Gekota is a popular mascot found in merchandise marketed to children in the [[Toaru Majutsu no Index]] universe. [[Misaka Mikoto]] is a huge fan of the franchise it belongs to, which - much to her consternation - gets her labeled as childish. Other Gekota fans include [[Hokaze Junko]] and [[Iizumi Rita]].

It's pink version is called [[pyonko]].
