These are pretty cool, especially where there are differences in personality. It looks like Mako was more energetic, and Katyusha was more shy. I guess "Saga of Pravda" already depicts that Darj developed some of her mannerisms after starting at St. Gloriana.
Mika... next to Arisu... again!! :D(secretly hopes their sisterhood gets confirmed in Ep. 4)
Although, considering the difference in station between the two (Mika, rags; Arisu, riches), perhaps Mika was kicked out of the family much earlier than originally postulated. Either that, or that's the only casualwear she has due to it being forbidden by her family or something.
