Harems are fine as long g as you do not go full Akikan40.
I have a rule of thumb of 7 max. that way even on short months each girl has a potential of 4 date nights.
At that point, that's so much filler even if you count out a few of the dates. Harems, just don't mesh out well if you don't plan it throughly unless you're more in for the fanservice rather than the story.

Sad she lost the leg. Wonder if theres going to be any sort of gimmick in the future with the leg. Maybe he can make her a boot to match it.
Have something like magic boosters, springs, skates, and whatever else.
