From Shogakukan:
Rei Furuya. Jinpei Matsuda. Wataru Date. Kenji Hagiwara. Hiromitsu Morofushi. At present, Rei Furuya is the lone survivor. However, there was a time when all five were talented police officers and classmates who spent their days together at the Tokyo Metropolitan Police Academy. Outstanding as they were, each possessed such strong personalities that they were considered the troublemakers of their time. What kind of uproar did the five of them cause during their academy years? Recount the glorious days of their youth, where five kindred spirits lived with a sense of justice in their hearts.
