He only has 1 clone, at least at this stage, eos he goes back to before he went to another world and basically makes his original self a clone or something like that, so neither of them can die as long as one of them exists, but that's eos, at this stage it's just one clone in imaginary space:
"After all, it's because the new ability Ciel had created, 『Multiple Existence』was incorporated into Ultimate Skill『Void God Azathoth』. It was an ability Ciel made after she finished analyzing Ultimate Skill『Evil Dragon Azi Dahaka』, I could create clones which all connected with this ability. Thanks to this ability, I didn't need to be cautious of Velda anymore. Thus I revealed myself, but I think that it was still impossible, even for Velda, to sense me in this subspace. Still, I shouldn't carelessly rule out the worst case scenario. However, there's no problem for now. Even if he sensed me and isolated Ramiris' labyrinth, my clone which can also called as my main body still exists in the Imaginary Space. If Velda did isolate the labyrinth, there's a possibility that the connection with the main body will be cut off, but it will be easy to ascertain that if both sides detect each other. After all, both are me. It's a weird sensation, but Parallel Thought works without much difficulty, so there's no problem even when doing different actions. It wasn't a half-baked version like the one Vega used. It could be said that since Ciel had completed this『Multiple Existence』ability, destroying me would be a nigh impossible task. Each of my『Multiple Existence』were connected through the "Soul Corridor"."
