I tried translating parts of this. In the third panel, Remilia's going crazy over the meat sauce or something, then in the last panel, there's mention of "the Scarlet Devil," which is Remilia's title because she always gets her dress stained red from feeding.
All in all, it seems like a joke playing on the title referring to pasta sauce instead of blood, in this context.
She is notoriously known among her maidservants as "the Scarlet Devil".Remilia ScarletSakuya,The Scarlet DevilWhat's for dinner today?However, this means that she spills so much, her clothes are stained a deep red.Yes, pasta-Due to her light appetite, she never finishes all of her food.Meat sauce is the best!Will this... ever get out?YAAYY!!!
