Hmm i wonder if that residual is even usable more like are there even any left, Samael's curse destroyed Ise's original body after all. It wouldn't make sense to create a Dragon clone that is cursed and will die immediately. Plus we don't even know how Euclid savage the so-called residue. If Euclid only took the portion that somehow avoided the curse to make his Boosted Gear Replica and use it up entirely on it, then there would be none left.

Either way, i don't think it's a good idea for there to be Ise clones.
