Great storyline, very interesting full of everything I like in a manga.
Action, non-confusing plots
The characters are beautiful, the design is precise and ahh~
*Edit* As you go on, I feel like the artwork is slowly starting to lack in places and get a bit lazier, but it still looks great.
There are a few bit's that look a little odd, but it's still pretty good artwork.
The two main female character's personalities are my favourite.
I love how Teiru is so oblivious to what's happening.
It's quite an enjoyable manga, haven't finished it yet, but definitely finishing.
