Ep. 13: College student and Kido recall a childhood hide-and-seek game where Kido was left behind.

13

A college boy and his childhood friend Kido reminisce about a hide-and-seek game wherein Kido was abandoned while hiding. Owing to the late hour, he invites Kido to stay over. The next morning, the room has been ransacked; Kido tells him that he did it in his sleep, searching for something, but wouldn't say what. The young man abruptly leaves for work. Upon returning, he decides to set up a camera. He wakes up in the middle of the night, and the room is a mess. He checks the footage - he was searching the room in his sleep. A pile of papers and an old photo fell to the floor, and Kido's voice asked what he was looking for. Still asleep, the young man said he was looking for Kido, who replied that it's no longer necessary. The young man looks at the old photo, which is of himself, Kido, and another friend as kids; Kido is slowly vanishing. Kido's voice tells him not to worry, as someone will search for him next. The photo falls to the floor; both he and Kido have vanished. (Source: Wikipedia)
