1. Ubel Blatt - Its a dark fantasy manga. Its art is great and the story is personally the best among the best. Each chapter's plot just makes you keep reading for more.
2. Tsubasa Reservoir Chronicles- Practically the first manga to drive me to tears (Kurogane's Past). Just a shame its ending is half tragedy.
3. MX0 - Well, its a very amusing manga, on how the main character tries very hard to act as a strong magician when he has actually no magical powers.
