy Complex anime. She is introduced as a highly skilled Ensign-ranked Valiancer pilot, making her an integral part of the Free Pact Alliance’s forces. At the beginning of the series, Hina is revealed to be Aoba Watase’s classmate, though her true origins are far from ordinary. Hina, it turns out, comes from the future, having been sent back in time to protect Aoba from a dangerous threat looming over him and the world.
In the future, in the year 2088, Hina assumes a new identity as Hina Ryazan, a Valiancer pilot serving the Zogilia Republic. This dual identity as both a student at Seio High School and a key military figure creates a complex and multifaceted character arc, as Hina struggles with her responsibilities in both timelines while also growing emotionally and developing deep bonds, particularly with Aoba. Her mysterious background and commitment to her mission make her a central and pivotal character in the series.
Background

Appearance in Anime
Hina Yumihara’s backstory is marked by the unique and secretive nature of her mission. Initially introduced as a student at Seio High School, Hina becomes close to Aoba Watase, though she conceals the true reason for her presence in his life. Unbeknownst to Aoba, Hina comes from a war-torn future, where she is a skilled Valiancer pilot enlisted to protect him from a critical threat that would shape the future.
In the year 2088, Hina is revealed to be Hina Ryazan, a soldier in the Zogilia Republic’s military forces. She operates as a Valiancer pilot and is embroiled in the ongoing war that threatens to change the course of history. Hina’s dual identity as both a high school student and a soldier from the future makes her a key figure in the overarching narrative, as she works to ensure Aoba’s survival while also participating in the intense battles of the Hand Shaker war.
Her emotional and psychological growth throughout the series is shaped by the heavy burden of her mission, her growing bond with Aoba, and her internal conflict between the duties of a soldier and the desires of a young woman falling in love.
Appearance
Hina Yumihara has a distinctive appearance that reflects her dual nature as both a student and a soldier. She has long, dark hair that is often styled in a simple, elegant way, and her facial features are delicate yet determined. Her sharp, intelligent eyes convey both strength and vulnerability, mirroring the internal conflict she faces as a protector and a young woman caught between two worlds.
When in her Valiancer pilot uniform, Hina’s appearance takes on a more militaristic look, with her attire reflecting her role as a soldier in the Zogilia Republic. Despite the seriousness of her mission, her personal style outside of combat is modest and approachable, and her appearance at school is youthful and understated, which contrasts with her more intense and battle-ready persona as Hina Ryazan.
Personality
Hina Yumihara is a strong, determined, and intelligent character with a deep sense of duty and responsibility. Her personality is shaped by the weight of her mission, and she often puts the well-being of others before her own desires. This sense of duty makes her a reliable and capable individual, both as a student and as a Valiancer pilot.
Though Hina is initially reserved and distant due to her secretive nature, her interactions with Aoba Watase reveal her more compassionate and vulnerable side. As the series progresses, Hina becomes more emotionally open, particularly in her relationship with Aoba, which forces her to confront her own emotions and the growing complexities of her role in both timelines.
Hina is also highly self-aware and often struggles with the tension between her duty to protect the future and her growing attachment to the people she interacts with. Her inner conflict between duty and personal desire forms a central aspect of her character arc.
Role in the Story
Time-Travel Guardian: Hina’s first role is that of Aoba’s protector, secretly assigned to shield him from the Valvrave attack by future enemies. When their cover is blown, she transports Aoba into the future to save his life, at the cost of becoming stranded in her own time.
Identity as Hina Ryazan: In the year 2088, she is revealed to be serving the Zogilia military as a Valiancer pilot. Due to memory distortion from time travel, she no longer recognizes Aoba. Their fateful re-encounter in the heat of battle sets off a chain of emotional and plot-driving events.
Reconnection and Emotional Struggle: As the series continues, Hina begins to regain her memories of Aoba, creating emotional turmoil as her feelings conflict with her loyalty to Zogilia. Her eventual change of heart and actions become a turning point in the war and the time paradox surrounding Aoba’s survival.
Relationships
Aoba Watase: The protagonist and the boy she is destined to protect. Hina’s bond with Aoba transcends time, and their interactions drive the emotional heart of the story. Despite moments of conflict and confusion, she eventually remembers her past feelings and supports him in the climactic moments of the war.
Zogilia Republic: Initially loyal to Zogilia, Hina’s affiliation begins to waver as she reconnects with her past self and memories. Her inner conflict between duty and conscience becomes a central theme in her arc.
