Kuro charged forth with a barrier of his own Destruction Energy covering his body, planning to break through the veritable torrent of opposing energy that was being sent down by the older Black Dragon.
However, having the indomitable will to push forward despite the difficulties ahead was certainly nice and definitely made for cool TikTok phonk edits, but in reality, it could only take one so far.
Kuro struggled to make progress beyond the 50th platform, which he reached rather rapidly by burning up his energy. As might be obvious, only Lucitian and Lucitera among Draco's children had the Chaotic Eternal Bloodline with 100% capacity unlocked.
For all the other children, they suffered from the same problems Draco did when he only had 99%, which were the limitations of energy and maximum power. While the energy recovered really fast, it was nothing compared to the consumption needed to maintain his barrier.
