A Marisa gives an interview regarding the Marisa Farm she's raised in. Marisa explains that the Marisas in the farm are nurtured and trained to eventually become kings.
And she's not lying, they do end up as kings. They're livestock that get processed into canned bean pastes with the brand name "King of Pastes" (lol)
