As the title of the episode says, it's the appearance of the big boss and also a reappearance of a certain character in ep 0. There wasn't much of a big fight and it looks like the Lord of Calamity is just testing the capabilities of Sorey. I was just wondering: if a person says that making a pact would put a big burden on Sorey, shouldn’t there be signs of him being exhausted afterward? It feels like the studio is glossing over this with the great animation during the pact scene, since Sorey doesn’t even look tired afterward 🤔. Anyway, that’s the only inconsistency I’ve observed in this episode. This is a great end for the cour and another new beginning for Sorey and Alisha, there are still some question left unanswered but let's just save it for the second cour.
