For a while there, I was scared that Sayumi would fall to the devil (Sagami) but she managed to keep to the 'straight and narrow path'. Whew! I'm glad. So I guess after this volume we can stop pretending it's a supernatural battle story and call it what it really is: a high school harem romcom. I guess this is taking the path where there will be a single winner rather than all agree to share him. Which means I probably have quite a bit of romantic angst to read through in the following volumes.
I am still laughing at their antics. The best scenes for me are where they all interact with each other. It reminds me a bit of Haruhi Suzumiya but with a nicer (dare I say cooler) male protagonist/ narrator.
