Rin and Erix used full-time in Limitless Plane to explore and expand different ways of the Chaos concept.
Their progress to reaching the 2nd realm concept was slow because of the nature of the concept. Both of them could see many possibilities on how they could direct their Chaos concept forward, but that also prevented them from progressing.
Their understanding of those possibilities was still vague and not solidified. They didn't know how and which way should their Chaos concept progress.
But they could only try without giving up despite knowing their dilemma.
On the other hand, Isabella and Aria made significant progress. Aria even succeeded in awakening the Ice element, reaching 1st realm in Ice affinity in her first Limitless Plane session.
Isabella had been trying to awaken the Magma element since she had focused on the Fire and Earth combo for the past week and also succeeded today.
With Magma, Isabella's affinities numbered five.
