A headcanon by toshio-fukawa:
The current Togami head starts building a family in his/her early or late twenties. Prospective harem members are selected from the upper class and undergo tests for intelligence, but only after being intensively screened for any genetic problems. Once this process is complete they are made to sign many confidentiality agreements that require them to keep sensitive information a secret from even their own families. The candidates are then called together, and the Togami head picks one or two that he/she wishes to begin spending time with.
In the case of the Togami head being a woman, the process would end here, with her and the chosen man’s child being carried by a carefully-monitored surrogate. Once everything goes as planned, the man and the prospective-heir are sent away.
If the family’s head were a man, at this stage he would impregnate his woman of choice, and after providing for the woman during her pregnancy she would sent back to wherever she came and be tasked with raising the baby, just like the aforementioned man would be.
In the case of both genders, the Togami family would pay for the child to receive a world-class education and whatever it took to foster any talents. Though the child’s non-Togami parent would have to pay for all of their ponies.
At any time the Togami head can call for the Heir-ship contest to be held. The competition is a series of debates, rhetoric challenges, interviews,
bikini photoshoots and timed tests. All measuring the skills that a future investment mogul would need. At the end of the events, the group is told that a winner has been selected. Suddenly, a staged crisis-situation arises, with the purpose of testing each child’s ruthlessness. Once the guns are revealed to be fake they are presented with the shredded remains of their score sheets, and are told that all of those other things had been meaningless and that the now-resolved crissi situation had been the only test. The most cold-blooded of the children is named the winner, and is then assimilated into the Togami conglomerate.
The losing children are no longer allowed have the family name of ‘Togami’, and they and their parent are banished from the country and thrown away. The winning family gets to have the honor of being tied to the Togami Conglomerate and experiences a great increase in wealth and fame. Because to them, breeding with a Togami was just an investment.
