"Unfortunately, this step was necessary," she sighed wearily. "At the time this seal was developed, the power of the high priestesses was much weaker, and maintaining Yashiro no Fuin required enormous effort to counter the powerful demons. The chance of failure was high, so the appropriate seals were added which sacrificed the priestesses but removed the demons' ability to resist during the fusion process, as well as increasing the reliability of the seal by allowing the human mind to dominate the dull but powerful creatures.
"This will only work with the unintelligent, but if there is someone like Morieu, he will simply devour the human mind," I shook my head, "it's just like trying to dominate a bijuu with the power of a simple shinobi, and it always leads to the collapse and death of the one who tried. I doubt that the result will be any different here.
Ha, yes, it's just an exotic way to commit suicide! It's like trying to seal a nine-tailed fox without knowledge of fuinjutsu, using only brute force. If I'm not mistaken, the seal simply allows the minds to connect without any protection from the priestess, and whoever overpowers and devours the other with sheer willpower wins.
It's clear that a human has practically no chance, while the demon will devour a very nutritious victim and only grow stronger.
What complete nonsense! In the past, when the priestesses were weaker, this really did increase the chance of getting rid of an uninvited guest, without even strengthening them by absorption, but now, judging by what we've seen, even Miroku is very strong.
Unfortunately, my senses didn't allow me to assess her properly, but based on logic alone, each new generation must be stronger.
"I saw that the seal would work, even if it meant my death, but divided and sealed in two temples, the demon will eventually be erased by the world," the woman shook her head, brushing a strand of hair from her face and looking me straight in the eyes. "It is the duty of all the high priestesses of Oni no Kuni for the sake of world peace.
"How about reworking the seal? Given your powers, which can easily erase demonic chakra, with the protective functions of the seal, theoretically, Morieu could simply be killed or weakened enough that it would be possible to seal the fuin based on chakra without any problems.
"Unfortunately, I don't know enough about seals to radically rework Yashiro no Fuin," the priestess shrugged.
"My grandmother invited a specialist from Uzumaki, but he couldn't guarantee that the reworked seals would work properly due to the difference in the properties of spiritual power and chakra, and testing would not be possible for obvious reasons. "Hmm, let's say that some classic signs and seals will indeed react differently, even if the yin-yang ratio of the chakra differs too much from the standard values, not to mention spiritual power, but it is possible to make a new fuin," I rubbed my chin thoughtfully and began to pace around the room, thinking aloud under the hopeful glances of the girls.
"The first stage neutralizes the user's obvious disadvantage — fragility — and at the same time immobilizes the demon, so what's stopping us from leaving these three seals and adding an attacking element? With enough power, this would solve both defense and attack issues at once. In the second stage, there are some specific examples that would be easy to integrate. And for reliability, you could make a version that uses only chakra so that shinobi could use it specifically against demons. Against mobile targets, it would be complete crap, but if you take the chakra reserves of several ninja at the jonin level, it would be quite possible to hold a creature at the one-tailed bijuu level for some time and allow the priestess to destroy the demon without unnecessary danger.
