@Mammon just look back a couple chapter, you can actually see Kyouka’s p*ssy if you look closely in her “waterfall training” image, all thanks to the water, and the author doesn’t even resort to putting it somewhere else (in droplets of water, reflections of a chrome water tap, etc) like to love Ru does 😂
@blanc_ the new volume was released a day before this chapter was published. So the artist and the author took a break to commemorate the release. It's been like this when a volume it coincides with a chapter release. Other mangaka practice it too i.e. desuraba, social survival rabbits, etc.
