In 2025, I drew her drinking a glass of Satsuma Mandarin juice and 113 Series, which had been in service on Tokaido Main Line from the 1960s to the 2000s.
113 Series started its regular service in 1964. It adapted to the middle-distance local trains on warm-weather smooth lines, such as Tokaido Main Line, Sanyo Main Line, and Sobu Main Line.
Its orange-and-green-coloured body livery commonly reminded people of Satsuma Mandarin fruit and tree. However, Japan National Railway officially announced that its body livery drew inspiration from that of the Great Northern Railway train in the United States.
113 Series was designed with three passenger doors on each side and a combination of transverse and longitudinal seats to facilitate smooth boarding and alighting during peak morning and evening hours.
Two types of 113 Series on Tokaido Main Line were frequently in service: those belonging to Kozu Railyard and those to Shizuoka Railyard. Kozu carriages mainly operated between Tokyo Station and Shizuoka Station, and Shizuoka carriages mainly operated between Atami Station and Toyohashi Station. Shizuoka ones also sometimes operated to/from Tokyo, coupled with 11-carriage Kozu ones.
113 Series on Tokaido Main Line ended its regular service in 2007.
I had longed to represent Chika and 113 Series because I was emotionally attached to the 113 Series from childhood.
