manga. Among the many, many series I could argue are openly appealing and addictive are Fumi Yoshinaga's Antique Bakery , Takeshi Obata and Tsugumi Ohba's Death Note , Ai Yazawa's Nana , Kazuo Koike's Lone Wolf And Cub , Naoki Urasawa's Monster , Takehiko Inoue's Slam Dunk and Kiyohiko Azuma's Yotsuba&! .
