This story shows how people devolve into Malicious Looping Entities in time loops. Pretty great, but I decided not to rate a ten because of the way Ikumi was treated, and the way someone else transmigrated in addition to the regular time loop stuff. There is also the fact that Mukai forgot something really important that was only remembered at the end. I strongly suggest this, and I believe this is underated simply because people find the crimes within unsavory. Even if you find rape and murder unsavory, you will probably still enjoy the story simply because it is so awesome.
