These are the covers of "Atai no Gensokyo", the parent series of the other series by Moyazou. These are usually Loaded Interior and Chaos candidate, so maybe I will need some help to tag the one that I missed

Edit: Nvm, after checking it, it's just this one and the other one that have a lot of stuff in it

This series includes (ordered from pixiv):
pool #14687; Fairy Outdoor Kids Are Healthy Kids
