Kaleid always had some leaps in quality over the years, but 3rei is definitetly the biggest one by far, i go as far as to say that it became one of the best Fate Spin-offs because of this part, every arc is filled with action, the plot has both intense moments and also moments that are filled with sorrow and emotion, and expecially an amazing art, every arc also feels meaningful to the story, always keeping the reader interested in the events, the only bad part about it is how long it takes to release a new chapter. 10/10: An underrated gem of Type-Moon history
