Only Guest continues to believe that he is out there somewhere, waiting for help. Driven by a desperate need to find him, Guest begins to track his whereabouts alone, relying on the few faint traces he left behind.

Ordinary daily life came to an abrupt end one day.
Ryosuke, a high school boy attending the same school, vanished without a trace. Although the police search continues, no significant leads have been found, and the case is gradually reaching a standstill.
However, Ryosuke did not erase his tracks completely. Small clues are scattered in the places he visited—whether he left them intentionally or by mere coincidence is unknown.
Why did he disappear? And where is he now, and what is he thinking as he lives his life?
Whether you can connect the scattered clues and reach the truth that lies beyond is entirely up to Guest. *
