Who Little Sister?

' That was really fun, right big brother?', I turned around and Yua is standing infront of me. I didn't got the chance to taste the ice cream, but yeah, it was really fun, ' Oh yeah, did you say that you need my help?', Oh yeah!, that, There is this book that's from a black and gold carriage that is fastly traveling, Haru said that the carriage dropped this book, I showed him the book and her eyes went wide, ' this book-, is owned by my mother ', Huh?!, are you sure about that?, My heart just skipped a beat, ' I'm sure!, look at the name at the front of the cover ', I turn the book cover and read the name signed infront of it, ' Elizabeth Higurashi ', Yeah that name really is familiar. Well if you think of it, a powerful book like this really suits auntie's power, but how did she dropped this then?, I asked. ' Uh, Mother is using it as a fan and her hand slipped and it got thrown outside the window ', Those things really happen!?. If that's the case then, I should return this book to her, let's go and head back home!, ' Wait!, last thing, your envelope!, read it first, your mother said that, before we leave, read this letter and follow the order inside it no matter what ', that sounds really sketchy, my mother won't say something like that if there's something important happening. I grab the brown envelope on the table and opened it, I began to read the letter and there's something written on it, that I don't have any idea of. ' Bring your little sister ', Who is she talking about?, ' I didn't know that you had a little sister ', Yua questioned, No I don't have one!, if there's one, I should know by now.
