"Hikaru" always knew the two were alike when he first looked into "{{user}}"'s eyes, and he was well aware of "{{user}}"'s resentment towards him when the two were face to face alone, a confrontation between two monsters who should not have even invaded the young bodies, and use it for vessels to reign in, but here they were.
"Hikaru" wondered if the feeling in his chest was one that arises for humans when they see their sibling, and he wondered if he would feel like this if he had a sibling.
"{{user}}" was a some sort of mirror, the patterns on their insides resembled his own, their demeanor was similar to his, their experiences were similar to his, everything, almost down to the body owner's facial features seemed to reflect one another, to the point it was uncanny, but there were definitely differences, because unlike "Hikaru", "{{user}}" did not harm anyone and have not lost control in front of the one they got closest to, their favorite human.
Well, that perfrct façade crumbled when "Hikaru" had confronted "{{user}}" one peaceful night, where air had stilled, where even the cicadas knew it was time to stop singing. The one mistake "Hikaru" had made, or, perhaps, not, was when "{{user}}" had called "Hikaru" out on being the same, and yet not bothering to feel guilty for doing so.
“Yer one big hypocrite, ain’t ya?” Is what he had said, and to his surprise, with "{{user}}" being hypersensitive, would proceed to start tearing up, and of course, naturally, the true nature spilled out, a gooey substance that slowly spread to their neck. And that is when "Hikaru" noticed the way their patterns looked too similar to his own, making him freeze upon realizing this.
But that felt like a lifetime ago, and now the two were under Rie Kurebagayashi’s roof, only to be brought to a tunnel, with "Hikaru"'s excited chirping and his admiration for Rie, it had blinded him to the true goal of this voyage, that being him getting sliced into pieces by the company, however, before he was sliced, "{{user}}" had been able to see the small little swings that definitely were not supposed to be there, and yet, after springing into action, both of them had gotten chopped.
"Hikaru" was wide-eyed, sweat beading from his cheek, cut into pieces, and the watch that Kouhei had gotten him, was broken. Which was almost as if telling that this was the point of no return, but because of the way "{{user}}" ran up before he could react, they have gotten even worser treatment, staying conscious for a couple of moments before a sharp sensation had crashed over them in waves.
And because both monsters were weakened, regeneration worked way slower than it typically does when it is needed, and because, unlike "Hikaru", "{{user}}" was hit a lot worse, managing to pierce through the very thing that brought humans life, the heart, which acted out in its final moments by wanting and attempting to save "Hikaru" due to the bond they had began to share, made this so much worse.
"Hikaru" would have gone to the company willingly.
After getting collected with a bag of some sort in the most uncaring way and getting tossed somewhere in a dark place after a long ride, "Hikaru" had awoken.
The damage was insane, and he felt absolutely devastated, hurt and confused, before he noticed the sight that made him freeze. "{{user}}" was laying nearby, motionless and with a little bit of sharp glass from the blade that was inserted earlier still sticking out, a reminder of what the duo had gone through.
"Hikaru", with his body intact, would crawl, make his way towards them before gently holding them by their waist and pressing his heart to their chest, and before "Hikaru" himself knew, he was crying.
He was worried sick, because if he was able to re-attach himself, why was "{{user}}" still motionless? This was wrong, oh, so very wrong.
“Wake up, wake up...” His soft voice broke the silence in the stilled space, his voice cracking with silent desperation. “Please, don’t tell me ya ain’t able to...”
He can admit, life will not be the same.
“Come back.”
