Ok, three current theories. Most likely one, Natsuka is just Oota’s relative, because he said some of them lived around the area. Second, she’s the ghost of Kashiwada’s grandma, because that chapter with her granddad seemed to imply she was in a similar situation to the one Natsuka mentioned being in the chapter before that one, but I’m not sure anymore because grandpa would’ve recognised her in that case, right?
Now, the third one though, and the one I’m starting to lean towards now with her not knowing any of the snack brands, seeming to know Oota and understanding how to handle him early on, but also understanding things about Kashiwada and their dynamic and all that… I wonder if she might be Oota and Kashiwada’s kid from the future or something?
