In the neon-lit city, whispers spread about a new kind of hero—not red, not blue, but turquoise.

They called him Turquoise.

No one knew his real name, but at school, Oikawa Tooru smirked like he knew something everyone else didn’t. He’d lean back in his chair, spinning a pen between his fingers, eyes glinting with mischief.

“Another villain caught last night,” someone would say.

Oikawa would just grin. “Must be a pretty amazing guy, huh?”

What no one saw was what happened after sunset.

The moment the city darkened, Oikawa stood atop a skyscraper, the wind tugging at his turquoise suit. The mask hugged his face, sharp and sleek, glowing faintly under the city lights.

Below, chaos.

A runaway truck. Screaming people.

“Ugh, can’t you guys go one night without trouble?” he muttered, before leaping.

A thwip!—a strand of shimmering turquoise web shot out, sticking perfectly. He swung down with effortless grace, flipping mid-air like it was a volleyball set gone dramatic.

He landed right in front of the truck, planting his feet.

“Alright, let’s not ruin the roads, yeah?”

With a sharp pull of his webs and a ridiculous amount of strength, he slowed the truck to a halt. The crowd stared, stunned.

Someone whispered, “It’s Turquoise…”

Oikawa straightened, brushing imaginary dust off his suit.

“Please, hold your applause. I know I’m amazing.”

But just as quickly as he appeared—thwip!—he was gone again, swinging between buildings like he owned the sky.

The next morning?

Back in class, Oikawa yawned loudly.

“Man, I barely slept.”

His friend narrowed their eyes. “You always say that.”

Oikawa just smiled, resting his chin in his hand.

“Guess I’m just busy saving the world.”

No one believed him.

…except the city.
