Updated with English chapter.
They're not English, so once again, will update when it's out.
Looks like Karma works for METI, Terasaka works for the government, Terasaka's gang took on their family businesses, and Nagisa became a teacher of a class full of troublemakers.
Oh, and on the front cover, they're mentioning two extra's. It's supposedly covering Koro-Sensei's private life, meaning we'll see him as an assassin I guess.
Really though this ending is about as obvious as obvious can get.
