How to achieve:
Stay at Amenaku shrine and don't suspect Amekari of anything, whether it be Tsurikaze's disappearance, or his continuously declining behaviour. This will lead to Amekari offering you a bottle of sake on the fifth day of your stay, accept it and there, now you have the ending.

I woke up with a splitting headache. It hurts so much, have I been drinking too much?
No, this isn't right...
I try to get up, but I feel metal restraints on my ankles and wrists. Due to a headache, I can't see anything clearly. I turn around frantically while struggling to get free to make out my whereabouts.
This place reeks of rot and filth, it makes me want to throw up. Heck, I would've done just that if my head wasn't upright.
[Struggle Even More]
My vision starts to get a bit clearer, I'm in some sort of sacrificial chamber. I see various corpses nailed on the walls, from all walks of life. From elderly, to children. They're all gutted, organs barely holding onto place and their expressions convey absolute agony, eyes wide open and mouths "screaming". This is bad... So bad... Is this how I'm going to die?!
I struggle even more. Have I been caught by their adepti?! But this isn't possible... This village was heavily protected, and Tatarigami couldn't get to me no matter what due to divine protection...!
As I fruitlessly try to get out of my restraints, I hear a creak of the door and hear a familiar voice...
"Oh? Has my beloved Sunao finally awakened?"
As soon as I heard that voice, shivers went down my spine. No... This must be some cruel joke, right?
In my ditch effort, I try to get free once more before that figure comes into my eyesight.
"Hm? What's wrong my dear Sunao? Did you have any nightmares?"
"Amekari! Please let me go! Y-You must be here to save me, right?..."
"Yes, yes... I'll save you alright..."
And when I thought I could regain some hope, he started to cut my wrist with his small knife. Immediately I started thrashing around in my restraints, begging him to stop doing that.
"Oh? But didn't you tell me to save you?" He asks, almost in a mocking tone.
Then I decided to confront the truth. Amekari was standing over me with a small knife that he used to cut bread in his hand, his clothes were bloodied, and his gaze was one of the predator, looking at its prey.
"Come on, let me save you, my Sunao."
I hoped that it was just a ridiculous joke, a Tatarigami's illusion, just a bad dream... But it was all real. What stood above me, was Amekari, quietly yet maniacally laughing at me as he continued to cut my wrist.
"Ah wait, I changed my mind. I'm not going to save you. I want to keep you. All. To. My. Self. ♡"
My wrist was cut halfway through and I could see a glimpse of bones poking through.
"Why... Why are you doing this?! Aren't you supposed to protect us?!"
"This. These are my disliked words. Do you think I asked to be a shrine priest for these maggots? Do you think I enjoy doing those divination rituals? Day in and day out I kept reciting these prayers... And not a simple thank you. Tsk. I feel Tatarigami must've felt the same. People treat you as some kind of idol, yet are disappointed if you don't meet their high expectations."
His knife plunges into my chest and starts cutting it open.
"These people want me to seal Tatarigami up in our shrine, but after my encounter with it, now I understand. That poor thing is regarded as a monster after failing to meet their expectations in this ungrateful job. And now, I want to assist in their vengeance. I will kill people that stand in their way! Hell, I have been doing it for years at this point~!" He rips my skin apart, revealing my innards. I should've been screaming in pain at this, but he must've drugged me. And there's nothing I can do about it, my only hope is to just die already while listening to his ramblings.
"But you are different."
?! What?! He can't be serious! I felt myself getting tense and cringe at his words, and what followed next made me feel like puking the second time.
"When you arrived at our village, I thought nothing could be prettier than my older brother. I was wrong! Seeing your pathetic and confused little face made me feel so ecstatic. I wanted you so much by my side that you made me break my favourite toy - my brother."
"Wait... You were responsible for Tsurikaze's disappearance?!..."
"He was taking you away from me, I couldn't just let him go unpunished. Seeing his pained face while I was sacrificing him to Tatarigami was quite a beautiful sight. Haha... Despite everything, he still thought I was obligated to seal my idol as a priest. Of course he is a weak link in our family, so of course he wouldn't know how much I suffered."

(v Only appears if you have completed all Tsurikaze's events)
Does this bastard even hear himself? Tsurikaze was shunned by his entire village for being the weaker of the two and was forced into his servitude - and that guy didn't make his life even easier, in fact even worse with his constant verbal and physical abuse should he do something wrong. This guy has no say in this!...
---
"But given that at the end of the day - you're still a prayer, meaning I'm obligated to kill you to prove my loyalty to Tatarigami... Although, I think I let Tatarigami handle this one. And right now, I'll enjoy this as much as possible ♡"
And what began were gruesome hours... Maybe even days of pure torture. He kept toying with my innards, while sustaining me to be just barely alive for all of this. He always whispered sweet nothings into my ear, of rather... Perverse nature. I was hopeless on this island as it is, but for him to build some hope for survival, only to crush it like that is absolutely abhorrent. I want to die already.
The worst part is that he kept blaming me for everything. For him killing his brother, for the current unrest of the island, for making him act like that in the first place. I would've objected to that, but given that I can't move at all and heavily weakened, I can't do, let alone say a single thing.
He kept fondling me, while staring at me with icy blue eyes. His breathing was heavy and his hands were shaking, creating this nauseating feeling. I am kept as his personal torture slave for his enjoyment. I doubt he kills people for Tatarigami as he claims to be... He is just a mere sadist.
And when I hoped I could at least meet my end by the hands of Tatarigami... They never came.
And so.
I'm stuck.
In this.
Living hell.
