Tsu's Twinsanity Effect

By TheBlackKid

Chapter 1 – Graduation Girls

So…this is what it's like to have your own story, huh? Never did I believe that an OC like me would get sucked inside this "Inner Struggle" thing the others were talking about. Figured that it was only for Official Characters.

But honestly…once I told Akari my secret, I was kinda expecting it to happen.

I mean…why wouldn't I? I did reveal to someone the secret that I've been hiding for years. That I'm a parallel doppelgänger from an entirely different world and my other self…well…more like the one who was originally born in this world…is out there somewhere after not speaking to her for nearly 6 years at this point.

I didn't really have a choice, okay? Even though Akari was high off raspberries at the time, she did see me use my powers in a last-ditch explosion to get us out of Akemi's clutches.

Though, I wasn't really trying to escape Akemi. I was trying to escape her.

Who is this "her"? Well…I-I'll bring her up later.

But for now…I guess I should get this story started, huh? I'm still new to this kind of thing. So, please try to bear with me…

…as I explain my Twinsanity Effect.

It had been about three months since the whole Raspberry Incident. All of the goopy vomit had been mostly cleaned off (some of it got stuck inside the walls and it would sometimes leak through them) and everyone tried to forget the horror that was brought upon them that day.

Though, as a precaution, any and all raspberries were permanently banned from the school grounds. A request made by…pretty much the entire school.

Nowadays, as we continue our high school lives, this special little group of ours is on our way to bigger things in the future.

And it all begins today with...

"Ugh…my head…"

"Geez, Akari. I said I was sorry. You don't have to keep whining."

"I'm whining because it hurts, Chinatsu! You don't know what it's like to be dragged into a pole at full speed!"

"W-Well…it's a special day and I wanted us to get here on time. You and your poor eyesight would've made us late."

"We were an hour early, though…" Both Akari and Kyoko said with exasperated looks.

"W-Well, I…sh-shut up!"

Even though she screwed up the time, Chinatsu was right about today being a special day. Today was March 19th…Graduation Day for schools all across the country. And it was no different for Rise-senpai, Iyo-senpai, Ariana-senpai, and Madeleine-senpai.

It's gonna suck not going to the same school as them anymore. Especially since I only knew three of them for less than a year. And never got to know any of them on a personal level. But I'm sure we'll all still be friends. Even when they're in college.

Wait…will Madeleine-senpai even SURVIVE college?

A-Anyway…the rest of us were going to watch the graduation ceremony as Japanese schools tend to force first and second-years to watch it no matter what. Either way, we were pretty excited to go and show our support.

"Ugh…why?!"

Well…most of us.

"Will you two quit complaining already? It's required. So, just deal with it." Himawari said to Sakurako and Kei as us underclassmen were in the clubroom. Listening to the duo complain about being here.

"But why, though?!" Sakurako whined."Why is it SO important for us to sit in a chair for hours on end…listening to a speech and singing a song and clapping for EVERY SINGLE THIRD-YEAR as they get their diploma?! It makes no damn sense!"

"Why can't they just give them the diploma, tell them "good luck", and have us go on with our lives?" Kei added."Get it *yawn* done and over with…"

"Get it over with?!" Chitose asked with a shocked tone. "Graduation Day is supposed to be a special time for us all! A huge milestone for when we as students have completed our education and get sent out into the real world to jet start our careers! It's a sentimental moment for everybody!"

"Sentimental my ass!" They both whined.

"Aw…" Making Chitose sad a little.

"You know…you're one to talk, Kei. You're graduating next year." I pointed out.

"Tsu's right." Ayano said. "By this time next year, YOU'LL be in that front row bare witnessing it all."

"You mean I'll have to go through all that crap AGAIN?! Ugh! That blows!"

"Ha! You have to suffer!" Sakurako gloated.

*POW*

"Ow!"

"It's the same for you too, dumbass." Himawari said after hitting Sakurako in the head.

"Tsukasa, talk some sense into him." Yui said as were all turned to face her.

Unfortunately, though…Tsukasa wasn't much help. She was sleeping on the bed we had cuddling with one of the pillows. Not listening to the conversation at all.

"Seriously…" Yui gained a sweatdrop.

"Well…Tsukasa isn't really a morning person." Akari said.

"*mumble* *grumble*" It was this time that Tsukasa started talking in her sleep.

"One more life…and then it's night-night forever. *giggle*"

And we were all creeped out by what she just said.

Wh-What the hell does that mean?

