Luka Megurine
Luka was first released on the second Vocaloid platform, had her voice banks edited for an Append, and remade on the third platform. Because of her software her outfit was made to be asymmetrical so she would look different from all angles. She is the only Vocaloid character from Crypton Future Media, Inc. to have her outfit deviate from a school uniform. As all other Vocaloid characters, fans tried to assign her an item. After a debate, her item became a tuna fish, comparing her last name to the Japanese word for fish.
