Eiro continued fighting 'the Death', with this new ability that he currently had while fused with Koperia's undead. With this, he was able to use quite a few new unique tactics that Eiro's enemy had to adapt to. The formerly child-like body that it had been using was no longer recognizable. The death just looked like a wild beast, and it was acting the same way.
It didn't seem particularly sentient like it was before, and was now instead only acting on the instinct that the death's adaptability programmed into its mind. It was causing its own doom, there was no doubt about it.
However, when they reached the last ten seconds of the countdown that the phylactery was showing to Eiro and Koperia, the Demon still didn't see any point where the death was going to truly die. He knew that at this rate, they would get there in time, but Eiro simply didn't have that time.
