Bubka's got some info on the Gokusen movie releasing this July.
First, the film will be the end of the road for Nakama Yukie. Yankumi is moving on.
Next, Season 1's Oguri Shun and Ishigaki Yuma, along with Season 2's Kamenashi Kazuya, Akanishi Jin, and Koike Teppei might be making appearances.
Also, Shinohara Ryoko may also be in the film playing a very important role as a detective who helps Yankumi.
Lastly, there's talk of Ueto Aya becoming Nakama Yukie's successor.
Meaning... more Gokusen. Joy...
Anyway, no official announcements have been made yet, so you'll have to wait and see if any of this is true.
