The demon would say so if it could actually smell. Unfortunately for complete agreement on most any topic, it actually does rely on its host's sense of smell. And he doesn't really like the smell of smoke.
"I would say so," it says realistically instead with a concealed grin, using its free arm and hand to wave the smoke around a bit.

"That's a good point," Akuma says, its hand briefly transitioning to the position it would be in as if holding a knife, possibly its variation of making a bad pun somehow, while its other hand reaches back to push the door completely closed. "So, which is first? Chaos first, food later? Or the other way around? Do you deities even have to eat?"

"I don't remember, so I guess I'll take that as the truth," Akuma says with a wink. "Say, say, though, how do we keep the people who can cook from dying?"

"What are the ones who look like cooks?" Akuma stares hard at the wall like it somehow has the answer, as if a cook would be framed there perhaps. "Are they the ones with the red noses?"
No, Akuma, those are clowns.

"Big white hats and a lot of white." Akuma's grinning now. Not that it wasn't before. "Sounds like someone from a lab."

Cone...???
"Duly noted. Though, where could they be?" He took a few steps forward that were meant to be tentative.

(No no Forengard chefs have cone hats. Nuuuu why'd you edit that ;( )
"Kitchen?" Akuma looks around. Spying a door, he grins. "We're coooming."

"Hmmm?" Akuma looks back at the door. "We locked the door already, though? If we kill people in plain sight, the annoying law enforcement is probably gonna come."

Akuma stalks in the nearest most convenient direction.

Akuma's going to another section cheerfully.
As all chefs with logic would be like, no one is in the kitchen.

"Oh! Hey!" Akuma's voice goes near the back of the place. It's clearly not directed towards Oblivion, though perhaps he should go join the other.

Akuma doesn't visibly acknowledge Oblivion. Right now, it's too busy plastering a highly convincing smile on the chefs in the outside back, who really do not look like they expected "people" to appear from inside a burning building. Also, other than the chefs, the other people who work there are there as well, so there is quite a number there.

Akuma tilts his head.
"W--well," one of them says. He seems like a chef with his attire. "Hello? Uh, the inside is on fire, I guess."

"Don't know," another says with a shrug. "That's why we called the fire department and why, uh, we weren't expecting you to come out from there. You know, smoke inhalation is dangerous..."

"Because we're not experts there," she continues. "You know, we cook and clean, or do whatever we do. We don't know the properties except for fire except they burn."
"And spread," the other pipes up. "So we're staying outside for now. We'll be with you after the fire department comes, though!"
