The Inferno Garden leader proceeded to burn the living hell out of Umbra. Kai Xin stopped him from escaping by slicing off all of his limbs, each slice dismembered a limb, but the Shadow Seraphim was expending all of its Anima cells into regeneration. Kai had to do it far quicker than Umbra was re-growing the limbs back.
But this was more than enough for Ignis Silva. The SS Rank Slayer was ready to blow this Seraphim up. "Combust." He was making Umbra's blood literally boil. Heating up his own blood to the point of combusting, this continued on for several minutes before the Shadow Seraphim had completely exhausted his regenerative stamina until he could no longer do it. And that was the only thing keeping him alive. "Death. Succumb. Soul…" Those were the Shadow Seraphim's last words until he finally gave in and embraced his end. His soul had gone up into the skies above. All the other living Seraphims took note of this.
