Rin Shin is a studio staff artist and animator who was employed by the ARMS Corporation. Rin has a reputation as a designer for ecchi anime, such as Ikki Tousen and To-Love-Ru. Rin Shin draws lots of so-called adult anime characters in the beginning but since the business in this genre of ARMS had downward trend from the business view points, Rin also started to write "normal" animation/characters, when ARMS changed its company policy in that way. In the case of Elfen Lied, Rin Shin designed the key animation for the memorable opening and closing credits of the anime series, using the paintings of Gustav Klimt as the basis. The gender, age and real name of the artist is unknown. Rin currently runs RIN-SIN ILLUSTRATIONS.
