Eh, I wish TMM was MAINLY fantasy mahou shoujo, and not that much of eco/bio story, but I guess that's main intention of this series after all :C I honestly can't say I enjoy this new plotline with Mew Aqua a whole lot... I had more fun reading first volume.
It's not that I hated it or anything though, I just don't think that's the best direction for this series. Well, as long as the drawings of girls keep being this adorable, I probably won't complain too much anyway :3
