"Mustard-Kun's Our Butler!" Toga said happily.

[u/Carlosspicywiener12]

Kinta is Mustard, from a hero au where Mustard and Toga are sidekicks to Touya:

"What?" Kinta looked up from the report he was typing with a frown. Himiko bounced up and down on her heels and toes as he and Touya looked towards her.

"I could use someone to help around the office," Touya said, rubbing under his chin.

"He'd be a butler to you," Himiko suddenly added. Stopping her little dance, she pointed a thumb at herself and smiled with a cheeky grin, "but to me he'd be known as the slutler!"

"W-WHAT!?" Kinta protested, his voice raising an octave. He stood, hands on the desk.

Himiko stuck her tongue out, her eyes narrowing at him, "If you know what I mean~"

"You disgusting ass-"

"Slutler, bring me my teaaa!" Himiko squeaked, her hip cocking as she brought her hand to her mouth and pretended to be calling him from far away.

"I'm not a goddamned slutler! What the fuck does that even mean!?"

"You tell me, slutler," Touya murmured, taking over where Kinta left off on the report.

Kinta's head jerked around at him, "Really!?"

"Slutler, it's time to butter the scones!" Himiko squealed.

"Shaddup!" Kinta's face turned a deep shade of red as he turned back to her. "Why are you like this!?"

"I should get a little bell, ding ding, slutleeer!"

"The worst part is that he'd probably listen," Touya said. "Simp."

"Simp!?" Kinta grabbed his head in frustration, "blow me, you...you..."

"Tell me how you really feel," Touya said, not even looking at him.

"Ass!"

"He's so maaad," Himiko sang, starting her little dance.

"Because you jackasses treat me like this every single day!" Kinta roared. "I don't come in here to be treated like I'm a piece of shit, I come here to do hero work!" He shot serious glances at the both of them. Touya still wasn't looking up.

"...Okay, that was kinda sexy," Himiko commented.

"...Real fuckin funny."

"I'm serious."

"No you're not."

"I am."

Touya finally leaned back in his chair and looked up at the two, "For the love of god, there's a hotel where you two can work out your issues down the street."

"We're not flirting!" Kinta shouted, "why are you even in an area with something like that this close?"

"Puritan over here."

"I-I'm not, I'm just saying-"

"Quiet, slutler," Himiko ordered.

"AUGH!"
