Why are people saying it's going to end soon? There is evidence to the contrary (like The "finding a way to turn Mika human again" arc among others and the progenators including Ferid's and Krul's motives). If sensei's past works are anything to go by, I'm guessing the main baddies are going to be psycho general and Guren (possessed). Unless they cover all this in the next several chapters (which I doubt), this isn't going to end soon.
New chapters only come out once a month, people. The next chapter will be out around a month after the last release.
