Can someone explain to me what is the relationship between Akitora and Rogi and Tatsuyuki'...

No I wouldn't say its a polyamorous relationship buuuut Akitora and Rogi have def hooked up and Asami knows that and she seems to be okay with it but I've heard that later on its comes to be a big issue so idk I guess a complicated relationship would be the easiest to describe those three

Well they have more than just hooked up.
I really can't understand who loves who or maybe Akitora loves them both I don't know

I think Rogi loves Akitora for sure but its not the same kind of love that Akitora has for Asami, I do think Akitora loves Rogi too....well maybe? I only say that cause I've only read up to ch. 10 and I havent seen any raws but from what I've heard Akitora chooses Asami in the end so yeah idk either. It will be interesting tho seeing how everything plays out

Rogi is a piece of work but he deserves someone who loves him and devote himself to only him. Maybe Akitora was just a "lesson" i don't know. Well, seeing as he will later rape akitora's son ...

I too think that Rogi deserves someone that loves him and I think that's gonna be Hachi, in fact I'm willing to bet it will be because I don't see how else he would fit into the story. One thing is for sure he def ain't ending up with Akitora. I think it's bittersweet, like it sweet because again I'm almost positive Hachi will be like this saving grace for Rogi so they'll end up being together but then its bitter because Rogi still loves..... or rather has some deeeeep attachment to Akitora especially like you said seeing as what he did to his son its pretty fucked.

Yes i totally think the same thing ! Only tong is that for now, I don't like Hachi

Wait why not? Lol He doesn't seem like like a bad guy, and I haven't seen anything to not like about him...maybe I'm missing something? lol

Maybe because of the way he appeared on Rogi's life I don't really know lol for now it's just a feeling but it will surely disappear once we'll see more of him

I also want to know how his daughter came into being

Ah yes that too I'm really curious about! Like at first I thought maybe she's the child of Rogi and Asami but there's no way that would be possible considering Rogi kinda hates Asami and I doubt she is related to Akitora in any way so yeah idk I don't think she is Rogi's biological child but if that were to be the truth damn I'd be surprised lol but what you said about Hachi coming into Rogi's life.... like I think its verrrry ironic cause the way he ran out in front of his car to like money or whatever is exactly what Rogi did with that older guy in the past sooo to me its like Rogi is getting a taste of his own medicine lol

I don't think that she is his biological child either it is just weird to imagine Rogi with a woman.
Yes Hachi is like a younger version of Togi just more soft.

I think Hachi is there to make him kinda take a look at himself and reflect on his past mistakes. So yeah he's there to teach him a lesson and they'll most likely end together, that how I see it. But I also remember in Yondaime Ooyamato, Tatsuyuki said something like Rogi and his dad will eventually see each other so I think there's gonna be like one last face to face meeting with those two, like a final closure type thing, besides I kinda wanna see what Akitora looks like in his older years.

Yeah.. we'll just have to wait and see how it goes
