This first volume involves a girl who time leaps. She goes BACK IN TIME to the end of the Edo area. By the time the series over she's fucking two guys at once...
More specifically she was called back in time because a chief who was supposed to live was stabbed to death, so as to fix and preserve the future timeline. I think she is a reincarnation of him from the future, but is female, and has been asked to become the chief of the millitary police in his place.
(Btw it's written for women.)
This burst took a bit of time to prepare so don't expect many raws after this one.
