Balder is the white wolf in the trailer.
Fairly obvious but seeing as how this game focus on Bayo's past and we've already seen the plot is about saving her mom then it makes sense that her old man will pop in some form. Perhaps he'll act as both a guide and protector, using his Wolf Within to hide his true identity in some form. Luka is the white wolf in the trailer.
Luka is depicted as having ties to the fae realm in Bayonetta 3, and that game spent a lot of time trying to portray Luka himself as very important to the greater lore of the series. He also spends a good deal of time as a werewolf-esque creature. Perhaps this game will give further justification to Luka's newfound importance.- Jossed.
