I think this series has started to bore me. >_> I finished this one sitting (after installing CCCP that finally makes all the AVIs I downloaded working!). Jeda, Art, and the guy with an insect mask started to make better appearances on episode 19. They were mostly in the shadows in the previous episode/s. Kaoru goes on Nekomimi transformation that I think is rather odd and OOC of her. Kouhei undergoes serious training including climbing mountains without any ropes, safety gear or any support. Isn’t it crazy?
I thought this was going to end up some loli-romance stuff. 
I’m glad it didn’t. I like lolicon, but I never got to appreciate the anime ones. The ending of Tsukuyomi ~Moon Phase~ is, err, okay. I can’t find the right word to describe it. The last episode only showed how everyone was doing. Oh, grandpa and Elfriede were alive. WTF. Then I thought there was something wrong with Kouhei’s grandpa, but it wasn’t properly explained. WTF (again). I was thinking of reading the manga. The anime though doesn’t give much reason for me to do so. Hazuki’s a vampire who doesn’t seem to be of much use — she kinda dragged everyone down & without Kouhei’s blood she’s almost helpless. I overestimated this show. -_- Watch this if you’ve got time to waste. The series would have been properly reviewed if it weren’t for the fact that it bore me; forcing myself to finish the series because I don’t usually stop watching when it’s almost ending.
