Ghost of Ueno.

In 2023, over 80,000 people went missing in Japan, with 30,000 dying alone. Ten percent remained unidentified, known as “muenbotoke” (buddhas without connections). Satsuki works part-time at an NGO near Ueno Park, indifferent to her job and the faces of those seeking help, until she stumbles upon the diary of a deceased homeless man. Toshi, a fellow drifter in the park, tells her that her encounter with the man’s ghost is no accident. Guided by the diary, they embark on a journey into the past to uncover the man’s identity, which is deeply intertwined with Ueno’s post-war history. Along the way, they meet those whose lives the ghost touched, each revealing a story of a man who willingly cut ties with his family. Satsuki’s dreams and memories lead her astray, uncovering a bitter truth. Her search for answers about the vanished finds resolution in Toshi, who waits for the third reincarnation of his late wife.