The creepy sleep talk would've continued longer if Rukia hadn't finger-flick Tsukasa in the head. Waking her up instantly.

"Ow~! What was that for~?!" She whined.

"For nearly stuffing our minds with that creepypasta nonsense. We don't need another Iyo-senpai around here."

She ain't wrong about that…

"Anyway…" Yui continued. "…It's going to feel rather different with the third-years gone."

"Yeah, no kidding." Ayano said. "The four of them are going to be doing their own thing once April rolls around."

"I'm going to miss them." Chitose said. "Especially Rise-senpai."

"Uh…guys…" Chinatsu, Himawari, Sakurako, and Kyoko said while pointing over at Akari…who had a look of pure depression as she was curled up in a ball facing away from all of us.

"A-Akari?"

"She's been like that all month, really." Chinatsu said. "The fact that she'll rarely see Rise-senpai is really getting to her."

"I don't blame her." Chizuru said. "The two have been together since middle school. I would feel the same way."

"Akari…" Tsukasa said. Feeling bad for her friend.

"I-It's *sniff* okay…r-really. I-I can handle *sniff* b-being without Rise…t-totally possible. Hahahaha…*sigh*"

She really is taking it hard…

"I knew you would be acting like this..."

"R-Rise!"

"What are you doing here?" Ayano asked as we saw Rise-senpai enter the room.

"I had some time before the ceremony started. So, I came by to check up on Akari."

"I see…"

"R-Rise…I-I don't *sniff* w-want you to leave!" Akari said as she began to cry."I-I'll be *sniff* s-so lonely and…"

"Akari…we've been over this. Just because I'm going to college, doesn't mean I'll ever leave you."

"B-B-But…"

"I'll still make time for you. Hell, I'll force time for you. You'll always be my top priority and I'll never leave your side. I love you too much to do such a thing…Akari Akaza."

"Rise…" Akari wiped away her tears and grew a huge smile on her face. "Rise, I LOVE YOU!" She then cheered greatly as she hugged her girlfriend in pure bliss. Happy for the kind words.

"Well, at least she's feeling better." Yui said.

*SOUND OF INTERCOM*

*Seito to kyōshokuin no minasan, chūmokudesu. Dai 90-kai Shinohara kōkō sotsugyōshiki no jikan ga yatte mairimashita. Kakyūsei, kazoku, raihin no minasan wa taiikukan e okoshi kudasai. Sotsugyōsei no minasan, doko e iku ka wa minasan gozonjideshou.*

*SOUND OF INTERCOM*

"Well, it's time." Rise-senpai said as she had let go of Akari. "I better get back before Ariana throws a panicked fit. I'll see you guys there."

She then turned towards the door with a pissed-off (and actually kinda scary) look on her face.

"Especially YOU two~. Sakurako and Kei~."

"Tch!" The duo stopped with chills as the rest of us had just noticed them trying to escape throw the door.

"You two weren't plaining to skip this event, weren't you~? I would be VERY sad if you did~." Rise-senpai then swung her right hand for her iron bat to appear.

"W-We weren't plaining to skip!" Sakurako yelled in a panicked fit. "I-In fact, we were rushing to get the best seats! R-Right, Kei?!"

"Y-Yeah, totally!" Kei added in the same tone. "W-We would NEVER miss out on this special moment for you, Senpai! H-Honest!"

"*giggle* Well, good~." Rise-senpai said before making her bat disappear. "See you all there, then." She then left the clubroom with her normal personality intact. Making the duo (and the rest of us) relieved that what just happened was over.

"J-Jesus Christ…" Kei said.

"I-I've never been more scared in my life…" Sakurako added.

"You know that it's absolutely unnerving that she can do that now, right?" I asked Akari.

"Yeah…I know." Akari replied with a sweatdrop.


Soon after Rise-senpai left, we all went to class and then eventually went to the gym by class for the graduation ceremony. In my case, it was just me and Rukia. None of the other second-years were in our class.

The ceremony itself was as what you would expect from a Japanese high school graduation. The Principal made a speech, Ariana-senpai made a speech, we sang a graduation song (take your pick. They're all basically the same, really).

And then everyone got their diplomas. All 300-something of them. And we had to sit through them all. Clapping and cheering for them.

If there was one thing both Sakurako and Kei were right about graduation ceremonies is that they ARE too long. I nearly fell asleep a few times…

A-Anyway…after all of that and school was let out for the spring break, the rest of us underclassmen head over to Rise-senpai's house for a huge celebration party.

