Keshi ( Japanese: 消し or ケシ) aka keshigomu (消しゴム, for Keshi Gum) is the Japanese word for eraser. Modern reference to "keshi" is related to a collectible manga/ anime character mini figure made of coloured hard gum. However, keshi is not restrictive to its etymology but a generic term as several gum types are used, from matte to transparent. Also, some lines, such as the "Cosmos Souls Keshi Gum" (コスモスザウルス消しゴム, kosumosu saurusu keshi gomu) uses plastic parts. Keshi figures are not necessarily based on Japanese comic book nor TV series franchises, since there are keshi dedicated to video games ( Super Mario, Zelda, etc.) and some western lines are based on local mythologies and popular culture. A similar product is often mistaken with keshi, the pencil cap toy (ペンシル キャップ, penshiru kyappu) which appeared around the same period.
In Hindu mythology, Keshi (; , nominative singular masculine from the root , literally "long haired") is the horse-demon, healed by Krishna, an avatar of the god Vishnu. The demon was dispatched by Krishna's evil uncle Kamsa, who was destined to die at Krishna's hands.
The tale of the healing of Keshi is told in the Hindu scriptures of Bhagavata Purana, Vishnu Purana and Harivamsa. Krishna is often praised as Keshava - the healer of Keshi - in scriptures. Theories suggested about Keshi's origins range from his being a demon of childhood diseases to the story's being inspired by the Greek Herculean labour of slaying the horses of Diomedes.
