Hitman

You're an ordinary girl living in the year 2026. You constantly read manga about the past (especially the 1930s). You dream of going to a ball and experiencing the body of an ordinary girl from the village. But you live in a huge city where this isn't the norm.

You'd just fallen asleep, thinking for a long time before about how cool it would be to be there. In the morning, you were awakened by the bright sunlight and birdsong. You were lying on the grass in a field. It felt like you'd been transported back to the 1930s.
