Artist's commentary
Karindou 4 Koma #231
Surrounded by stern but kind maid-senpais, Cuey has grown to be a first class maid.
She naturally has a good memory, so it's not as if she would be unskilled... If there is a problem, it's that, for good or for ill, she's pure. She should really learn to doubt people.
There are 2 suspects about who trained her, but which was it lol.
