Nijigahara Holograph

虹ヶ原ホログラフ

Arie Kimura is a pale, long-haired fifth-grader who unsettles her classmates with a fairy tale about a monster said to live in the Nijigahara tunnel. Convinced she must be sacrificed to the creature, seven of them push her down a well and pass it off to the adults as an accident, leaving Arie comatose. The narrative then splits across two timelines eleven years apart, tracing how those children grew up and how the dread of the prophesied monster — heralded by swarms of butterflies — keeps surfacing.
