A kid finds his dad's old map to Tokyo's underground and decides to actually follow it. What starts as a treasure hunt becomes something stranger, a descent into a world where forgotten people live in the dark, still fighting wars that ended decades ago.

SYNOPSIS
Ryuuhei stumbles onto his father's old journal while preparing to move. Tucked inside are cryptic clues pointing toward a hidden treasure buried somewhere beneath Tokyo's labyrinth of underground tunnels. What starts as nostalgic curiosity becomes an obsession when he recruits his younger brother, then reaches out to three internet friends willing to chase this half-forgotten mystery. The group descends into Tokyo's underbelly expecting adventure and gold. Instead they encounter a shadow society thriving in the darkness below: underground dwellers, forgotten soldiers still living out wartime fantasies, and people who've chosen to exist outside the world above. Each discovery pulls the teens deeper into a web of secrets, forcing them to question whether the real treasure was ever the kind you could hold in your hands. This adventure film blends coming-of-age innocence with the strange and unsettling. It's part mystery, part character study, and entirely interested in what happens when modern kids collide with the secrets cities keep buried. Expect wonder, discomfort, and the kind of magic that only exists in forgotten places.
