After being lost on his way to a camp site. The high school student Ken Kazutoki finds himself in a sacred forest where he comes face to face with a weird heterochromia eyed goddess named Sifina. Do you want to live in a parallel world? She asks, telling him to leave his life behind and start a new one in another world. Ken however still has a life he can't leave behind so he disagrees. Unfortunately for him, whatever choice he makes doesn't matter in the end as she sends Ken into the parallel world anyway. With not a goal left behind by the goddess or even a cheat to make his life easier. Ken reluctantly starts his journey into this unfamiliar world.
