This clip is a battle compilation, showing everyone using their Personas and some other tidbits.
Starting out, I immediately notice that Pyro Jack is listed by his correct Japanese name “Jack Lantern” here. This is significant because the demons in past trailers were called by descriptions and appeared unnamed in battle. This could mean that an enemy’s true name will only appear once it’s been “awakened” through a Demon Conversation.
Zorro’s skillset: Garu, Dia, Patra. Looks like Morgana will be the primary healer in the start.
