Two-Faced Monkey Gangs
After they discussed the missions together, they decided to pack their things and head to The Guild, which would be preparing the transportation for them. Fortunately, The Guild would provide transportation, or else they would be stuck at the Demon Continent as their target destination was very far from the Demon Continent.
Neither Samiel nor Yvraine had any means of getting to that Monkey Island, as Samiel started calling it. Ironically though, the unofficial name of the island, which lacked an official name aside from the formal coordinates, was nicknamed Two-Faced Monkey Realm Island because the Two-Faced Monkeys have been living there since immemorial.
Samiel would be using his Undeads to the maximum in this mission and because the Imp Tribe has completely retreated from the island for the times being until the path was cleared for them, he could use his abilities to their fullest potential.
