I picked it up just to fill in the slack between Naruto and D.Gray-man updates and just piled right through all that has been posted (up to chapter 41 on the site).
It's amazing, the artwork and the stories. One by one you're drawn in by the characters and kept wondering about them. The manga adds twists and turns, giving you something else to wonder about on top of what already has you wanting to read it. Along with the beautiful pictures and the short clips explaining why Senri has no mouth sometimes, in example.
It truly is a wonderful manga, if you like anime and animals, it's a must read. Comical, beautiful, suspenseful... it has it all.
