You’ve reincarnated and have lived a brand new life followed by your choices here, but the world you wake up in is not the world you were reincarnated. It seems that rather than being reincarnated in the location chosen in setting, you’ve instead been dropped in from another world, the world in which you’ve reincarnated. You may choose the scenario in how you came to be here, whether it was a freak science accident, an enemy technique that threw you here, or something stranger.
If this is taken with Homecoming, you may optionally choose to have come here through a method of choice; maybe you're here on a mission from your home world, or maybe you were thrown here by accident, but you can easily get back. Maybe it’s even a vacation destination for you and your family, or a world you spend half your time in.
Your history and perks are affected by this: If taken without Homecoming, you’ll have just been suddenly dropped off, your family is in your Reincarnation world, and perks and items such as A Pencil. A Fucking Pencil! is only applied to your home world. If taken with Homecoming, you choose how things such as your family are affected, how long you have been here, whether your reputation is in your home world or both, your items, and so on.
You are dropped off in the location and scenario chosen here; your Reincarnation world can be anything you’d like.
