Tetsudo Hisakawa

久川鉄道, Poppo
Poppo is the first friend that Jinta reconnects with. As a child Poppo was uncontrollably energetic and friendly and was always loyal to Jinta recognizing him as the leader of the group. These traits have not changed. Presently Jinta reunited with him when he was searching for Menma. He visited their old clubhouse and found that Poppo was living there. Poppo explains that he works parttime jobs to earn money. When he makes enough he goes on trips around the world. Because of this Poppo has not attended school in several years. Poppo seems to have questionable interests: Jinta found several pornographic magazines upon entering the clubhouse. Poppo also seems to have an obsession for foreign girls especially Vietnamese girls. Overall he has a lewd personality.
