Actually, the story gets a bit slower, but is still interesting, in the second volume of "Blue Exorcist," Kazue Kato's hit comic about a 15-year-old boy Rin Okumura, the child of Satan. There are more characters, more combat scenes and more secrets arrive (with one of the school's instructors who seems interested in Rin's uncanny abilities more than necessary), but not much happens that will propel the larger story about Rin determined to pay a visit to his father someday.
The second volume (that consists of four chapters) spends considerable pages on introducing some of the important supporting characters including Ryuji Suguro, nicknamed "Bon," who looks like a teenage delinquent but is actually a smart and serious student, and Izumo Kamiki, an intelligent and strong-willed (read "tsundere") girl, whose bossy attitudes are perhaps a means of covering up her insecurities.
It is an entertaining read with likeable characters and nice artworks, but, as is the case with most Japanese comics, you have to read the entire series from Volume 1 to fully appreciate the series' merits. Also, in English edition, you might be missing the meanings of some characters' names written in kanji letters (Izumo Kamiki means literally "divine tree of Izumo, land of ancient gods").
The second volume is an enjoyable ride as the first one, with more emphasis on characters you can relate to.