A ton of people came. Akari and Chinatsu's older sisters, Ana-sensei and her scientist twin sister (first time I'm meeting her), Haruka & Sanae, Rise-senpai's little sister Risa, the girls of Rakuyama High, Jeb (who's helping Rise-senpai's parents make the food. They're somehow okay with that), and even the new additions to our group being Kanako and Chiharu.

The latter of the two…I'm currently having issues with. It's not like we don't like each other. It's more like…

"And so, without further ado…"

*POP*

*POP*

*POP*

"CONGRATULATIONS!"

Well…I'll tell you later.

"Aw…thanks, you guys. It really means a lot." Ariana-senpai said after everyone cheered with party poppers in hand for the four graduates.

"Hahaha! To be cheered for by our now-former kōhais…I LOVE being a graduate!" Iyo-senpai cheered.

"Hey, calm down." Rise-senpai said. "You're not a high school student anymore. You gotta act more mature."

"Aw, it's fine, Rise. I got like 3 more years before I have to change my personality. There's still plenty of time to dork it off a little more."

"You're off by one. It's actually 20."

"S-Seriously? Damn…" Iyo-senpai gained a concerned look.

Did she not know that?

"So, that was the ceremony of graduation…C'était si beau!" Madeleine-senpai said. "The song of goodbye was rearry soothing...and Ari's speech was so mesmerizing. I had the tears run down mai face."

"Glad you liked it, Madeleine-senpai." Chitose said.

"Oui, en effet!"

"Arthough..." Madeleine-senpai suddenly gained a sad look on her face. "…The current setting of it arru...I did not know that the rand of Japan had cherry burrossom turrees. It...reminds me of mai home."

"*sigh* Maddie…" Ariana-senpai said with a sad look of her own.

"Something wrong, you two?" Haruka (the adult) asked.

"Well…it was always a dream of ours to experience a graduation ceremony the French way. It's not a grand as the ones Japan has, but…it's our home, after all."

"Haven't you guys ever thought of going back to France?" Ayano asked. "I mean…nobody's stopping you."

"Yeah, but…if I go back, it's going to highly difficult for me. I don't have a family…and since I was adopted into another country, I probably won't be labeled as a French citizen until a few years in. So, I might as well stay here where it's easier."

"I see…and what about you, Madeleine-senpai?"

"Werru...I dó miss mai rittre sisteru. But otheru than that, I thinku I wirru stay here as werru."

"W-Wait, what? You have a little sister?" Iyo-senpai asked.

"I did not terru you? Mai rittre sisteru is named Zoé. She is 17-year-ord and is in the ereventh gurade in haigh schooru. "

"11th grade? Wow, so she's already in the grade that we're about to start." Himawari said.

"How is that even possible?" Chinatsu asked. "Isn't the school year supposed to be done?"

"Here in Japan, yes." Ariana-senpai said. "But in France, the school year starts in September and ends in July. Meaning that at the same time you guys finish your 1st term, her entire school year would be completed."

"August being the vacation of summeru remains identicaru in both countries, though." Madeleine-senpai added.

"Haa…I don't get it. It's all too random for me."

"Maybe we'll meet another French person and hear from her how OUR school year calendar is weird." Sachiko said.

"What are the chances of that happening?" Takane asked.

"It could happen." Kyoko said. "After all…we do know a few people who are through changes of their own."

"Really now…?"

But are they considered "inner struggles" like ours? I wanted to ask that, but decided not to. I still don't understand how I got involved in this concept. Knowing these "other people" would probably make it more complicated.

"Well, in any case…" Sakurako said. "…the fact that you are staying makes all the more reason to celebrate! LET'S GET WASTED!"

"HELL YEAH! TIME TO GET TURNT UP, BITCHES!" Aoi shouted.

*POW*

*POW*

"SHUT IT!" Yui and Himawari yelled after hitting the duo hard.

"Wasted?"

"Turnt up?"

"What does that mean?" Kaede and Mari asked with confused looks on their faces.

"Um…well…" And I was about to come up with a simple lie for them when…

*HEARTBEAT SOUND*

Tch! O-Oh no…not again!

"H-Hey, Tsu. You okay?" Ayano asked me as I was holding my body in what seemed like pain.

"U-Uh…y-yeah…*clears throat*…I-I'm fine. Just need to…Tch…u-use the bathroom!"

"It's down the hall and first door to your left." Rise-senpai said.

"Th-Thanks!" I then got up and rushed over to the bathroom. Locking the door behind me before looking at the mirror.

