It seems that Chapter 45 was cut off a bit short. To summarize, the immortal rakshasa revived himself by using the dead/fatally injured agents. Then, he causes the floors to collapse to distract everyone while leaving with the rakshasa in the basement. Before leaving, he warns Maru, who is hiding with Eden and Chana (their hands covering his mouth), that he'll be back. After evacuating, the lady chief with purple hair has a thought bubble that this entire fiasco happened within 10 minutes
It would be so funny if the crown prince actually unseals the demon king only to be beheaded or tormented for eternity since obviously demonic contracts always have hidden clauses and backstabbing.
