If your bend is an age gaps or creampies, have I got a treat in store for you! I also picked this one since one of the protagonists has the same name as our lovely Manna-chan! Well, give or take an “n”, anyway. And since Mana-san and our own Manna-chan both have lovely sets of breasts, I think that makes up for any differences in their names.
Written by Saigado, the Japanese title of this series is Mana-san to Omoya wo Hanarete…. That translates to something like “Leaving the Main House with Mana-san”. This is something of a play on words, though. Haranete means leaving or separating, while hanare is the Japanese term for an outbuilding, like an annex or detached house. And in this 2-volume series there is a lot of action that happens in a detached house, among other places.
Subaru Kanameishi is a 19-year-old young man. He is living in Tokyo with his father and recently graduated high school. But his father Ginga recently had a stroke and is in the hospital recovering. Subaru is a little concerned about the coming medical bills. The lengthy hospital stay and rehabilitation will be hard to cover without Ginga’s income from work.
All is not lost, because Fate knocks on the door. Fate, that is, in the form of a mailman. Subaru receives a letter from his uncle Tokuichi. He is being summoned to see his father’s estranged family located deep in the countryside a several hour journey away. Subaru hasn’t been there since he was a young kid. It isn’t clear why they called to see him now ,until he arrives and finds himself suddenly in a meeting. Present are his uncle, his aunt Mana, and his two great-grandmothers.

They have a proposition for Subaru. You see, it turns out that the Kanameishi family, has a problem. Once a prosperous, powerful lineage, they are dying out with no heirs. The town is full of old people and all the young people have moved to the city. They need someone to carry on the family line, and not just anyone will do. They are a proud, powerful line, and they need someone of a certain level of blood purity. As you perverts have come to expect, yes, they want Subaru to impregnate Mana!
Hoping for a little NTR action? Well, you’re out of luck, there; you see, Mana isn’t Tokuichi’s wife, she’s his daughter. While she’s 36 years old, she’s actually Subaru’s cousin. As such, as Tokuichi explains above, it’s apparently completely fine and legal in Japan. I’d always assumed it wasn’t allowed, but I suppose that was rather ethnocentric of me.
Anyway, while Subaru is understandably shocked at the idea of banging his aunt/cousin, the matriarchs offer something he needs; the family will pay for his father’s medical bills if he shoots a baby into Mana. They don’t even want him to stick around to raise the kid; they just need his baby juice. Forced into a situation where he doesn’t really have much of a choice, he agrees, and thus begins the story with him and Mana staying in a detached house on the grounds of the main house (the aforementioned hanare) for a little privacy while they have sex every night.
One of the things I enjoy about this manga is that as you progress through the chapters, you see our two main characters both grow to genuinely care for one another and as that happens the sex gets better. The first night, it’s quick and awkward as our protagonists are new to each other and also (I suspect) both virgins, so they don’t really know what they’re doing.

But as the series progresses the sex Subaru and Mana have gets better and hotter. They try new positions, have sex in different places, in different clothes, and at different times of day. It’s pretty neat to see them get better at sex and enjoy it more as they both get used to the situation, to each other, and come to care more deeply for one another.
Another thing I really enjoy about this series, and I say that as someone who has come back to it several times, is that it actually has a story, and not just the usual “I’m hot for auntie/my nephew” fig leaf. Porn with a plot is something of a weakness of mine because it combines my two great loves, stories and sex, and with 18 chapters over 2 volumes, this has story and sex aplenty.
You see, Subaru understands something’s not right with the situation. All storied families have skeletons in their closets, and the Kanameishi family is no exception. They have a lot to hide and Subaru, who’s been an outsider his whole life, is trying to figure out just what’s happening in the place he’s got to live in.
As he works to unravel the mystery, he winds up running into two local girls closer to his age, Hotaru, who runs the only shop in town, and Susuki, who works for the Kanameishi family as cook and cleaner. As you might expect, he winds up nailing them pretty routinely, too.

He also winds up banging a couple of other older women who are rather desperate for young-man-dick, usually to pay for information they wind up giving him on the nature of the mystery, which makes me realize how unfair life is. Women never asked me to have sex with them in return for them helping me out when I was younger. They don’t do it now, either, and I’m actually good at sex, now! Back then it would have been like casting pearls before swine, but now I actually make women feel good! Oh well, I suppose life can’t be like ero-manga. *sigh*
Anyway, I come to (heh heh) this ero-manga pretty regularly. With two volumes dedicated to one story means there’s time for an actual plot to develop and the twists and turns are interesting. On top of that, the artwork is good and the sex scenes are hot. There is one thing I don’t quite get, though. If Subaru is 19 years old, why is he smaller than all of the women older than him while the same size as the women about his age?
Putting that aside, it’s fun to see Subaru and Mana become closer together. While the age gap is a little weird for both of them at first, they both are happy and want to be together at the end, and the mystery of the Kanameishi family is resolved in a way I had not expected.
One content warning for you: if a little reverse non-consensual sex bothers you, you might want to steer clear of Chapter 3 of the first volume. Subaru’s first time with Hotaru is while he’s barely conscious and she’s so horned up at the chance of actually fucking a guy she just has her way with him. He doesn’t resist, but he doesn’t really know what’s happening until the next day. Ultimately he’s fine with it (he is a man in an ero-manga, after all) and after that it’s all consensual. Otherwise, if you like older women, younger women, bigger titties, smaller titties, cousin fucking, creampies, a whole lot of girls fingering themselves or just an interesting story where a young man tries to figure out what his family’s been up to, check out this series. It’s great!
