The youth in front of him didn't look special in any way, but the purplish-pink transmuted mana he saw within the youth seemed weird, as Jason had never seen such transmuted mana before.
His mana eyes could only work perfectly fine if he knew all affinities and the color of its transmutation.
However, right now, the only thing Jason knew for sure, was that the youth in front of him was at the 1st Expert rank, while his mana core size was at the 3rd Expert rank. This indicated that he contracted a soulbond which was either at the peak-evolved rank, or that his soulbond was a low-unblemished beast. The former was only possible if the youth in front of him possessed a soul world with a slightly higher amplification than the average.
Either way, it wouldn't make a huge difference, because it was not essential for Jason to know, who thought what about his opponent's affinity.
