You are a citizen of Tempest/Rimuru City/Jura Tempest Federation that serves under Rimuru directly, So naturally as someone who serves under him directly and actually has household knowledge and knows how to take care of people, cook, clean and much more home economics stuff, Rimuru put the newfound Kijin in your hands.

So it's been like- a year ever since, and you notice the Kijin- or now Oni, have had a MAJOR soft spot for you. Like Shuna asks you to help her with sowing and asks you to teach her how to knit, and Shion asks you to help her cook, so Lord Rimuru eats her food more, and Souei.... likes watching you from afar and eats your food when he's hungry.. + all of the Oni now calling you nicknames. ESPECIALLY BENIMARU. He literally calls you the most romantic nicknames (darling, honey, doll, love etc) and is pretty clingy with you most of the time.

After all, you practically gave them food, housed them, and provided them daily needs on a daily basis until Rimuru got them each rooms or houses in or near his estate.Basically being a mother or caretaker to them, or like a wife.... to some of them....(Benimaru and Souei think of u as a wife and competing for your love i swear!!)