Just in time for my rainbow markings to fully show.

"*pant* *pant* D-Damnit…th-that was a close one. Wh-Why did it had to *pant*…sh-show up now?"

If you remember from the raspberry incident earlier, the end result of it all was that I had exposed my powers after keeping them hidden for most of my life. And I told Akari that I was a parallel doppelgänger originally from the Nega Dimension. Due to events that happened before I met my large group of friends.

And now, three months later, I'm struggling to keep it under control. The aura within my power would often overfill. Causing the markings to appear all over my body and the feeling of intense pain lasting for a good 30 minutes. Sometimes even an hour.

And the only way to calm it down…is to release.

"T…Tuyuu Fourot!"

*SPLURT*

*FLUSH*

"*pant* *pant* *pant* D-Damn…i-it's a lot more *pant*…th-than last time…" I said as I had flushed some rainbow-colored ooze down the toilet. Causing the effects to subside for a while. "A-At this rate…I-I won't *pant*…l-last much longer."

"Then why don't you do something about it already?"

"H-Huh?" I reacted to the sudden new voice. And grew into a shock once I saw who it was. "Ch-Chiharu?!"

"Oh, I'm sorry. Did I startle you? *giggle*"

"Tch! How did you get in here?! I locked the door, didn't I?!"

"I came in through the window. It seems that the people of this dimension don't lock their doors and windows. Pretty careless of them don't you think, Tsubaki?"

"Ugh…quit calling me Tsubaki already." I said in an agitated tone.

"Why not? That IS your name, right? The one you've had ever since you came to this world."

"Just because it's my name doesn't mean I have to use it. How do you even know that, anyway?"

"I know a native of the Nega Dimension when I see one. It wasn't that difficult to figure out."

"*sigh* Damnit…" I mumbled to myself.

I've always had this in the back of my mind…but I believed that Chiharu knew I was a doppelgänger. Ever since she looked at me funny after breaking free from Akemi. And because of that, it's been rather tense between us.

Mainly because…

"Since we're on the topic of "coming to this world"…when do you intend on looking for your other self? Taking your time?"

"No…I don't need her." I said in mild anger. "If she can push me aside like she did six years ago, then I can do the same. I can handle this on my own."

"Really now? Fufufufu…well, that seems to be working for you, Tsubaki. Flushing your aura down the toilet and all…"

"L-Look, you!" I began to yell (but not so loud that everyone outside could hear). "You've been on my ass ever since the incident with Akemi and I've had enough of it! Just because we're both doppelgängers doesn't mean you can just hover over me like a damn mother!"

"If you want me to stop, then admit to your problems already! You're DYING, aren't you?!"

"D…Damnit…" I said in pure sadness as I sat down on the toilet. Filling my eyes with huge tears.

I never thought I would ever have to admit this…

"Okay, fine, damnit! It's true! I'm…I-I'm dying! The moment I unleashed my power that day was the beginning of my demise! And now every time I go and release all of this built up aura…I just *sniff*…I-I just get closer and closer! To the point where I'm weaker now than I was three months ago!"

Everything then went dead silent as I continued to cry. Only stopping after a few minutes in.

"*sniff* I-I just…*sigh* I really gotta go ask her, huh?"

"If you wish to stay alive, then it's your only option." Chiharu said.

"Wh…Why? Why do you care so much? We never knew each other…not even when our world was normal…so, why?"

"*sigh* Look…" Chiharu said after going silent for a while. "…when our world became the Nega Dimension, I bared witness to tons of my friends dying slow and painful deaths. Some were done by Akemi's hands…while others just couldn't take the endless suffering and misery that "new world" brought onto them. And took their own lives."

So, she suffered, too. Hard to tell when she hides it so well…

"I'm lucky enough to still have Kanako with me…even though the trauma and manipulation Akemi brought onto her made her stupid as hell. But I refuse to have any more people from that world die. Akemi may have nothing to do with your situation. But even then…I want to save you, Tsubaki. And I won't stop until I do."

"Ch-Chiharu…" I sat there in pure shock after hearing all of that. Then, unexpectedly, started to laugh a little. "…Man. You really are different from Chinatsu. She would never say something THAT cliché."

"Hmph. It might've been cliché, but at least I'm dead-ass serious about it. "Flat-chested Chiharu" would've expected a kiss from all of that."

"Yeah…I kinda get that from her specifically." I gained a sweatdrop.

