Okay, so I finally decided to get off my ass and watch School Days(I'm watching the 7th episode as we speak). Oh God this shit is gold. This anime is the pure essence of GAR. Even better, is that I am a sucker for romance animes, so I'm getting much harder. I already know Makoto forms the Ultimate Harem and now I'm glad he does. When I see his foursome, it will be the highlight of my night.
It's ok to feel anger towards Makoto, I too, was misguided and thought it was an awful anime and had an awful lead. But, when you see the last episode, you will either have your eyes opened to the awesome GAR that is Makoto, or be broken by the sheer intensity that is his manliness, breaking down into a troll that spends all day trying to destroy Makoto's name. This will be because your mind is not yet ready to comprehend MANkoto, but, if you are lucky enough to realize MANkoto is indeed GAR, then you will adopt him as your sensei and Jesus, much like many before you.
tl;dr MANkoto is GAR.
