The story of Death note is divided into two sagas. The first saga consists of the first seven volumes. Surely this saga is the best. We can see the battle of wits among L. Lawliet and Kira (Light Yagami). It's one plot twist after another.
The second saga is worse than first saga. Some key characters are vanished, and some situations become repetitive.
Takeshi Obata is a great illustrator. I love his dark style.
Very good manga, many plot twists (the ending is incredible), not much action, but much reasoning.
For the most part, the characters are good (Lawliet is the best!).
Maybe not for all. Anyway reccomended.
