@Vegetablesucks Just my guess but, some manga publish their chapter in 'parts' for web releases in the reason to enforce people to check magazine for faster whole chapter. Then scanlations that can't get their hand on the magazine go with the web releases and post them in 'parts' as well.
@421cookies ah I see now, thank you. Been wondering since the decimal chapters usually have almost 20 pages, more or less a regular sized shonen jump size, so I'm confused why don't they named them chapter 14.1 and 14.2 instead of just 14 and 15.
