Arashi and Mikoto finally arrive at the NEO TV building. Now the real fight can begin.
Volume 4 is getting closer to being ready. There's still work to be done, but I don't think it will be too much longer. In case you didn't know, Volume 4 doesn't include any chapters that weren't already scanlated by XLG, but the quality is much higher and there is no censorship. Also, there are color pages and the usual stuff that comes in volumes. Volume 5 will be out on August 9, the same day as the art book, so you'll have to wait a little longer to read new chapters.
Maken-Ki! Chaper 49 will be up soon.
