Nagashima

A mysterious old man who haunts the town where the story takes place, wearing only underwear and a military helmet. After being hit by a hit-and-run driver, Papico tries to save him, but he stops her from calling an ambulance and implants a machine in her right wrist, giving her the future power to transform into a giant. Following this act, he turns into a small doll.

His true identity is that of a senior military officer from the future with the rank of Colonel. He was the first member of his team to travel to the past with the mission to save Dr. Banner and prevent the AI uprising. Upon his arrival in the 21st century, he felt a curiosity for vending machines and found the clothing of modern people to be strange. During his time in this era, his journey was recorded for 168 hours; this DVD is eventually found by Papiko at the moment of his death.
