I would love to see Collei featured with the hooded person because he put the archon residue inside Collei in a dormant state. I really like people who are willing to help others and are knowledgeable in their craft to turn the tide of events in their favor. I'm hoping we get to see this manga's story in a quest in the future in Sumeru, and who knows, there may be tons of mysteries waiting there to unfold.
