The affiliation of Vocaloid characters with certain items has its roots with 'Item Wars' (持ち物戦争, mochimono sensou) that occurred between fans online. This is often a source of confusion for many people who are unfamiliar with Vocaloid characters as the relevance of these items is not immediately obvious. Vocaloid characters are often depicted with a particular item, for example Hatsune Miku is often pictured as holding a leek and Kagamine Rin a mikan orange.
