ＧＴＯ パラダイス・ロスト 改 raw 第01-16巻 [GTO Paradise Lost Kai vol 01-16]

From Kodansha:
Great Teacher Onizuka is back, and the next stage for his legend is prison? The trouble magnet of a teacher reveals that this stint behind bars is thanks to a certain incident with the class he became assistant homeroom teacher of half a year earlier: Kissho Academy’s new class for high school-aged celebrities! Does he regret the exploits that landed him in the slammer? Heck, no. In fact, he’s all too happy to calmly tell his fellow prisoners how the whole thing went down. If they’re willing to listen to his story from the very beginning.

Note: The author left Kodansha and the original run was discontinued after Vol 20. The series is being republished as Paradise Lost Kai with corrections and additions after chapter 99.
