I really love this manga. Lots of wheels within wheels.
The mention of magic tools breaking down over time makes sense, and further cements the comment about the kingdom being able to take over the world.
Ogre-chan thiccer than a bowl of oatmeal.
But all this art is so good, I love seeing concept art and design sketches, and all the race-swap, clothin-swap, era-swap, gender-swap ideas are SO interesting to me!
