Gumi walks into the club, sneaks up behind Miku, and pokes her.
"GUMI! I haven't seen you in forever!" exclaims Miku.
"I know, right?! What're you doing here?"
"We were gonna go to IA's party, Kaito and I, but it was cancelled. Do you know anything about that?"
Kaito comes back from getting the dessert for Miku. "Here you go, munchkin!"
Gumi asks, "Isn't it here?"
Miku thanks Kaito and then says, "Wait, what?"
"She relocated the party here. Why else would everyone be here?" states Gumi.
Kaito says, "Oh, that explains it. We didn't know, we just came."
Gumi smiles. "Cool beans. Are you guys having fun?"
Miku's eyes go wide as she stuffs pudding and cake into her mouth. "Mhwmmhwame Gagamhwn mhwns mnhvmidddd?" She swallows and tries again. "Sorry. What I was trying to say was: Wait, are the Kagamine Twins invited?"
Kaito motions to Miku's face and says, "You have a little something... There."
"Never mind that! The other day, I brought out Rin's dark side! You know how she gets: homicidal psychopath. And when she's in her dark side, Len is too: with his weird servant gimmick! I get that we were programmed with dark sides to make some good songs, but it sometimes really bugs me! Gumi becomes a very unpleasant person, Gakupo and Luka are able to reduce anyone's heart to dust, Teto literally goes insane, IA and her demon self, Meiko and her odd drunk prostitute personality, even you Kaito... You get possessive, overprotective, and won't let anything stand in the way of getting what you want. But I'm the worst... I'm the "victim." My "innocence" causes great harm... I never tried for Cantarella to happen: I was just in one of my moods... Sure everybody liked the song, but I felt horrible over what I made you become, Kaito. Because when I turn to my dark side, any Vocaloids near me also turn to theirs... I don't feel so good. I think that side of me is coming... I better go to the bathroom where no one is, so I don't affect anyone else..." Miku runs crying to the bathroom.
"Miku, wait!" Kaito runs after her, but the door of the girls bathroom slams in his face. He leans against the edge of the door. "Miku, munchkin, are you okay in there?"
The sound of her weeping suddenly stops.
"Miku?" There is no response. "Miku, come out munchkin. At least talk to me, please. I hate to see you like this." There is a strange silence; Kaito knocks on the door. "Miku? Come on. Are you okay?" A thud comes from the bathroom. "Miku?! Please, are you okay?! Please come out!"
A girl walks out of the bathroom and looks at Kaito. "Is that your girlfriend, with the long blue hair?"
"Yes, is she okay?"
"Was she drinking?"
"No, why?"
"She's passed out on the floor; you might want to help her. Don't worry, there's no one else in there. Umm, bye." She leaves and Kaito walks in to see Miku on the floor. Her heart is still beating... Softly...
"Miku!" Kaito runs to her side and cradles her in his arms. "Are you okay?" He starts to lift her more when Luka walks in.
"Whooaa! Guys, the middle of the girls room is not the right place for... Wait, what's wrong with Miku?"
"I don't know. She's not waking up."
"She looks so pale... Lets take her to Dr. Takahara."
Luka and Kaito drive Miku to a hospital. She gets set up in a room, and after a few minutes, a doctor walks in.
"What do we have here?"
Miku looks pale, which brings out the black streaks of mascara that nobody bothered to wipe off her face. Her hair lays in a dull, tangled mess around her head-it's down now. She looks fragile: like she is made of paper thin glass that will shatter if the tiniest breath touched her. There was an unseen dark aura around her, slowly filling the room. Is it strong enough to affect anyone?
Kaito worriedly says, "She just passed out. I don't know what happened. She wasn't drinking. She just collapsed..."
"I see..."
Kaito pleads, "Please help her. Please."
Luka steps in and says, "Is there anyone else that could help us? We can't leave Miku like this!"
The doctor says, "It seems to me that her dark side got the better of her. The way hers is programmed, it can pressure her system like this. But the program is great for songs! I loved Cantarella: the results were so pleasing! I'm not sure why you don't try to get her like that more often! She's such a stubborn girl, but she is much more willing in her dark side. What she brings out in you makes it even more entertaining! I'll go get her a stabilizer and leave you all in here with Miku." The doctor leaves and the dark aura continues to fill the room.
Kaito quietly adds, "But her dark side seems to hurt her..."
Luks responds, "I know... Dark side hmm... We all have one; Why is Miku's so different?"
Kaito walks over to where Miku is laying motionless in the hospital bed, as pale as ever. "Miku? Honey? Can you hear me? When is the doctor going to stabilize her? I can't stand to see her like this."
The door opens and IA walks in. "When I heard the news, I had to come over! What's wrong?" IA's hair is slowly turning black. "What's wrong?" Her hair is changing more rapidly.
Luka thinks for a moment and says, "Maybe a song..."
IA starts, "I don't get i-" Her face becomes blank.
Luka screams, "IA! Doctor! Quick, Kaito, go to Miku! Go help her!"
IA's hair is completely black now. Her teeth become sharp and jagged, and a tail forms. Her eyes, though still blue, have a red gleam. An evil look comes over her face.
Luka shouts, "Kaito, now! You need to sing to Miku!"
IA changes back for a split second. "Quick! Get me out of here before-" She changes again to her demon form. "I'm going to kill you!"
Kaito starts to sing, but it's having no effect.
"Hang on, I think I know what might help." Luka runs out of the room.
IA changes back again. "It's Miku's dark side! It's changing us all! Get out of he-" She changes once more.
Kaito runs out of the room and leaves IA. "Doctor! Please, something is going wrong!"
"Is IA still in there?"
"Yes! She's also in her dark side."
"Get IA out of there! Miku's dark side is to strong to be with other Vocaloids right now!"
IA laughs monotonously from the other room.
Luka comes running back. "I brought Len and Rin. They know how to help."
"IA could easily kill Miku while she is in her demon form. Get her out first, " says the doctor.
The Kagamine Twins say, "Step aside. We'll get IA."
"Be careful," warns the doctor.
"Don't worry about it! We'll try to help Miku while we're at it!"
"Here. Take the stabilizer."
Kaito asks, "What do I do?"
The Kagamine Twins open the door. "Hope and believe!" They enter the room.
Luka tells Kaito, "Trust them."
Kaito sighs, "So I can't do anything..." He sits in a chair.
Len and Rin burst out of the room with IA, who is back to normal now. "We had to use the stabilizer on her. Miku can't be helped with it. Kaito, you need to try and sing to her."
"I tried before I had to get out."
Luka thinks aloud, "Unless..."
Kaito asks, "Unless what?"
"Unless a dark side song is sung, Miku might not get better. At the end of dark side songs, we return to normal."
Kaito says, "Lets try it."
The Kagamine Twins suggest, "Seven deadly sins?" Everyone else nods and they start to sing. Miku cries, somewhat in agony and desperation, and then she is silent again. Kaito starts to pound on the door. "Miku! Are you okay?!"
Luka sputters, "D-do we have to be in our dark sides to fully wake her?"
Rin thinks, "Maybe... Len?" and Len responds, "Yes we need to."
Luka sighs, "You know how much she's affected by Cantarella... I know she wanted to forget, but that song really can do things to her..."
They enter the room. Shadows dance on the wall and Miku wears a pained expression on her face; eyes still closed, still pale, and almost lifeless. Rin starts to get affected by the dark side, but Len is able to snap her out of it. One by one, they start to sing.
When the song finishes, Kaito whispers, "Miku...?"
Her hand twitches.
