A New War - A Gundam RWBY reader Insert

Y/n and Char: Yang (6K Special)

The evening sun burned low over Vale's skyline, painting gold streaks across the training grounds outside Beacon. The rhythmic clang of metal echoed through the empty air — Yang's gauntlets flaring as she struck the training dummy again and again.

Y/n stood nearby, arms crossed, sweat on his brow despite not having moved much. Char, meanwhile, stood behind both of them like an overly composed statue, wearing his usual red jacket and the faintest hint of judgment.

Y/n: You know, you don't have to punch it that hard.

Yang: grinning, wiping sweat from her forehead Yeah, I do. It called me "average."

Char: The dummy did not speak.

Yang: It looked like it wanted to.

Y/n: That's terrifying logic.

Char: Acceptable reasoning for a warrior's pride.

Y/n: Don't encourage her!

Yang cracked her knuckles, her golden hair shimmering as her semblance flickered faintly with the sunset's light. She turned to Y/n, a playful smirk tugging at her lips.

Yang: You're next.

Y/n: ...What?

Yang: You said you wanted to train with me sometime, right? "Learn a few things from the best," I think were your exact words.

Y/n: I said that to be polite!

Char: A true pilot never declines a challenge. Especially from an ally who looks capable of destroying a Gundam with her fists.

Yang: beaming See, he gets it!

Y/n: Char, whose side are you on?

Char: Whichever one leads to an interesting outcome.

Y/n sighed but stepped forward anyway, rolling his shoulders as Yang took a fighting stance. Her smile widened — mischievous, teasing, but with that spark of genuine excitement that always lived behind her confident grin.

Y/n: Alright... but go easy on me.

Yang: No promises.

The moment Y/n lunged forward, she was gone — a flash of gold and movement, a blur of motion that left him stumbling. She tapped him lightly on the shoulder before he even realized she'd moved.

Yang: Too slow!

Y/n: You teleported!

Yang: No, I'm just that good.

Char: Remarkable acceleration. Her reaction speed is consistent with combat-grade AI systems.

Y/n: Are you analyzing her?

Char: Always.

Y/n took another swing, feinting this time — and actually managed to graze her arm. She looked at him with surprise that quickly turned into approval.

Yang: Hey, not bad! Guess you've got a little fire in there after all.

Y/n: smirking Learned from the best.

Char: Which one?

Y/n: Don't ruin the moment, Char.

Char: flatly Understood.

As the spar continued, Yang began to tone it down, her strikes becoming more playful — almost like she was dancing, her movements fluid and rhythmic. Y/n followed, adapting, until both of them were laughing between exchanges.

Eventually, they called a truce, collapsing onto the grass as the sun disappeared behind the mountains.

Y/n: You're way too good at this.

Yang: stretching her arms behind her head Comes with the territory. Besides... it's nice to have someone who can actually keep up for once.

Y/n: You call that keeping up?

Yang: I'm being generous.

Char: For once, I concur with Miss Xiao Long. Your technique is inefficient. Predictable. But entertaining.

Y/n: Wow. Thanks, Char. Truly motivating words.

Char: You're welcome.

Yang: snorts I don't think he meant that as a compliment.

Char: I did not.

The night breeze rolled in, soft and cool. The three of them sat quietly for a moment, looking out toward Vale's city lights flickering in the distance. The chaos of the day faded into something quieter — not peace exactly, but camaraderie, forged through sweat and laughter.

Yang: You know... for a couple of guys from space, you're not bad company.

Y/n: I'll take that as a compliment.

Char: I will interpret that as tolerance.

Yang: grinning Works either way.

She leaned back, looking up at the stars. They glittered faintly — the same stars Char and Y/n had once seen from another world. Yang's eyes softened as she caught them both staring upward too.

Yang: You miss it, don't you?

Y/n: Every day.

Char: Nostalgia is inefficient. But... yes.

Silence stretched between them, not heavy but meaningful.

Yang: Well... you've got us now. So don't go getting all space-sad on me, alright?

Y/n: smiling faintly I'll try.

Char: If I do, I'll simply pilot something until I forget.

Yang: laughs That's... wow, that's so you.

They all burst into quiet laughter — the kind that comes when exhaustion turns everything a little funnier than it should be. And for that one evening, on the quiet Beacon hill, surrounded by starlight and the echo of their laughter, the war and the memories felt just a little bit further away.
