Maid Monday, the sub-series where I post and rate maid designs.
Solution Epsilon from Overlord written by Kugane Maruyama and illustrated by So-bin.
Gotta say, showing my bias here but probably my least favorite. I just don't like the skimpy French Maid design. I know it's kinda seen as the default maid for most casuals, and it has some fans (for good reason, when done right it is very sexy.) But it's just not my thing.
That being said, I can't deny Solution Epsilon kinda pulls it off. I think it's the smug Ojousama face combined with the thigh high armor boots. I'm not really into people stepping on me, but if Solution Epsilon demanded it, I'd let her step on me.
Outside of that, she's probably the most vanilla of the Pleiades. The only other thing I can think to add is that I love the pattern on her armor.
Probably a Dress tier, but that's mostly because of my bias against the French Maid.
