Usually when a Monster Lord is selected, the heir to the throne may receive a challenger, such as Cassandra during Alice XV Fifteenth 's coronation. However, during the last coronation, four powerful monsters rose to challenge Alice XVI. Each competitor had their own reasons for partaking in the battle: Alma Elma simply viewed the competition as fun; Tamamo, who was Alice's surrogate mother and the mentor of many Monster Lords before her, felt that Alice was outnumbered and could possibly be unfairly overwhelmed if she did not step in; Erubetie planned to use the position of Monster Lord to eradicate the humans due to their oppression on the slimes; and Granberia wished to test her skill against the daughter of the previous Monster Lord, having no intention of claiming the throne whatsoever.
I know it seems far-fetched to go this far back, but hear me out because there is a connection here. The Mexican-American War was a struggle against further American expansion into Mexican territory and although political divisions within Mexico led to an American victory, the consequences of this war extend much further than the loss of land. The most powerful weapons utilized in war are manipulation and racist ideology and this war was no different. These weapons, Manifest Destiny in particular, helped justify invasion and violence. Although to the American people invasion seemed best for all, it was really only best for them.
