Mobyama Aji to Mobtani Crou no Kareinaru Nichijou e no Chousen

Is there a way to escape the life of a background character? Mobuyama "Eiji" A-Ji and Mobuyama "Shiro" C-ro have lived their entire lives as nothing more than "extras" to other people's stories.It can't end like this , right? There must be a way out! Both sharing a common goal will try anything that allows them to change their destiny, ANYTHING.
