Question? So when the MC is sent forward in time five years in the next region and meets the human girls again would it be their THIRD time meeting him and are ready for the third set of kids but only the second time for him. The second time the human girls meet him was on his revisit trip to each region after the end of his journey so now they meet him again.
A few small ideas
1: If on the ship a side scene was to tell about the MC's daily schedule. Part of it is him going to the nursery on the ship to read stories to the eggs since he would want to try to spend some time with them before they get sent to Maple even if they have not hatched yet and try to be a good father somehow.
2: If some of the legends were to try to make the MC some breakfast one item could be similar to PANCAKES but in a sexy way. This would only work for the girls that are extremely resistant to heat and fire like Groundon. With the help of the rotom to make the batter it would be placed on their butt or breasts to make ASSCAKES or TITCAKES that could be eaten right off of them.
I do have another idea but it is pretty BIG with multiple side scenes that are hilarious and fit extremely well with many of the legends so I will wait till after the ship update or when Chainsaw feels he has reduced their backlog of ideas.
