i found a manga store, a rarity here
they had TONS of manga, but more unexpectedly they had a hentai area tucked away in a corner, even a big oppai figurine which was very expensive
but they didn't have ANY yotsuba volumes, the clerk told me there won't be any reprints and if i want one i'll have to find someone who is willing to part with them at a huge price, i am very sad because of this
