The order feels a little messy, so just bear with it. There’s no Yuki Suou because the author made a separate one for her. As for the older sister’s name, I’ve seen both Maria and Masha used, but the fan translation I read used Masha, so I went with that:)
玛莎(Masha) 1-119p 俩人一起(Masha and Alya) 120-198p 艾莉(Alya) 199p-249p
