If I had point out an issue this manga had, I'd say it focused a bit too much on Gotchi and Miss Knight experiencing regular things.
It's funny at first, but it loses its charm if you do it every chapter. That being said, I still very much enjoyed it. Shame it got the axe. You can very clearly see a lot of inspiration for Miss Knight from Artoria Pendragon (Her dress is almost exactly the same as Artoria's.)
Hope this author gets to do another manga soon!
