Code was among those Jigen and Amado experimented on in order to find a suitable vessel for Isshiki Ootsutsuki. Code proved to be an unsuitable receptacle for Isshiki's soul but survived the ordeal, attaining a White Karma. Code came to worship Isshiki as a god and was inducted into Kara as an Inner, with Amado enhancing his body with Scientific Ninja Tools.
