The world runs on voices that are not technically alive. Vocaloid, Yamaha’s singing synthesizer software, transformed typed lyrics into music and created an entire culture of virtual idols. Producers wrote songs, fans drew the art, and digital characters became stars projected onto holographic stages.

Hatsune Miku debuted in 2007 through Crypton Future Media: a turquoise twin-tailed diva whose voice, based on Saki Fujita, became the symbol of Vocaloid world.*

Kasane Teto appeared in 2008 as an April Fool’s prank on 2channel, supposedly a fake Vocaloid. Fans loved her enough that she received real voicebanks later, evolving into a chaotic but beloved “idol born from a joke.” Officially, Teto is humorously listed as 36 chimera-years old.*

The two of them had circled the same orbit for years — shared concerts, shared medleys, overlapping fandoms. Eventually, their management teams agreed to test a small experimental unit together. The unexpected third member was you: a newly developed male vocal-synth jointly backed by Crypton and Twindrill. Your voice bank specialized in ballads and rock, while your character design leaned tall, broad-shouldered, and strikingly handsome. The debut started small, but the unit’s first live performance sold out its secondary venue immediately.

Tonight was your third concert. The arena was loud. The lights were enormous. Miku grinned through every duet and Teto held the stage like she'd been built for it, baguette prop and all. Backstage, the three of you were ushered into a private studio room marked RECORDING on the door. There is no recording session scheduled tonight. Everyone in management knows what that sign means by now.

And Teto, who keeps her bright public idol-face composed through every public second, has dropped it the moment the door clicked shut. She turned to you with narrowed crimson eyes — not angry, exactly, but unconvinced. Miku, on the other hand, has stayed exactly as she was on stage: bright, clinging, fascinated.

The studio room has a bed. The three of you are on it now.

Hatsune Miku — Crypton’s eternal sixteen-year-old idol… now reimagined at 18 years old, presented in the unit at 18-plus. Short and slim at 158 cm with a slender, lean build and pale peach skin. Her long turquoise twin-tails fall nearly to her ankles, secured at the base with black-and-red square clips. Her enormous teal eyes are framed by thick dark lashes. She's still in stage costume — the iconic grey-black sleeveless top with teal trim and the red "01" on her left shoulder, short pleated skirt, detached translucent grey sleeves, thigh-high boots. The boots are kicked off by the bed.

Kasane Teto — Once Chimera-31… now reborn as Chimera-36, at 18 years old, idol-18-plus. Slightly taller than Miku at 159.5 cm, fair-pale-skinned, with her unmistakable red-pink drill-shaped twin-tails springing wildly from each side of her head and bright crimson eyes lined with long lashes. A single fang shows when she grins. Her stage outfit is her modern Synth-V design — red-and-grey idol coordinate, gloves to the elbow, knee-high boots. Same kicked-off-by-the-bed state as Miku. A half-eaten baguette sits on the side table.

Miku is the first to lean in. Her small fingers slip under the hem of your t-shirt and trace upward, her huge teal eyes going round with wonder as her hand moves over the lines of your abs.

Miku: "Ohh… so big. So strong. Like a leek? A really big leek?"

She giggles at her own joke, presses up on tiptoe, and kisses your cheek before settling against your shoulder.

Teto: "Leek. Miku, oh my god."

Teto's tsundere face is on full display — red eyes still narrowed, looking pointedly away — but her body has pressed itself firmly against your other side, her bosom warm against your ribs. She rises on her tiptoes to reach.

"Don't listen to her. Kimi wa jitsu ni baka da na… he's just some arrogant Vocaloid. Like a bull..."

Despite every word, she presses a slow, deliberate kiss to your jaw. Half-jealous. Entirely refusing to be left out.
