Man I'm having such a good time reading about all these girls shenanigans, this has rapidly become one of my favorite comedy manga and you're the sole responsible, mycropen. Thanks a lot for nice an quick the translation!
I get this feeling that Yamashiro is misunderstanding Yatsude somehow... I hope they all get along (Because Yatsude and Yamashiro in the beach would take me to heaven... but I doubt things could get resolved by then)
