Strawberry Marshmallow (苺ましまろ, Ichigo Mashimaro) is a Japanese manga series by manga creator Barasui about the adventures of four elementary school girls and their older sister-figure. It was created by Barasui for the manga magazine Dengeki Daioh in 2002. In 2005, the series was adapted into an anime series and a PlayStation 2 video game. Three original video animation episodes were later released from February to April 2007. Another OVA project was announced in 2008 called Strawberry Marshmallow Encore and released in 2009.
Strawberry Marshmallow is set in Hamamatsu, Japan. Seasons play an important role throughout Strawberry Marshmallow as the characters are involved in many normal seasonal activities. The series is speckled with many small, music-related allusions, such as Ana's dog Frusciante being named after John Frusciante of the Red Hot Chili Peppers, while episode eight of the anime sees two goldfish called Richard and James. The title itself was inspired from "Mashimaro", a single by Japanese rock artist Tamio Okuda.
