Even with everyone's Cosmo fused together, Seiya and Ikki's battle was still extremely arduous. Ikki's Phoenix Cloth in particular possessed the ability to be reborn through fire. Its vitality was terrifyingly powerful.
In the anime, Ikki himself was practically immortal, able to resurrect directly even after death. The real-world Ikki surely was not that absurd. Otherwise, an immortal body combined with Cosmo's near-death burst of power would have made him invincible long ago, wouldn't it?
Clearly, reality still followed the manga. Ikki's Cloth possessed the power of revival, but he himself could still die.
Even so, his strength far surpassed that of the current Bronze Saints.
Especially since Shiryu's Dragon Cloth had not been repaired, Seiya, who should originally have had the other Cloths gathered around him, now lacked the Dragon's shield. The battle had gone even worse, ending in another near-mutual destruction.
As the Phoenix Saint, Ikki could not come back from the dead, but his recovery ability was still far greater than that of ordinary Saints. He probably would not die.
But Seiya, lying prone on the ground, was another matter. Moreover, their battle seemed to have triggered Death Queen Island's volcanic eruption. Mr. Mu could no longer worry about arousing Yota's suspicions and directly acted, pulling Seiya off Death Queen Island.

After pulling Seiya away, Mr. Mu directly used his Cosmo to drag Shiryu over as well. Of the Saints on the island, only the two of them had severely damaged Cloths or no Cloth at all. The others had their
