Summary

The chapter opens one year before the EvenStar launch, with Asuka lying in her new bedroom in her mother’s apartment in Yokohama. The apartment is smaller than she expected, and her mother has insisted she take the larger bedroom—a gesture that feels more like a trap, because the smaller bedroom near the front door would have allowed her to slip out unnoticed. After nine years away from home, Asuka feels suffocated by the close quarters and the constant awareness of her mother’s presence.

To reclaim a sense of independence, she escapes into virtual worlds. She transforms her room into a familiar forest of redwood and spruce, and conjures a yellow warbler—a species extinct for thirteen years. The bird’s expression reminds her of Ruth, a connection that underscores how deeply Ruth’s memory still affects her. But the illusion doesn’t hold; the sounds of cicadas and rain from the real world intrude, and she banishes the bird and the forest.

Thirst eventually forces her to leave her room. She hears voices from the living room: two of her mother’s expat friends, Fatima and Weber, are visiting. She checks her news feed and learns that the final eighty-person EvenStar crew has arrived in Okinawa for training at a former U.S. military base. The news stirs a mix of dread and longing—she is adrift and alone while the crew she once belonged to moves forward without her.

She decides to get a glass of water, but the rain picks up, and she reluctantly joins the conversation. Weber greets her with a condescending “Asuka-chan,” which she resents. The adults ask about her EvenStar experience, particularly the memorized strings of numbers that Professor Tod once made them learn. Asuka explains that the numbers were randomly generated and meaningless, but the adults exchange significant glances, hinting that they suspect otherwise. They also bring up the restrictions on posting political content, and Asuka recalls how Lala was removed from the U.S. team, though she later earned a Wild Card spot.

Weber then mentions a striking coincidence: the night Linda first launched DAR, a supernova appeared in the sky. Asuka dismisses the implication as absurd, but the story is one Linda herself likes to tell. The conversation turns to Asuka’s future. Fatima asks what she plans to do now that she’s “free,” and Weber jokes that life on Earth is hard. Her mother suggests she become an ornithologist, a childhood dream Asuka had long outgrown. Asuka is furious—she feels her mother is reducing her to a nine-year-old’s fantasy. The room seems to recede, and she feels utterly lost, unsure of who she is in this world. She grabs a cup of tea and gulps it down, desperate to feel something real.

Key Events

  • Asuka lies in her new bedroom in her mother’s Yokohama apartment, feeling confined after nine years away.

  • She uses virtual reality to escape, conjuring a forest and an extinct yellow warbler that reminds her of Ruth.

  • She checks her news feed and learns the EvenStar final crew of eighty has arrived in Okinawa for training.

  • She joins her mother’s friends Fatima and Weber in the living room, where they question her about EvenStar.

  • The adults press her about memorized number strings and posting restrictions, hinting at hidden meanings.

  • Weber mentions the supernova that appeared the night Linda first launched DAR.

  • Her mother suggests she become an ornithologist, a childhood dream, which sparks Asuka’s anger.

  • Asuka feels disconnected from reality and gulps down tea to ground herself.

Character Development

This chapter deepens our understanding of Asuka’s internal state in the year before launch. She is caught between two worlds: the structured, purpose-driven life of an EvenStar trainee and the mundane, confining reality of her mother’s home. Her use of virtual reality as an escape highlights her alienation from the physical world and her longing for the familiar—even if that familiarity is a constructed forest or a memory of Ruth. The yellow warbler, extinct for thirteen years, symbolizes loss and the impossibility of returning to what once was.

Asuka’s interactions with her mother’s friends reveal her discomfort with being treated as a child. She resents the diminutive “-chan” suffix and the way the adults speak about her as if she isn’t in the room. Her irritation at her mother’s suggestion of ornithology is not just about the career itself but about being reduced to a childhood fantasy—a sign that her mother doesn’t see the adult she has become. Asuka’s feeling of being “shrunk to the size of a small figurine” captures her loss of agency and identity.

The chapter also shows Asuka’s lingering connection to EvenStar. She is aware of the crew’s arrival in Okinawa and feels a mix of dread and longing. Her memory of Lala’s removal and the paranoia it caused among the trainees suggests that EvenStar’s control extended beyond the physical—it shaped how they thought and behaved. Asuka’s internal conflict—wanting to be free yet feeling adrift without the structure EvenStar provided—is a central tension.

Themes, Symbols, or Motifs

  • Virtual reality as escape: Asuka uses VR to retreat from her uncomfortable reality, but the escape is temporary and unsatisfying. The forest and the warbler are illusions that cannot shield her from the cicadas and rain.

  • Extinction and loss: The yellow warbler, extinct for thirteen years, mirrors Asuka’s own sense of being a relic—someone who no longer fits into the world she has returned to. It also connects to Ruth, whose memory is tied to loss.

  • Institutional control: The memorized number strings and the restrictions on posting reveal EvenStar’s pervasive influence over its trainees. Even after leaving, Asuka is haunted by the paranoia and the need to maintain a “clean image.”

  • Childhood dreams vs. adulthood: Her mother’s suggestion of ornithology represents a static, idealized version of Asuka’s past self. Asuka’s anger shows her desire to be seen as a changed, complex adult, not a child with simple passions.

  • Disconnection from reality: Asuka’s urge to touch objects to confirm they are real underscores her profound sense of unreality. She feels like a vessel, empty and adrift.

Why This Chapter Matters

This chapter provides crucial backstory for Asuka’s emotional state leading into the main events of the novel. It explains her deep-seated feelings of alienation and her struggle to define herself outside of EvenStar. The flashback also introduces key details—the memorized numbers, the supernova coincidence, and Lala’s removal—that may have larger implications for the plot. Asuka’s relationship with her mother is established as a source of tension, and her unresolved grief over Ruth is subtly reinforced through the warbler imagery. This chapter grounds Asuka’s motivations and sets the stage for the choices she will make later.

Study Questions and Answers

  1. Why does Asuka react so strongly to her mother’s suggestion that she become an ornithologist?

Asuka’s reaction stems from her feeling that her mother is reducing her to a childhood fantasy. The suggestion implies that Asuka hasn’t grown or changed, and it dismisses the complex adult she has become. It also highlights the disconnect between her mother’s perception of her and her own sense of identity, which is already fragile after leaving EvenStar.

  1. What does the yellow warbler symbolize in this chapter?

The yellow warbler, extinct for thirteen years, symbolizes loss and the impossibility of returning to the past. It also connects to Ruth, as its expression reminds Asuka of her. The bird represents Asuka’s own feeling of being out of place in a world that has moved on without her, and her longing for something that can never be recovered.

  1. How does the conversation with Fatima and Weber reveal EvenStar’s control over Asuka?

The adults’ questions about memorized numbers and posting restrictions show that EvenStar’s influence extends beyond training. Asuka’s memory of Lala’s removal and the resulting paranoia demonstrates how the institution shaped her behavior and thinking. Even after leaving, Asuka is still bound by the habits and fears instilled by EvenStar, illustrating the lasting impact of institutional control.
