By the way, I don't know if it was mentioned in the earlier chapter's comments, but.
Are they (characters in the manga) so stupid or it didn't come to their mind, that "The Witch's Curse" (his sister's) and "The Witch's Blessing" (his companion's) maybe are from the same Witch, or just aren't a coincidence? Or even worse, jealous Puri and Witch coop scenarios?
