Some people never define their relationship and remain fuck buddy until they both find a real partner and that's okay. It's what happened here, they were strongly attracted to each other but they weren't devoted to one another, which is why their "romantic" relationship slowly fizzled out. Just be happy they are still good friends and were able to find someone else to love.

Kirino is a straight transgender girl and Mishima is a gay cisgender boy. There was no way they would ever end up together romantically. I'm saying this because it seems like there's some confusion in the comments.
It would have been adorable if they could have lived together as roommates in Tokyo while being their true selves though. Alas Kirino didn't get that chance.

Well kirino is still a 'he' not she, he's not a woman. He wanted to be woman tho. And I think he did find his happiness, maybe not the one he dreamed about when he was young but the one he thought would be much easier to achieve without ruining his mother's. Nd I think kirino nd Mishima needed each other as 'friends', nd not anything else. I just wish Mishima nd kirino could've stayed in contact nd I hoped that kirino's mom could one day accept her son as he truly is nd get over it but ig that was too much to ask of her.

About Akitora learning that Rogi raped Tatsuyuki.
Honestly I don't think he'll care much. First of all the official reason behind the rape was that Tatsuyuki needed to pay for his mistake. So I think Akitora will take it as such.
Besides, let's be honest, he's a shitty dad. I don't think he cares much for his son. As long as he knows he's alive and (semi) well, that's good enough for him. It's kinda ironic how as a young man he despised his own dad yet he failed to raise his son with love too. Turns out they weren't so different after all.

"Tatsuyuki, don't grow up to be like me, okay? This kind of empathy brings you nothing but trouble."
That's so cute because he grew up to be exactly like her, despite her not being around.

Yes, she's super cool. Yes, Akitora is cheating on her and it sucks. But she also knowingly married a yakuza. That means she chose to condone anything he might do including typical yazuka activities such extortion, torture, physical violence, rape, murder. She also knows that in yakuza culture, men aren't faithful. In fact it seems that before Rogi, Akitora wasn't sleeping around with prostitutes which means he was pretty faithful to her all things considered.
So yeah Rogi and Akitora are trash but let's not act like she's some innocent maiden either.
Also friendly reminder that Nozomi from Yondaime is also a rapist since he took advantage of Tatsuyuki being drunk and mistaking him for his doctor to have sex with him.
No one in this story is innocent.
