And the culprit is...

Fumiyo scowled as I stared her down.

"To think you'd do what Iroha was going to do just to get back at me. You're NOT Fumiyo!"

"__!"

"Let me explain. You are wearing a wig and shades in order to fool everyone into thinking you are Fumiyo, but you are not. The real Fumiyo's tied up right there. If you were really Fumiyo, you'd have tied her, and me up more erotically. As for why she looks like Miyuu, you cut her hair."

"___."

"Next point! You screwed up! Back on the 1st loop, you mentioned I couldn't have been showering for an hour. But my phone was set 30 minutes ahead. You could only know that if you saw my phone!"

"___!"

"The culprit that can also see the fandom is YOU! Miyuu!"

"Fumiyo" clicked her tongue and took off her disguise. It really was Miyuu.

"Why though? I thought you loved us more than anyone?" I asked.

"When I saw that "fandom" I saw a manga depicting our life up to Kyoto. Then it showed me Iroha beating up Fumiyo and getting scolded by Yoshi, and Yoshi's eventual confession to you. Suddenly, you lashing out against Iroha made sense. I was also furious that you'd be chosen over me. HOW!? You barely did shit! Yet one little encounter was enough to make Yoshi fall for you? I LOVE HIM! You weren't even trying to pursue a romantic relationship with him, yet you got it. I hate you! Once I saw Sara trying to make a move, I decided to launch my plan to get Yoshi all to myself. I disguised myself as you in order to fool everyone. I almost got caught by Iroha, but I needed to make you think SHE was the ultimate culprit.

Then, I suddenly found myself back in gym class. I guess I got sucked back along with you. So I got bolder and bolder. Then you finally snapped and slugged Iroha. You becoming violent would make Yoshi hate you. Then I simply pushed Iroha to the brink, and then I just had to get Yukino out of the way. And I did! Yet I'm back here again! WHY!? I HAD MY HAPPY ENDING!"

"How could you call that scenario happy!?"

"I told you I'd plow anyone down to get to be with Yoshi. And that's what I did."

"Miyuu? What are you saying?" Yoshi asked.

Miyuu turned to see Yoshi, Iroha, Yukino, and Sara all standing behind her.

"Ah, we were just bantering," Miyuu nervously lied.

"Why do you have a wig that'll make you look like Fumiyo? And why's Fumiyo tied up and looking like you in the shed!?"

"Uh, she's just doing role play. She wanted me to shave it all off, but I said no and just cut it."

"You're lying. I know you well enough to know when you lie. You're one of the more upfront and direct people I know. But why are you doing this? I thought you cared about your family more than anyone."

"I met you. I want you. Love made me do all this."

"Well then let me clear things up. I don't love you Miyuu."

"Hah?"

Miyuu began to tear up and fall to her knees.

"I just didn't have feelings for you. Your bold advances also made me uncomfortable. I'm sorry my silence drove you to hurt your sisters," Yoshi apologized.

"I guess I should come clean too. Yoshi and I are engaged," Yukino stated.

"Because of your insensitive parents correct?" Sara asked.

"Yes. I'm sorry I hid this from you all. But I truly do love Yoshi."

"I'm sorry Yukino, but I don't feel the same way about you," Yoshi stated.

"Oh, I guess I should have seen this coming. I just took it for granted that you loved me back when I realized my feelings."

"Yona, I love you. I'm sorry I couldn't bring myself to tell you earlier, or that I'm telling you after all this just happened."

"It's OK. I love you too," I smiled.

"And what about me?" asked Sara.

"I think you're an amazing woman. If you need help to overcome your anxiety and become a fashion designer, we'll help you," Yoshi replied.

"I heard Takemichi could help. Grant me an audience with him and yourself."

"OK?"

"Mmmph ngh mmph," Fumiyo mumbled.

Oh right! We forgot to untie Fumiyo!

We quickly rectified that mistake.

"Ugh, didn't even hogtie me," Fukiyo pouted.

I then pulled up a message from the fandom.

*Congratulations new poll rank 3. Save point updated. Good ending achieved. Do you wish to go back to your original timeline or continue in the new improved timeline. This choice is irreversible, but will result in the fandom vanishing for you and Miyuu regardless of your choice*

I'm curious to know if things are really improved though.

*They are. Even Miyuu will become happier in this timeline*

Alright fandom, though let me see the comments one final time.

"Yona time looped!? Insane."

"So in this version, Miyuu goes bad. I kinda like it. It's a nice what if."

"Lol Hi Yona! You're my waifu."

Let's continue with this timeline shall we. And with that, the fandom vanished.

"Ugh, so now what," Miyuu groaned.

"Well, I think you deserve a punishment, then we return to our happy days," Fumiyo stated.

"You'd still be friends, even after I did all that horrible stuff?"

"I mean, all you did was tie me up, cut my hair, and go on a crazy rant."

"Oh right..."

"Don't worry Miyuu, I'll help find someone that will love you," I smiled.

"Ugh, I guess I don't hate you after all," Miyuu grumbled.

"As for your punishment, you're going on a date with me," Fumiyo smirked as she began dragging Miyuu off.

"DATE!? WE'RE SISTERS!"

"Relax, we're just gonna have a girl's night out. Oh yeah, tell father we're rebelling, Yona, Iroha."

Well I guess we'll have to deal with him.

When I told father about my relationship with Yoshi, he was upset, but begrudgingly accepted it. When I told him about Miyuu and Fumiyo, I was banished to the room where I had been grounded in. Iroha then offered to undergo proper training to take over the shrine, soothing my father's mood.

"Well, onee-san might not be good at a lot of things, but at least she can manage a shrine," Iroha smiled.

As for Miyuu and Fumiyo. They didn't get home until 5 in the morning.

 Miyuu was nearly unrecognizable when she returned. She now sported a spiky blonde pixie, had no eyebrows, and had a wind kanji tattooed on her shoulder. Father was furious and promptly shaved her bald before grounding her and Fumiyo.

"Ugh, well I guess this is a lenient punishment," Miyuu sighed as I brought her and Fumiyo dinner.

"We're gonna match her in a few days," Fumiyo teased as I angrily pinched her cheeks.

We ended up graduating a few months later with everyone else with no issue. From then on out, things mirrored the original timeline, but were overall improved.
