Half a year after the turmoil that rocked the entire city of Ikebukuro.

Peace has once again returned to the city and people are living each day normally. The high school students enjoy their days of youth as the strongest and most dangerous man of Ikebukuro works diligently. The informant plots (or plans) a new scheme and the headless rider is pursued by the cops as she rides through the night... But soon this normal will be cut short by the abnormal. Slowly but surely, the unknown will seize the city and face an all new storm.

THE GOOD, THE BAD, AND THE DOWNRIGHT WEIRD.The Ikebukuro district in Tokyo is full of interesting people. A boy longing for the extraordinary. A hotheaded punk. An airheaded pseudo-stalker. An information broker who works for kicks. An underground doctor who specializes in truly desperate patients. A high school student infatuated with a monster. And a headless rider on a pitch-black motorcycle. Their story may not be a heartwarming one, but as it turns out, even weirdos like these sometimes fall in love.(Source: Yen Press)
