Everything was on fire. That was the first thing Tobirama noticed after managing to slip unnoticed to the lab he had left for these kids. Shukaku's eyes are wide and Tobirama can already tell that these brats are going to be a terrible influence on him. Thank god he had had the sense of mind to make the cupboards storing the explosive materials damn near indestructible.

Once he takes a moment to figure out what the hell is going on, he finds that it isn't as bad as it appears at first glance. All fires are contained, although none of the kids seem particularly interested in putting them out, and in no danger of destroying anything of value.

"Hello," Tobirama says, only a little hesitant. Something in the lab smells unmistakably like plant rot. All the children turn to him at once, eerily in synch.

"Otousan!" Nao cries, entirely too cheerful. She's holding- something with tongs, blueish flames licking at the metal. He vaguely regrets bringing Shukaku along. He does not need his daughter rubbing her pyromaniac tendencies off on an actual demon.

"I see you've been… busy," Tobirama says slowly, sidestepping Michiko when she tries to hug him. It's not that he doesn't want to hug his niece, he's just a tad worried about whatever mystery substance she's practically coated in.

"Papa gave us permission to experiment on it," Kyo defends, immediately spiking Tobirama's curiosity and suspicion.

"It smells bad," Shukaku says matter-of-factly before Tobirama can pursue his questions on what it is.

"That's Nao's fault," Kyo informs, making his way over to Michiko. "Michi, I need some more of that blood stuff." Michiko sticks out at arm and Kyo scrapes off a glob of the white substance- blood? -before making his way just as carefully back over to his desk. Putting aside that for a moment, Tobirama has just realized something else of significant concern.

"Where are Isamu and Asuka?" He asks, dreading the answer.

"Suka got hurt in Samu's explosion," Kyo pipes up, waving about her badly-smelling, burning tongs. "So he's in the hospital and Samu's been banned from the lab for a month." Tobirama suddenly understands Tatsui's massive alcohol supply.
