Tetsuko "Alice" Arisugawa, a 14-year-old adjusting to life in Fujiko with her divorced mother, navigates adolescent uncertainties with quiet resilience. Her reserved exterior masks a sharp curiosity sparked by discovering old academic tests in her new bedroom—left behind by Kotaro Yuda, a name entwined in schoolyard whispers of a Judas-linked murder. Defying classmates’ superstitions, her impulsive streak drives her to probe the rumors, pushing past social ostracization.

Though initially awkward, Alice’s carefree boldness draws her to Hana Arai, a guilt-ridden neighbor avoiding school over Kotaro’s past. Their alliance begins as pragmatic sleuthing but deepens as Alice’s persistence chips at Hana’s isolation. Alice deciphers clues with methodical precision, linking "Yuda" to Judas lore and tracing Kotaro’s fate. A botched confrontation with Kotaro’s father spirals into chaos, yet culminates in Hana confessing her role in his accidental bee-sting ordeal—revealing the truth behind the gossip.

Petite and sharp-eyed, Alice’s short black hair and green gaze mirror her tidy school uniform. Her ever-present notebook anchors her sleuthing, while a ballet-trained grace surfaces in fluid movements captured through rotoscoping. The investigation becomes a crucible: her tenacity not only clears Kotaro’s name but coaxes Hana back to school, mending fractured bonds.

Through navigating her mother’s divorce, Fujiko’s social labyrinths, and fragile new friendships, Alice evolves from a wary outsider to a bridge for Hana’s redemption. Her journey—stitched with observation, loyalty, and unyielding curiosity—highlights how truths uncovered can heal hidden wounds.
