Summary
Unable to take the pain inside him anymore, Karamatsu decides to take his own life. He had thought it would as simple as taking a bunch of sleeping pills, and going to sleep, but he soon found out that death isn't just a concept; it's a person. A person that strangely looks just like him, and is pissed.

Summary
Once upon a time ago, the sextuplets had been famous for being impossible to tell apart (even by each other). Now though, twenty years later, they were so different that they might as well have been regular brothers instead of sextuplets.
At least that's how Osomatsu felt.
If he didn't do something soon, then his brothers would become so different that nothing would keep them together. Keep them with him.
What could he do though?

Summary
The thing claimed to be Osomatsu, the eldest of the brothers. It wore his red hoodie, laughed in the same obnoxious way he did, knew how to annoy each of them just like he did, and even did the same tics that Osomatsu did, but Ichimatsu wouldn’t be fooled.
This was no monster though. No cryptid that was trying to lure him away to the afterlife. No shapeshifter that was trying to take over his body next. No, those things would be easier to deal with. Easier to handle.
This was something far worse.
"Just stop it, Karamatsu," Ichimatsu growled. "Osomatsu is dead."

Summary
Atsushi loved the feeling of power: He loved it when people threw themselves at him, kissing his ass in hopes that he would choose them as the lucky ones to spend his time with. All he had to do was smile, and people would grow weak in the knees.
It was fun, but not satisfying. It was too easy to encounter people like that. What he really wanted was someone who wouldn’t bend to him so easily. Someone he had to work for. Someone who would fight him all the way, until he could find a crack in their shield and bring them down to his feet.
And he had found that perfect someone.

Ichimatsu's journey to learn that he's actually non-binary.

Summary
(Osomatsu-san, anime)
Ichimatsu understands now. And it's the worst. He's the worst, leaving him with all this knowledge.
That darkness you don't see until you touch it and it infects your fingers. That thought that makes no sense, but feeds on regrets old and new.
He stopped being halfway there everything years ago.
