A very nice spin-off of fate, and underrated as well. I'll give my opinions on what are my thoughts up-to-date. (Chapter 25) Main protagonist, kinda generic but he has unique reactions to what's going on, have rooms for character developments in the future. (He started more normal than Shirou. He's just a highschooler who accidentally got dragged into HGW) Fujimiya, kinda tsundere I guess? Plenty of character developments as well depending on how the author wants her to be. (More open, as main protag's assistant) Okita, best girl of course but also different from the one we usually see in FGO. This one is a much morecold-blooded but at the same time heart-warming.

Other side characters are good as well. Fight scenes are pretty good. Art is god-tier. However, it's too short. It takes really long to get another short chapter but in the next 2-3 years, I think we will be able to see half of the plot.

Conclusion: Underrated fate's manga. If you like bloody, brutal and good art scenes, this manga is definitely for you. But you don't need to read it now since it just started recently.
