The bean paste inside Sakuya species is pudding.
Pudding is the favorite food among Remilia species
So it is possible that they show off their loyalty to Remilias by offering their own fillings.Details are under investigation.In the experimental environment there was no food available.
So Sakuya offered her own feces as a meal.
Remilia did not show any reaction such as smelling a strange odor, and ate all of the feces.As a result, Sakuya easily welcomed the stray Remilia as her Mistress.
