Toz was happy that he had established a bond with another cat type spirit beast, but he was also conflicted about having another elemental attribute that he needed to train. And considering his lightning attribute was at the first level, it would take some time to get it to the fourth level, even if he already had the experience with the three other attributes.
With the time he needed to spend reading the grimoire and learning the spell in it, and with how much time he would spend walking, there wouldn't be much time left for him to train his mana, which once again prompted him to try and find a way to train it while walking.
Compared to the time in Sleepless Brights, before he reached the fourth level, he had an easier time controlling mana, especially the lightning mana still at the first level. Although it was a completely new element with its own unique behavior, it was still much more easily controlled compared to fourth level mana.
