The biting wind howled through the Nagano mountains as Inspector Yamato Kansuke pursued his quarry, a shadowy figure known only for his chilling precision. A sudden glint of light, a momentary distraction, and a rifle shot echoed through the desolate peaks. The bullet meant for Kansuke found its mark, grazing his left eye just as an avalanche erupted, swallowing everything in its path. Ten months later, the scars remain both visible and unseen as Kansuke, miraculously alive, is summoned to the Nobeyama National Astronomical Observatory. A researcher has been attacked, and the echoes of that fateful day in the mountains resurface. Conan Edogawa, ever vigilant, senses a connection, a chilling link to a past buried beneath snow and secrets. With Ran Mouri and Kogoro Mouri at his side, the young detective delves into a mystery where every clue is a fragment of a forgotten memory, and the one-eyed flashback threatens to consume them all. Ai Haibara cautions restraint, knowing the darkness they chase may be closer than they realize.
