Aito took advantage of the night's relatively calm atmosphere to help the siblings raise their level. He had two methods in mind.
First, he assembled all the soul cores they had, and used the candle on them, hoping for some sort of miracle. However, he was severely disappointed when nothing happened.
The candle was a powerful item even gods wanted to get their hands on, but its applications remained a mystery. Aito theorized that maybe after recovering another part, it would unlock some new features.
Who knew?
Abandoning the first method, Aito took out the weak level 2 soul cores he had acquired thanks to the moderator.
