OOHHHH does the paper charm transfers curses to whoever's name is written on it? Im assuming Nana's paper says "Channel all woes to Ebisumori Mutsu" same as the paper charm found in her mother's hand when she died. Mutsu means six so it's def referring to her mom (the sixth priestess). Sooo when that curse/monster from Mirai's room grab hold of Nana, it was supposed to have killed her but it didn't because it "skipped" her and went straight to Mutsu.
Now Mutsu couldve avoided death if her paper charm says Itsutsu (five) but I'm assuming Nana's grandmother is dead and that's why her mother's paper says Mutsu bc there's no other Ebisumori priestess she could pass it on.
That means when Nana gave Kaya her paper charm with her name on it, she was ready to take on any curse in Kaya's place so that she'll remain safe TT
ALSO I wanna talk about Mirai and Nana bc when Kaya's teacher mentioned that Mirai is expecting another (spectre) child, Nana was confused and mumbled "She took it from my..."
SOOOOO I'm guessing back then Nana got pregnant but bc Mirai have always felt ignored all her life for not being a psychic, she wanted to be the one to give birth to the next priestess so that she can finally be noticed by her family. She somehow managed to learn the cursed womb spell but bc she's not a clone of the first priestess, I'm guessing the spell might have taken Nana's child from her womb and placed it inside Mirai instead.
That's why Nana was shocked when she found out abt Mirai having another spectre child bc it shouldnt be possible anymore.
I may be wrong but this is a fun theory to come up with hahaha
