very fun and interesting story, feel all excited going through all the god,demon, and sacred treasure it give me sense of nostalgia like when i first watch the 1986 journey to the west.
In the original legend of En no Ozuno, the two demonic disciples Zenki and Gouki would eventually marry and settle down on Mt. Oomine in Nara. These are also the same Zenki and Gouki from that '80s anime Kishin Douji Zenki - well, except there Gouki is a dude.
I was worried this was hentai by the cover but I clicked on the first chapter Very adventurous and intriguing with how the author meshed science time and spirits.
