Irony, the opening to Ore no Imouto ga Konnani Kawaii Wake ga Nai, is a song recorded by the singing duo known as ClariS. This group consists of two high school students named Kurara and Arisu. Uploading their own songs to anime websites led to their debut and signing by Sony Music Entertainment.
Very little is known about the history of these two artists. Any photos are actually anime portraits from a “well-known illustrator.” The mystery surrounding these two–along with the haunting tune shown above–has generated quite a bit of speculation. What I know is that, besides Irony, they have also recorded a song called Connect. It’s the opening theme to Mahō Shōjo Madoka Magica, which starts showing on Japanese TV on January 6, 2011.
There is also a website dedicated to the group: the ClariS Official Website.
Wherever their paths lead them, it is this authors hope that they have an enjoyable and fulfilling career.
