Just finished watching this anime! The story is amazing and I really want to know from which novel this has been taken. If anyone wants an anime which is a combination of action, mystery and romance, I really recommend this one!! What I liked about this anime are- 1. The story 2. The sound mixer is just amazing 3. The characters are entertaining 4. Every scene is of high quality, even the intense ones What I disliked about this anime is that till where I've searched, I couldn't find season 2 so I really need a season 2, WELL, more than season 2 lol
