Clearing the rumors
Millie started a rumor by spreading information saying "Kaneki Higanbana and Miku Tachibana are step-siblings" which spread like wildfire and even got Shino and Yuuka involved.
The rumor even changed to revealing the identities of Shita-chan, Miyu-chan and Miha-chan, that being Shino, Yuuka and Miku.
Because of that everyone in school started to pity Kaneki and started to turn on those 3 all according to Millie's plan, all she needs now is Kaneki to confirm that him and Miku are step siblings.
Except, there was one problem.
Kaneki's thoughts*
(Alright, Phase 2 of my plan shall commence)
Everything was planned out by Kaneki.
Kaneki: Are you guys stupid?
When Kaneki said that everyone looked at him surprised and for Millie.
Millie's thoughts*
(What?! You're supposed to admit it! Wait no way)
Millie then realized she messed up.
Kaneki: you guys really believed stuff in the internet? Have you guys heard of fake news or false information?
???: what are you-
Kaneki: what I'm saying is that you guys shouldn't believe in that false information.
???: but you never talk about your sister.
???: yeah, you don't even say her name.
Kaneki: do you seriously think I would tell my sister's real name to people she doesn't even know?
Everyone: !!!
Kaneki: and for your information Tachibana-san is not my step-sister.
???: but the information said-
Kaneki: like I said don't believe in false information, that's what the bully wants.
Everyone was shocked to hear Kaneki mentioning a bully.
Miku: wait what are you talking about?
Kaneki: this entire thing is probably orchestrated by the bully who is targeting you.
Miku: Eh?!
Ryueki: what?! What makes you think that?
Kaneki: simple, I did reveal that I was helping to find the bully which would be bad for them and somehow they learned of it so in order to stop me from trying to find them and to hurt Tachibana-san, they probably stalked in some way and actually learned of my sister's name and used it to make a false rumor.
Keiko: wait are you saying?
Kaneki: yup, my actual sister's name is also Miku.
Everyone: EHH?!
Kaneki: I don't really like showing this but, this is the picture of Me, Sachi, Shita-chan, Miyu-chan and Miha-chan along side my sister Miku Higanbana.
Kaneki took out his phone and showed a picture on his phone.
Itsuki: wait these are your friends?
Kaneki: correct. And this is my sister.
She showed a picture of "Miku" to everyone.
Kaneki: you guys seriously believed in false rumors. You guys are the worst.
Seeing that they all messed up everyone bowed their heads to Kaneki.
Everyone: We're sorry Kaneki!
Although Kaneki didn't accept their apology.
Kaneki: it isn't me you guys should be apologizing to.
Kaneki then pointed at Shino, Yuuka and Miku.
Kaneki: it's your fault for believing the false rumors and they ended up getting hurt so you guys should apologize to them.
Everyone then started to apologize to Shino Yuuka and Miku.
Kaneki: seriously, you guys shouldn't believe in rumors without any evidence.
???: we're so sorry Higanbana-kun!
Kaneki: it's alright.
Millie: but how did you know that it was sthe bully who was targeting Miku the culprit?
Kaneki: who else can I suspect?
Chikao: good point. So does this mean you're going to give the bully a harsher punishment now?
Kaneki: Yup! I'm pissed off now! Not only my other friends got involved but my special friends and my sister got involved! I'm going to gouge their right eyes out!
Chikao: by the way, where's Sachi?
Kaneki: she's probably on her way here now, she did wash her dishes after all.
Chikao: Ahh~ okay.
Kaneki: it's great that not everyone belied in the rumor.
Natsuki: it's hard to believe that everyone in school believed that rumor.
Itsuki: yeah, whoever believed in that rumor is so dumb.
Keiko: yeah! At least we di-
Smack! Smack!
Kaneki smacked Itsuki and Keiko's heads.
Kaneki: don't talk as if you two didn't believed like everyone else!
Itsuki & Keiko: we're sorry.
Kaneki: geez, seriously.
Shino: hey Kaneki.
Yuuka: thanks for helping us back there.
Miku: I'm sorry for getting you and your friends and family involved.
Shino, Yuuka and Miku came to Kaneki to thank him and apologize.
Kaneki: yeah yeah whatever, and don't apologize, you've don't nothing wrong.
Miku: yeah...
Shino, Yuuka and Miku then went back to their seats.
Kaneki: seriously, I feel bad for them.
Chikao: yeah, you definitely need to find this bully soon.
Kaneki: I know, it will be soon until I find the bully.
Everyone: huh?!
Everyone heard Kaneki and when he said that everyone was shocked.
Millie: what do you mean?!
Kaneki: confidential.
Chikao: yeah, there's no way he's telling.
Kaneki's thoughts*
(Alright, with that the Millie will get more desperate and she'll try doing other more extreme things and I'll get more evidence against her thanks to Egu-san right)
Kaneki's plan is to Millie more desperate but why?
Millie's thoughts*
(Dammit! What should I do? My plan has failed! I can't do anything as long he's nearby... In that case I'll have to learn more about Miku to hurt her more! Not only that I have to make sure the two of us are alone)
Miku started to grow desperate, what will she do now?
