There aren't too many multi-part scenarios in these stories that aren't connected to the main arcs of each, but sometimes I'll have a connection just because the prompts happened to mesh well in my mind. This is one of those situations.
Basically the golden rule is: if you wanna piss off a Kaiba, mess with a kid.

Seto strode into the room like a thunderstorm in a suit, with Kisara at his right hand. Noa, for his part, whirled on his heel and glared at his brother. It took him a number of breaths to finally calm down enough to step away, and the feral rage left his face. He still looked like he wanted to chew off someone's limbs, but it wasn't imminent anymore.
Noa jabbed a finger at the people huddled behind the principal's desk—not just the man himself but his receptionist, a security officer, and multiple students (the only ones who were enjoying this)—as his face twisted with new fury.
"I don't know what kind of circus you're used to," Noa snarled behind his teeth, "but I do not allow anyone to harass or endanger my people." Ryo Bakura was standing near a wall, behind Noa, looking flustered but not exactly displeased by his partner's anger. "I hope you have an easier time dealing with this nonsense because I am ten seconds away from ripping this building down with my bare hands."
Seto did not miss that Noa's language, while curt and tremendously insulted, was carefully considered. He was not cursing, he was not ranting. He was clipped, clear, and to the point. He was, if nothing else, very precise. Seto wondered if this was for the students' benefit, for Seto's benefit, or simply what happened when Noa was actually angry and not just pretending.
As he usually did.
Seto glanced casually across the desk.
"Mister Kaiba, thank God you've—"
"Did any of you put your hands on this gentleman?" Seto asked, his voice quiet, deathly calm, as he gestured at Ryo. His face was untouched by feeling, but his words dropped the temperature in the room by at least ten degrees.
When nobody spoke, Seto turned to Ryo. "What happened here?" he asked.
Ryo cleared his throat, and gestured with the clipboard he was holding. "Mister Kaiba," he said, nodding toward Noa, "was going over a list of municipal violations he wanted addressed. Safety issues, you understand. I was asked to take down notes during this appointment, and so that was what I was doing. When Mister Belfast—" Ryo nodded at the principal now "—lost patience, he demanded that we leave. When Mister Kaiba refused to leave until his concerns were addressed, Mister Belfast seemed to think that it would be best to . . . confiscate my clipboard. Something about the privacy of the student body."
Seto sighed. "Thank you," he said. He turned to Kisara. "Please escort my brother and Mister Bakura from this office, won't you?" He turned his icy disposition on the principal. "It seems that I was mistaken in my belief that the faculty here would be accommodating, and that this situation would not require my direct intervention." He turned to Ryo again and bowed his head. "I apologize for the trouble I have caused you. Please follow Miss St. Vincent."
Ryo nodded and stepped closer to Noa.
They followed Kisara from the room, Ryo stepping carefully while Noa stomped.
"I'm going to strangle that son of a bitch with his own intestines—"
"Now, now," Kisara said, but she was smiling. "None of that, Noa. I can't have anyone upstaging me." She turned to Ryo. "Are you quite all right? You were not injured, yes?"
"No." Ryo shook his head.
"Good." Kisara turned her attention back to Noa. "What happened in there?"
"Do you know how many hazards are in this place?" Noa asked. "The wiring is a goddamn travesty. Half the portable rooms don't have functioning air conditioning anymore, and the other half never fucking did in the first place!"
Kisara scowled. "This is the precise trouble my prince anticipated."
"Oh, I'm sure he did." Noa nodded. "These types are all the same. They get block grants and then pay as little as possible as lip service to maintenance work, and then God only knows where the rest of it goes. Probably Belfast's bank account, if I'm being realistic. Fucking jackass."
Noa paced about the hallway as they waited for Seto to finish meeting with the faculty, likely going into a similar speech as he was right now—only more practiced—and he looked like he wanted nothing more than to eat someone. His hands were like claws, and he wanted to dig them into something. Someone. Anyone.
The only thing stopping him from finding a victim was the understanding that there were children in this building.
"If I didn't know better," Kisara murmured, "I would think that he was mad."
Ryo smiled fondly, saying nothing.
