I read Dawn of the Arcana when I around 16 or 17 (despite Caesar being way too pushy in his introduction, tho he mellows out), and it is one of my favorite shoujo manga. I was surprised to hear the series got a spin-off. 

I feel like things are moving too quickly, but the initial premise is already set up. I’m not dazzled by anything, but I’ll consider reading a volume two to see if it can capture my interest. 

SN: There’s a The Water Dragon’s Bride oneshot at the end!
