Parry Mountains spoke very decisively. Angel thought it involved class solidification, or some other hidden affair, but after hearing Parry Mountains' subsequent explanation, he realized the reason was actually very simple.

Parry Mountains and Nami Midori were born in the same era, and their birthplace was in Lost Forest. Therefore, they have been familiar with each other since the elf era.
However, due to differences in talent and later different encounters, their ultimate strengths were worlds apart.
But the issue of strength did not affect their friendship, as seen from Parry Mountains living in Lost Forest all along.
Moreover, a long time ago, Parry Mountains even resided in the center of Lost Forest.
