I’m not sure if anyone has mentioned this but I think I know what Zuboshi scrapped design was inspired by. I think it’s inspired by this artwork👇 (the link is in the replies)
It may be a teaser for Up-Coming stuff, but the Tsukiya part in the trailer is a bit strange. We never really see a teaser of her in her own minka, and she randomly appear on the city on the trailer so i counted it as a unused content maybe in the testing game Tsukiya was suppose to be an hallucinations to Isamu at the start of book 2
You can see this unseen monster in "The Mimic Unused Content" Wiki or you can also watch my latest video about him! Here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-R6v1YjypVTs.htmlsi=VKo--UN8UAj5q4PL
