Checkmate

'H-How did this happen?!' Arundel, who had suffered serious injuries after getting punched twice by Mammon, stared in horror as the Fiend descended from the sky.

He was certain that the Fiend of Wealth and Greed couldn't care less even if he were to conquer the Valbarra Archipelago. 

For the most part, Mammon only cared about wealth and treasures, so his invasion was not enough for him to make an appearance.

Arundel had been very cautious from the start, and he even asked the Majin Princess, Kamrusepa, a favor to do a divination for him.

Kamrusepa had assured him that Forneus wouldn't make an appearance, which was the only thing that worried Arundel in his grand design for the Valbarra Archipelago.

The Majin Princess was spot on, and the Sea Monster was indeed nowhere in sight. However, someone else had come, which made the one who had the title of "The Destroyer" feel as if the one who was going to be destroyed was him.
