you probably get this all the time but you're my last hope. I'm trying to find a shinto myth manga about a girl and snake god going around fantasy medieval japan looking for artifacts and hitting up other gods and creatures.

i think the human man was a girl. I thinkt he god was a snake god, but the first artifacts they got was definitely that rope and the mirror. you know what I mean.

the manga started at a festival i think? I only got a few chapters in, closed the page and could never find it again. The manga also had a very pretty artstyle that vaguely reminds me of Ryoko Kui.
