Namely, the ghost of the previous Demon Lord, Gustav, has been witnessed roaming what remains of his former domain. Kelvin decides to go check it out with Ange, but much to their disappointment, all they find in the ruins of Grebarelka is a golem. Needless to say, they're quite surprised when they later return with Sera on a visit to her hometown and discover Bell Baal, an Apostle, waiting for them!
