Do you have to much free time? How about a pension for occasional loli, milf, borderline incest, nip slips, and an unconventional ending for a harem?
Sounds like you need to read this manga then.
Plot:
Yomeiro Choice Manga Summary:
"The story is about Saku, a high school student who lives with his cousin Ran and has a childhood friend named Karin. It turns out a girl suddenly appears in his house and claims to be Karin's and Saku's child from 10 years in the future. Not long after, another girl appears...
My Summary:
A girl shows up claiming to be the main character's daughter, saying she is the child of him and one of his childhood friends. This girl has come from the past because she fears something may occur which will keep her from being born. Soon another girl shows up claiming to be the child of him and another long time friend. She shares a similar goal as her predecessor. Things just get crazier from there.
I won't sugar coat it, this is fairly standard of most harem, except it is targeted towards more adult readers. It has the normal tendency to sprinkle small amounts of a real story in between countless chapters of nonsensical plot devices and unnecessary activities.
Really what I liked about this was the ending. It does leave you feeling unhappy with no epilogue however from the last chapter everything it tied up and answered. I just wanted to see how everything wound up.
For those who like harem manga but have no intention of reading this manga. Well, I'll spoil the ending here so you can understand what I mean. However if you might or will read it don't spoil it, it isn't too long of a read.
Time is a central factor in this manga. His children travelling back in time as well as forward to their respective future for a momentary back story if you will. However at one point his fourth child (the last one, promise...kinda) fades from existence because things had changed between her mother and the main character. He didn't realize this and neither did the mother but it sets up the main resolution.
He awakes being the only one who remembers the child. From here on I'll call her by name because it was the only one I bothered to remember. Cerulean. He can't understand why no one remembers Cerulean, he goes outside and is greeted with a disembodied voice. An attractive woman appears and explains that she was erased from the world because of his actions. Obviously this crushes him. This woman then goes on to put him through three trials to see if he will finally choose a wife (a path to go on). I said earlier time was critical in this, the reason for it was this man had multiple paths he could take, some would end all life, some would keep his children from being born, etc. She was here to give him an ultimatum. She gives elementary explanations of multiverse as well as cause and effect to get him to understand.
She gives him the option to leave everyone behind and stay with her. Everyone will forget about him and he won't have to deal with the life he has resentment for. He agrees.
She then tells him that she is also from the future. One in which he dropped everything he cared about and filled with disdain devoted himself to science and machinery. He became consumed and eventually created machines which he unintentionally gave his hatred for humanity. They destroyed the humans. She was his assistant, that he had created. So it's his other daughter. Damn this dude fucks a lot.
The chat they have gives him new resolve to make the future what he wants.
In the end he chooses a path, he acknowledges that he loves all of them. Having finally chosen his path the worlds The worlds he desires merge and he is with all his children and their mothers. Their future has been altered but we don't get to see that. Everyone is happy, Cerulean isn't dead, polygamy is alright with them all and even his mechanic daughter from the future is there. Then I'm pretty sure the last panel is the start of an orgy with everyone.
