Description
Mari Kusakabe is a 32-year-old motorcycle courier who becomes an indispensable protector and guide for the two young siblings Mirai and Yuuki Onozawa after a catastrophic magnitude 8.0 earthquake strikes Tokyo. She lives with her young daughter Hina, who turns four years old on the day of the disaster, and her mother (or, in some accounts, her mother-in-law). A single mother who lost her husband some time before the events of the story, Mari works as a quick-service driver for the delivery company Tiger Express, a job that gives her familiarity with the city’s streets and a practical, resourceful demeanor.
Mari’s personality is marked by a deep, instinctual compassion and a strong sense of responsibility toward others in need. When she first encounters Mirai searching desperately for her younger brother in the immediate aftermath of the quake, she offers help without hesitation. Asked later why she is willing to assist two strangers, she replies simply, “because I'm a human.” This line encapsulates her core motivation: she sees the suffering of others as something she cannot ignore, and she acts on that empathy even when her own heart is heavy with worry for her daughter and mother. Mari carries an underlying anxiety about her family’s safety, which she largely keeps in check to remain a steady, calming presence for the children. She is described as having a personality that cannot leave people in need, and she actively supports and leads Mirai and Yuuki through the dangerous, ruined city.
Her role in the story is that of a guardian and surrogate maternal figure. She and the siblings make a mutual promise to reach their respective homes together—Mari to Sangenjaya, where her daughter and mother are waiting, and the children to Setagaya to reunite with their parents. Throughout their journey, she provides not only emotional stability but also practical survival skills, navigating collapsed roads, fires, aftershocks, and the chaos of the disaster zone. Her experience as a motorcycle rider and her familiarity with the city’s layout are assets. At the same time, she wrestles with the internal conflict of needing to care for two vulnerable children while being desperate to know the fate of her own family. This tension drives much of her character arc.
Mari’s key relationships are with Mirai and Yuuki. She becomes a trusted protector for the younger brother, Yuuki, who looks up to her as a maternal figure, and a mentor for the often cynical and frustrated Mirai, who gradually matures under Mari’s steady guidance. The three form a makeshift family unit during the crisis, and Mari’s own toughness—which she admits to having developed after her husband’s death—rubs off on Mirai, helping the girl grow from a self-absorbed teenager into a more selfless and resilient person. Mari’s relationship with her own daughter, Hina, and her mother is the emotional anchor that keeps her moving forward, even when the journey seems impossible.
In terms of development, Mari begins as a capable but internally torn adult who is already hardened by personal loss. Over the course of the series, she demonstrates remarkable endurance and selflessness, putting the children’s safety on equal footing with her own desperate need to find Hina. Her struggle to balance these two priorities shows her depth as a character, and by the end she has reaffirmed her commitment to protecting those around her, even at great personal cost.
Notable abilities include her skill as a motorcycle courier, which gives her strong navigational knowledge of Tokyo and the ability to maneuver through debris and blocked roads. She also possesses a level-headedness and decisiveness in crisis situations, as well as the physical stamina to keep moving through the devastated city. Her most defining trait, however, is her moral clarity: she acts directly to help others because she believes it is the right thing to do.
