Tilling a field by hand is fun when you’ve got the strength of ten men—though maybe I shouldn’t have fed those Spirit Herbs to my pet rooster.

Ashlock wakes in the courtyard of a demonic sect... as a tree. A tree that eats people. An odd start to a new life. Almost as strange as the humans flying through the skies on flaming swords and challenging the heavens.

I guess trying to catch the bus with your laces undone isn’t such a smart decision after all… One fatal collision later, and I’m facing my judgment. As it turns out, I’ve been a lazy sob, and my short, uneventful life of playing games and getting up late wasn’t worth much. And so I don’t qualify to move on to the afterlife. I try to argue to the goddess in front of me that I do have skills, that it was hard work playing those simulation and management games. But she will not concede. In the end, I manage to get the benefit of the doubt, and a wager is made.
