As a Slovak myself (Poland is my neighbouring country), I naturally wanted to read story with Polish protagonists. Although the wordbuilding of Koutetsu no Lucja is quite intriguing - steam knights etc., personally I found this story rather average. From storytelling to characters to drawings, nothing is extraordinary and there is a chance you find yourself bored. There are some pieces of Polish culture (names, food) but that´s it. Although the art is fitting to the story, the characters are quite flat, even MC is generic, at least so far. I would appreciate if the author wrote more about how the artificial limbs are attachedto the body, what about nerves - does it hurt or you can put it on/off as many times as you will? But, there is still chance the story will explain this further, and bring it to nice end.
I read only half of the story so far because chapters are translated very slowly, so I can´t quite predict the end. So far, I would rate it 5/10.