"*sigh* In any case…the sooner we fix this mess, the better. First thing's first is to find your parallel self."

"But I really don't know where she is. Six years ago was really the last time I saw her."

"Oh, you can just leave that to me." Chiharu said with a small grin on her face. "I can track down any lone mortal like a cheetah hunts for its prey. She won't hide from me much longer. Fufufufu~!"

"Uh…" I gained a concerned sweatdrop.

That sounds creepy as hell…

*KNOCK* *KNOCK* KNOCK*

"Hey, Tsu. You okay in there?" We suddenly heard Ayano's voice. "You've been in there for quite a while…"

"U-Uh…yeah! I'm fine! I-I just…drank a lot earlier! Really got a flow going on here!"

"Ew…" Chiharu whispered.

"Shut up!"

"Well…o-okay then. Food's ready. So, when you're finished, we all eat together."

"O-Okay! Be right out!" I said as I flushed the toilet filled with nothing to make it sound more convincing. "*sigh* That was a close one…"

"Fufufufu…Wow, Tsubaki. To think you would have a kink for pissing…totally not like you~. *giggle*"

"I-I do NOT have a kink for pissing!" I yelled at Chiharu with a full blush on my face. "*sigh* Look, can you promise that you won't tell the others about this? I mean, I had to tell Akari because…obvious reasons. But I don't want to drag any of them into this."

"Yeah, yeah. I get you. I wouldn't want them getting involved, either. Just keep your aura intact long enough for this to work."

"Easier said than done…" I said with a depressed sigh.

As I left the bathroom and went back to join the others (Chiharu snuck back out through the window and somehow made it back before me without anyone noticing), I was introduced to the surprisingly delicious cooking made by Jeb. I thought Chitose and Chizuru were joking about how it would "changed your tastebuds forever". But I swear…one bite and I was completely lost in heaven.

No food should've tasted THAT delicious! How the hell did a talking mouse outclass all the human chefs in the world?!

I-In any case…some hours later, the party ended and everyone had gone home for the day. I was walking home with Rukia as we live pretty close to each other. Been like that since we were kids. And now…we're in our final year of high school together.

Pretty insane, really.

"*moan* Man, that food was good!" Rukia yelled out. "And I can't believe I can't have THAT instead of the bland crap my chefs cook at home! I wonder if Jeb is interested in a job…"

"You would seriously let Jeb cook for you?" I asked.

"I mean, why not? He's good at it. Despite being a rat. I just don't get how he learned to cook in the first place."

"From what Chizuru told me, he said that he listened into a cooking class in America."

"Oh…"

"W-Wait, so how did he get to Japan?!"

"Probably due to some logic we don't understand at all." I gained a sweatdrop.

"Huh…" Rukia went silent for a bit. "…Well, whatever. More importantly…can you believe that in just two weeks we'll become third-years ourselves? Such a milestone for us two, you know."

"Yeah, I get what you mean. It's the final step in our path of education. After this, we're on our own." I then took my own words to heart. As the phrase "on our own" may have either a good or bad ending attached to it.

Damn…now I'm less excited about it…

"Tsu…Hey, Tsu!"

"H-Huh?! What?!" I came out of my train of thought.

"Geez…are you okay? It isn't like you to space out like that."

"O-Oh, um…*clears throat* yeah, I'm fine. Just tired, that's all." I then made a fake yawn to make it look more convincing.

"Huh. Well…okay, then. I'll see you later, then. The three of us might do some last-minute volleyball practice before the new school year starts."

"Sounds good to me. See you later."

As the two of us went our separate ways, I couldn't help but to get sad over this ordeal. It's my final year of high school with my best friend…and I may not even live long enough to experience it to the fullest with her.

All because of who I really am.

Sometimes I wish I was never a doppelgänger…

Author's Note: So, if this story looks any and all familiar to you, it's because it was on the site nearly two years ago. I took it down in favor of the rewrite…but I'm putting it on here mainly for one reason.

You see…the next chapter of The New Band Mate is going to require a ton of context that's in THIS story. And rather than explain it there, I would just repost this story.

Now, to make this clear…this story is a CONTINUATION of the series. Yuru Yuri: The Inner Struggles is a REWRITE of the series. Meaning that, at some point, this story will be rewritten. So, what you see here may or may not be in the final rewrite. The same goes for the other 7 stories in this series.

As to whether or not I will finish this story…that's still up in the air. But I already have 5 chapters done. So, it's technically halfway finished at this point.

Thanks for reading. Later.
