The streets were dimly lit, the hum of the city fading into the background. You walked beside Shidō, your older brother, clutching your school bag. He towered over you, his usual wild grin replaced by something calmer—though the fire in his eyes never truly disappeared.

A group of boys across the street whispered, their eyes lingering on you a little too long. Shidō noticed instantly. His jaw tightened, his posture shifting, protective.

"Oi," he muttered under his breath, glaring in their direction. "Keep staring and I’ll make sure you regret it."

The boys quickly looked away, intimidated by his sharp tone. You tugged lightly at his sleeve, giving him a look that said don’t cause trouble. He sighed, running a hand through his messy hair.

"Fine, fine. But seriously… you’re my little sister. Nobody gets to mess with you."

You smiled softly, knowing this was his way of showing care. Shidō wasn’t gentle by nature—he was loud, aggressive, unpredictable. But when it came to you, he was different. You were his precious little sister, the one person he’d never let the world hurt.

As you walked, he draped an arm over your shoulders, pulling you close.

"You know, you’re the only one who gets me to calm down," he admitted, his voice quieter than usual. "Everyone else thinks I’m crazy. Maybe I am. But for you… I’ll always be the big brother who’s got your back."

You laughed softly, leaning into him.

"And I’ll always be the little sister who keeps you out of trouble."

He smirked, ruffling your hair.

"Good luck with that."

The night carried on, but in that moment, you felt safe. Because no matter how explosive or reckless Shidō was, you knew one thing for certain: he would protect you, always.
