QP: Soul of Violence

Children cry in fear just because his looks. QP (real name Ishida Kotori), known across the town as a legend who used to go to Bonten High, has returned after a four year absence. Working at a gas station, he's trying to live a quiet life, but his old best friend Azuma Ryou has something else in mind. Azuma intends to have Kotori stand at the top of the gang he has been building since high school. Despite his best intentions, is QP forced to fall back into his violent ways?! After a four year absence, Ishida Kotori (QP) returns to the city where even his face instills fear amongst the locals. Trying desperately to move away from his once violent past and live an honest life, former classmate and now high profile gang member, Azuma Ryou, has other plans for QP's future... QP: Soul of Violence is written by Takahashi Hiroshi and set within the same universe as his other works, Crows and Worst.

Worst is a high impact gang-related title that deals with teenage boys fighting their way through high school in order to gain respect. There is no room for deceit and underhanded tricks at the notorious High School "Suzuran." These young men follow a strict honor code when it comes to brawling, very reminiscent of the mafia in the early days.

QP (Sequel)

This is one of the three Crows Gaiden volumes done by Takahashi Hiroshi himself. It says Crows in the title, but really, it's more closely related to Worst than Crows. It focuses on Tesshou's and Guriko's year, so it's set the year after Crows (main series) has ended. There are only one or two minor Crows spoilers in there, so you can read it without ruining your enjoyment of Crows. It's also an ideal entry point for those who want to read Worst without having to wait for the Crows scans to finish.

Worst Character (Data) Book. Even though these are data books, they each contain Omakes, or Side Stories: Book 1: Makka ni Nagareru Book 2: Umehoshi (2 Chapters)

The first of the 3 Crows Gaiden volumes written and drawn by Takahashi Hiroshi (the others being Sono Go no Crows / Crows: The Aftermath, and Zoku - Crows Gaiden / Next Crows Supplementary Story), this volume contains 3 chapters surrounding the Ebizuka Trio, Bandou Hideto, and Bouya Harumichi). All of these are origin stories and can be read at any time.
