that's not the face of someone that regrets anything he has done... ugg goddammit japanese author!! I spoiled myself with some chapters and knew she will f*ck up but as I don't know japanese, I didn't knew the conversation was about not k!lling this f*cker, I'm super disappointed at this moment
Guys? They can't kill Bie. Because of the backlash effect that blessed people have. Which is the same thing they are gonna use MC's sister for defeating this "witch" - whoever she is.
And on that note... I'm calling it right now:
This Guardian Saint of theirs is somehow closely related to this "Witch" beyond their relationship with the Farley Church. In fact, it wouldn't surprise me if she is his daughter - this Church seems to have a perverse fetish for using family members against each other.
I say use one of the seedling warriors to bind the Bie feet like you said, drop the mofo into the middle of the sea.
No matter the curse, as long as warrior seed stays inside ten no hira, he should be fine. And warrior seeds can stay indefinitely inside of ten no hira anyways, problem solved.
Let not fault Rosa too much, Bie was bound to understand this at the same time he saw Kai, he knew where he was dropped of. It would be strange for him not to think that if kai survived the island, he could have made a base there.
