Description
Ream Stream operates as a vital Time Patrol agent, rescuing individuals from historically inconsequential deaths across time periods. Her first meeting with Bon Namihira happens when he accidentally witnesses time travel; following protocol, she initially attempts to erase him. When this fails due to Bon's historical relevance, she recruits him as a Time Patrol apprentice, becoming his primary mentor and mission partner.

Physically, Ream initially stands slightly taller than Bon, though their heights later equalize. The 2024 anime specifies her height as 160 cm, making her 10 cm taller than Bon then. Her design varies: the manga and 2024 anime feature a consistent Time Patrol uniform, while the 1989 anime adaptation uses a distinct uniform influenced by the *Kiteretsu Encyclopedia* art style. The 1989 version also depicts her as shorter than her manga and 2024 counterparts.

Personality-wise, Ream exhibits bravery, wisdom, cheerfulness, and compassion, tempered by firmness and occasional stubbornness. A strong sense of responsibility drives her adherence to Time Patrol regulations, sometimes leading to seemingly harsh actions—like attempting to erase Bon or requiring him to run a fatal marathon in ancient Greece to resolve a paradox. These choices stem from her awareness of historical outcomes and commitment to preventing temporal disruptions. She carries personal burdens from witnessing countless unrescuable tragedies and the disappearance of her own mentor. Adaptations differ: the 1989 anime portrays her as more apologetic, affectionate toward Bon, and willing to break rules to save him (including a life-saving kiss), while the 2024 anime emphasizes rigidity and emotional restraint.

Her skills include agility, stamina, and proficiency with futuristic Time Patrol gadgets, though she occasionally displays clumsiness and errors in judgment. A notable weakness is her inability to swim without specialized equipment.

Relationships are significant. Her dynamic with Bon remains ambiguously romantic due to the manga's cancellation, though they share a close professional bond. The 1989 anime gives her an older brother, Louis Stream, a senior Time Patrol agent she deeply respects; his involvement in the "Leviathan" incident complicates their relationship. Early in her career, she encounters the creature Buyoyon, leading to its recurring interactions with the Time Patrol. While Ream and fellow agent Yumiko Yasukawa never directly interact in the manga, later adaptations and the 2016 film *Doraemon: Nobita and the Birth of Japan* show them working as colleagues.

Notable trivia includes her original name "Stream Ream" in early manga drafts. Her birth year varies: 2002 in the manga, unverified in the 1989 anime, and 2042 in the 2024 anime. Missions in ancient China see her and Bon's interventions in Priest Xuanzang’s journey—using kaiju and kaijin suits—indirectly inspiring the legends of Sun Wukong (Monkey King) and Zhu Bajie (Monk Pig).
