It seems that this manga is published on the drap magazine (if I'm not mistaken or they changed the magazine). I've heard that the mangaka got sick after the last chapter (4th chapter) and the new chapter hasn't been released on that magazine since then either. I also looked at her twitter and she didn't say anything significant about the continuation.... unless they changed the magazine, i guess we have to keep waiting :P
Ok if someone knows there is a raw for chapter 5 post it I needdddd to know if he lives!!!! Its killing me
