I was searching for something in the fanart section and found y'all talking so I think the blonde one is the maid because maids usually aren't allowed NOT to have their hair tied up usually. It's very rare to see a maid with long flowing hair because it's considered to be a burden while doing maid stuff like cleaning cooking etc.
2 things.
1) Souleater, Mei isn't a top. She is simple on top for different reasons.
2) It has been more than a month and i am so hyped for the next one.
@Vankomycin @Hollows (late comment lol) I don't think that stereotype exists in Japan. Instead, it seems Neet are the ones to usually wear tracksuits, like Hina Araki from Idolmaster, Barusu from re:Zero and Kazuma from KonoSuba, or poor people, like Yato from Noragami and Rinne frpm Kyoukai no Rinne.
