Here is all the Freak Island/Kichikujima chapters in English at the moment, translated by Usarei Translations (1-21) and myself (22-45). I took the liberty of compressing the original chapters done by Usarei as they were far over blown in size for some reason. They are far smaller in comparison now thankfully.
Now if your wondering why there hasn’t been a release of Freak Island in the last few months that’s because the next volume or even chapter for that matter hasn’t been released and whenever that will be the case is up in the air at this point as Masaya Hokazono is working on spin off of some sorts.
With Sasamoto making himself at home it seems Haji has been visited by the based old man from before. Whatever took place is a mystery, but Sasamoto isn’t having any of it and goes to town while Jezza pleasures the trumpet.
