He'll open the door, yeah, that'll be noticeable but it could have just blown open.

Well, there's no one around on the first story to notice anyways.

Anything to hear? What about if he goes up the stairs?

Yep, then he can hear a man laughing, followed by them saying something unintelligible to someone else, followed by a woman whimpering.

And if he follows this sound...

He will find himself in a reasonably well decorated common space, not as nice as Lucette's, where a man with blue flames licking at his skin and hair is standing over a young woman with torn clothing. The man is smiling, while what might be his friend is standing nearby, inspecting his fingernails, seemingly bored. Two other women huddle in a corner, while a fourth is facedown, unmoving.

She have a pulse?

Yep.

He looks for Lucette out the window to flag her down.

She's watching from across the street.

Lamp: lit. Glass: applied.

She could go through the wall, but orange doesn't indicate an emergency that would justify that, so it's down through the front door and up to the second floor, where she's on the flaming empowered before he has time to react, clapping her hands over his ears and sending a shockwave through him in the process, knocking him out.

The other, empowered on the other hand, has time to react, irises expanding to fill his eyes, followed soon after by his pupils, followed by his irises blossoming once again from the center of the inky blackness, repeating.

"How about instead of harassing my friend, you join our fun," he suggests, staring at the hero with his strange eyes.

Lucette takes a step toward him before collapsing forward, holding herself off the ground with both arms and breathing heavily.

- does that only work if she can see this guy's eyes, what if Haru stands between them.

Still breathing heavily!

"Are you really so unable to let loose?" His eyes start moving faster than before.

Whimper.

"...Are you a girl?"

.......Suppose Haru just kicks this guy in the crotch really hard, will that make him cut it out.

Haru definitely hurt one of his toes doing that but the guy doubles over, losing sight of Lucette.

Who is going to charge at him.

The villain manages to look back at her before she gets there, his eyes pulsing more rapidly than either previous time.

But her momentum carries her into him, there will be a dent in the wall behind him, but that's fine because he blinked at the impact, giving her the chance to punch him hard enough to knock him out as well, further denting the wall behind him.

Ow, his foot, hopefully that's just stubbed but these shoes are not steel-toed. He's going to stand over that guy in case he tries to come around and let her decide what to do with the rest of the people in the room.
