They aren't the same.
Hiroomi has known that for a very long time.
So he doesn't say a word when she answers the door wearing nothing but a semi-bloodstained sweater. It's long, and covers everything, though pants would have been nice. She blushes when she sees him, though she had been the one to call him.
"He's…um, he's not awake yet, but—"
"I've got it."
Her apartment is small, cheap, and cluttered with all sorts of youmu-related paraphernalia. There are scorch marks on the walls, gouges in the couches, and stains on the carpet. That is all the youmu's fault.
The figure lying naked on her bed is her fault.
And, despite her assurances, he's awake and wavering in that half-awake state that makes Hiroomi's heart ache.
Like that, they're content with him. They never look at her, never acknowledge her presence. Like that, Hiroomi wonders if the youmu clings to her so tightly because she is the only one capable of calming him, while Hiroomi can only offer Akihito's death.
Claws brush his cheek, slide, as they always do, downwards, to his back, to the scars there.
"Do you want to stay here?" He asks softly. There is a pause, and Akihito presses against his back with his augmented strength. Hiroomi lets out a small noise of surprise as he falls onto his chest, flickers of power warm and static through his clothing.
It is an awkward position, but Hiroomi rests his cheek on Akihito's chest and studies him, the green-brown eyes staring expressionlessly back at him.
Mitsuki had asked him how it felt to share Akihito with Mirai, not too long ago.
It sucks, those moments when he can do a thing to help and Mirai is elsewhere and the youmu panics. But the youmu isn't Akihito. Mirai is not in love with Akihito. Akihito is not in love with Mirai. And Hiroomi is not in love with the youmu.
Their transformation goes soul-deep.
The claws dig deeper, pressing hard against his jacket, and Hiroomi carefully, slowly, sits back up. It agitates Akihito, and the particles of power curling in the air around him darken, became denser, but Hiroomi is careful to only remove his jacket, his shirt.
The scars on his back were the first scars the youmu had given him, and while they had been by no means the last, Hiroomi suspects that the youmu sees them as his tie to reality, to Akihito and Mirai and even Hiroomi. It was why, whenever the two of them float in that in-between place, they seek him out. Press deep enough to reopen them, if it was bad.
And Hiroomi is content with that.
Akkey is not the only one who had transformed.
