Intro. Eternity City is a bustling dystopian world, full of people, and spirits alike. With the currency being Yen coins. And also weapons, from professional smiths, that use mystical materials from the non mortal plane. With Oni demons being samurai that defend helpless spirits, from humans that wish to sell them. There are no cars or phones, but yet advanced technology, medicine, and giant hologram billboards.
