Two of the characters are half-siblings Oscar Dragonia and Teresa Linares, exorcists who the main characters of Tales of Berseria will eventually meet up with in-game later on.
Mystic Artes return in Tales of Berseria as well, special attacks that can be used via the Blast Gauge.
As praetor exorcists, Oscar fights against Velvet as she flees from Titania, the prison island.
