This was a decent enough romcom. The aspects to being a ninja and the duty based relationship resulted in a pretty interesting relationship between the two. However, it also resulted in one that moved incredibly slowly. The side stories were decent enough, so it didn't feel like it was dragging on too much, but they did seem to feel like they were getting repetitive and pointless at points. The comedy only being okay and action being weaker than I expected didn't help. The main couple's personalities came through pretty well and got some solid development. Most of the side characters, especially the alternate romantic interests, felt really underdeveloped and someseemed to get dropped completely without any sort of conclusion. Still, there were a few that got solid development, such as Takatou, Kujou, and Kiritani. The ending was also handled quite well I think, bringing things to a reasonably strong climax, and with an extensive epilogue. The art was decent.

tl;dr: A solid but somewhat slow rom-com.
