Alas the scriptwriter will not be able to create a good harem (especially with the limitations of the genre) with so many girls that will be present in the game. But the plan is to create 3 small harems of 3 girls each. Alas it will not be soon, so for now this genre is not present, so as not to mislead players. And it is not clear whether it will be possible to specify the genre harem, if not all girls are in the harem.
Even if we decide to make one total harem, it would take a long time to get all these girls together. Maybe someday the scriptwriter will be able to realize it, we are considering this option.
