Chibori "Tivoli" Urayasu radiates cheerfulness and optimism, her father’s professional-grade camera perpetually in hand to seize fleeting moments. A chance encounter with Roma Kamogawa during an extracurricular class—sparked by their shared use of single-lens reflex cameras—forges an immediate bond. Before graduation, her family’s relocation to Ireland fractures the group, leaving Roma clinging to a photograph she captured: a sunlit field dotted with a lone ladybug, a silent testament to her absence.

Her departure disrupts the group’s equilibrium, her calming presence sorely missed during chaotic escapades. A misdialed call meant for Tivoli inadvertently bridges the boys to Drop in Iceland, propelling Drop to seek Roma and Toto. This thread unravels further as the group ventures to Iceland, uncovering a telephone booth Drop once visited—now a haunting relic of Tivoli’s intangible influence. The booth and photograph crystallize unresolved ties, echoing her unseen role in steering their paths.

Though physically absent, Tivoli’s imprint lingers, shaping pivotal choices and emotional undercurrents. Her artifacts—the ladybug photo and distant booth—anchor the characters’ intertwined quests for closure, silently bridging gaps between past connections and present journeys.
