36 Dating Sim System in Two Worlds

So, as you might be wondering, this is actually just one idea but I thought of two possible anime worlds for it to take place in. Obviously I need to talk about the system first and then I'll tell you about the two possible choices. I mean, some should understand without me needing to, but it's for those who haven't read that particular light novel.

For the most part, it's a system which makes the MC like a dating sim character, with stats such as Academics, Physical Ability, Art, Music, Communication, and Charisma. These can be leveled by doing actions pertaining to the stat, so exercising would increase Physical Ability and also affect Charisma if the MC is unhealthy. There is also a shop, where points can be spent on gifts for girls or other special items. The MC is also able to purchase skills from the shop, gaining the corresponding ability nearly instantaneously.

First possible choice is To-Love-Ru, where the MC constantly finds himself in perverted situations with various women. It's one of your standard harem anime/manga, a hallmark, so why not make it a bit more interesting? I believe that by either giving Rito the system or by having someone transmigrate into his body we can make the scenarios better. Plus, we can make the original MC less of a coward and willing to be with his various harem members.

The second option is Monster Musume, with its large range of various demi-humans and other monsters. Obviously you could use the same plot ideas as for To-Love-Ru, where either the MC gets the system or someone transmigrates into his body, but since near identical circumstances could happen to anyone in that world, why not make a completely different person? You could easily make a harem of never before seen monsters for this new MC who, with the benefits of the system, is able to effortlessly catch their affections.

Of course, you don't have to limit yourself to just these two, you could easily use this system in just about any harem story. I mean it would also make a lot of sense in something like Date A Live or The World God Only Knows.
