Here you go! Just put him in your saved sims folder. If you have all the sliders from the other Free! sims I made you should be fine, especially since I used Makoto as a base.
The hair I had used on him at the time can be found here, but use whatever you want and you can change his facial features of course (I don’t have any problems with that for any of my sims anyway, haha.) I hope he will be enough to your liking though. :3
This should be be what he looks like (I’m willing to bet most of the clothes I’ve used on him is by Peacemaker-ic.):
For Nitori, if you want you can use Nagisa as a base since they pretty much have similar facial structure in the anime. Unless my facial sliders start working again I don’t know when or if I will be able to do a Nitori. Sorry. (;_;)
