Description
Natsuna Keyaki, a post-secondary student from Tokyo, forms a deep online friendship with Itsuki Kusunoki on a game platform reminiscent of Animal Crossing. They bond through shared virtual activities, particularly drawing, making this connection her primary social relationship. When the 2016 Kumamoto earthquakes disrupt communication, Natsuna ceases contact. She later rationalizes abandoning Itsuki by claiming preoccupation with school, despite knowing the disaster impacted Itsuki's region.

Four years after losing contact, Itsuki briefly reaches out via their old gaming platform. Their exchange is abruptly severed when the service shuts down mid-communication. Fueled by lingering guilt over her previous neglect and a newfound sense of responsibility, Natsuna travels alone from Tokyo to Kumamoto Prefecture. She possesses minimal information—only Itsuki's name and a landscape drawing Itsuki created—yet her journey reflects underlying determination, contrasting her self-perception of limited social connections.

In Kumamoto, Natsuna navigates unfamiliar rural environments and interacts with locals, demonstrating unexpected adaptability. Her search leads her to Constable Masayoshi Maezono for help. She later forms an impromptu partnership with Izumi Chiba, an outgoing middle school student who provides shelter and actively supports the investigation. Staying with Izumi's family, Natsuna experiences Kumamoto's community culture through communal meals and local festivals. This exposure gradually shifts her focus from a solitary mission towards appreciating human connections.

Throughout her journey, Natsuna confronts memories of her neglected friendship. This culminates in emotional distress upon discovering Itsuki's family home destroyed and learning how the earthquakes traumatized Itsuki. These revelations trigger intense guilt, manifesting as nightmares and public emotional outbursts. Her persistence eventually leads her to Sakitsu. There, she meets Haru Kusunoki (Itsuki's grandmother) and encounters a gray-haired girl drawing landscapes. The girl initially denies being Itsuki. Accepting this denial temporarily, Natsuna prepares to leave Kumamoto. However, at Kumamoto Airport, she realizes the deception and abandons her return flight to confront the girl directly.

In their climactic reunion, Natsuna rejects superficial explanations and insists on affirming their friendship in person. She learns Itsuki sustained a hand injury during the earthquakes, halting her artistic pursuits until her recovery in Sakitsu. Itsuki had interpreted the lapsed communication as hatred. Natsuna's heartfelt apology and reassurance mend their relationship, allowing them to fulfill their old promise to draw Kumamoto's landscapes together. This journey facilitates Natsuna's maturation, moving her from isolation towards valuing tangible human bonds and understanding community resilience in post-disaster recovery.
